Vuln Rule Version CCI Severity Title Description
SV-52838r1_rule WN12-00-000001 CCI-000366 MEDIUM Server systems must be located in a controlled access area, accessible only to authorized personnel. Inadequate physical protection can undermine all other security precautions utilized to protect the system. This can jeopardize the confidentiality, availability, and integrity of the system. Physical security is the first line of protection of any system.
SV-52839r2_rule WN12-00-000012 CCI-000764 MEDIUM Shared user accounts must not be permitted on the system. Shared accounts (accounts where two or more people log in with the same user identification) do not provide adequate identification and authentication. There is no way to provide for nonrepudiation or individual accountability for system access and resource usage.
SV-53189r2_rule WN12-GE-000001 CCI-000366 HIGH Systems must be maintained at a supported service pack level. Systems at unsupported service packs or releases will not receive security updates for new vulnerabilities, which leave them subject to exploitation. Systems must be maintained at a service pack level supported by the vendor with new security updates.
SV-52103r4_rule WN12-00-000100 CCI-000366 HIGH The Windows 2012 / 2012 R2 system must use an anti-virus program. Malicious software can establish a base on individual desktops and servers. Employing an automated mechanism to detect this type of software will aid in elimination of the software from the operating system.
SV-52840r1_rule WN12-SO-000073 CCI-000366 LOW The shutdown option must not be available from the logon dialog box. Displaying the shutdown button may allow individuals to shut down a system anonymously. Only authenticated users should be allowed to shut down the system. Preventing display of this button in the logon dialog box ensures that individuals who shut down the system are authorized and tracked in the system's Security event log.
SV-52841r2_rule WN12-00-000014 CCI-000366 LOW System-level information must be backed up in accordance with local recovery time and recovery point objectives. Operating system backup is a critical step in maintaining data assurance and availability. System-level information includes system-state information, operating system and application software, and licenses. Backups must be consistent with organizational recovery time and recovery point objectives.
SV-52843r3_rule WN12-GE-000005 CCI-000213 HIGH Local volumes must use a format that supports NTFS attributes. The ability to set access permissions and auditing is critical to maintaining the security and proper access controls of a system. To support this, local volumes must be formatted using a file system that supports NTFS attributes.
SV-52845r3_rule WN12-SO-000022 CCI-000048 MEDIUM The required legal notice must be configured to display before console logon. Failure to display the logon banner prior to a logon attempt will negate legal proceedings resulting from unauthorized access to system resources.
SV-52846r2_rule WN12-SO-000024 CCI-000366 LOW Caching of logon credentials must be limited. The default Windows configuration caches the last logon credentials for users who log on interactively to a system. This feature is provided for system availability reasons, such as the user's machine being disconnected from the network or domain controllers being unavailable. Even though the credential cache is well-protected, if a system is attacked, an unauthorized individual may isolate the password to a domain user account using a password-cracking program and gain access to the domain.
SV-52847r1_rule WN12-SO-000052 CCI-001090 HIGH Anonymous enumeration of shares must be restricted. Allowing anonymous logon users (null session connections) to list all account names and enumerate all shared resources can provide a map of potential points to attack the system.
SV-52848r1_rule WN12-AC-000002 CCI-000044 MEDIUM The number of allowed bad logon attempts must meet minimum requirements. The account lockout feature, when enabled, prevents brute-force password attacks on the system. The higher this value is, the less effective the account lockout feature will be in protecting the local system. The number of bad logon attempts must be reasonably small to minimize the possibility of a successful password attack, while allowing for honest errors made during a normal user logon.
SV-52849r2_rule WN12-AC-000003 CCI-000044 MEDIUM The reset period for the account lockout counter must be configured to 15 minutes or greater on Windows 2012. The account lockout feature, when enabled, prevents brute-force password attacks on the system. This parameter specifies the period of time that must pass after failed logon attempts before the counter is reset to "0". The smaller this value is, the less effective the account lockout feature will be in protecting the local system.
SV-52850r2_rule WN12-AC-000001 CCI-002238 MEDIUM Windows 2012 account lockout duration must be configured to 15 minutes or greater. The account lockout feature, when enabled, prevents brute-force password attacks on the system. This parameter specifies the period of time that an account will remain locked after the specified number of failed logon attempts.
SV-52108r3_rule WN12-UR-000003 CCI-002235 HIGH The Act as part of the operating system user right must not be assigned to any groups or accounts. Inappropriate granting of user rights can provide system, administrative, and other high-level capabilities. Accounts with the "Act as part of the operating system" user right can assume the identity of any user and gain access to resources that user is authorized to access. Any accounts with this right can take complete control of a system.
SV-52851r1_rule WN12-AC-000005 CCI-000199 MEDIUM The maximum password age must meet requirements. The longer a password is in use, the greater the opportunity for someone to gain unauthorized knowledge of the passwords. Scheduled changing of passwords hinders the ability of unauthorized system users to crack passwords and gain access to a system.
SV-52852r1_rule WN12-AC-000006 CCI-000198 MEDIUM The minimum password age must meet requirements. Permitting passwords to be changed in immediate succession within the same day allows users to cycle passwords through their history database. This enables users to effectively negate the purpose of mandating periodic password changes.
SV-52853r2_rule WN12-AC-000004 CCI-000200 MEDIUM The password history must be configured to 24 passwords remembered. A system is more vulnerable to unauthorized access when system users recycle the same password several times without being required to change to a unique password on a regularly scheduled basis. This enables users to effectively negate the purpose of mandating periodic password changes. The default value is 24 for Windows domain systems. DoD has decided this is the appropriate value for all Windows systems.
SV-52854r4_rule WN12-GE-000014 CCI-000795 LOW Outdated or unused accounts must be removed from the system or disabled. Outdated or unused accounts provide penetration points that may go undetected. Inactive accounts must be deleted if no longer necessary or, if still required, disabled until needed.
SV-52855r1_rule WN12-SO-000003 CCI-000804 MEDIUM The built-in guest account must be disabled. A system faces an increased vulnerability threat if the built-in guest account is not disabled. This account is a known account that exists on all Windows systems and cannot be deleted. This account is initialized during the installation of the operating system with no password assigned.
SV-52856r1_rule WN12-SO-000006 CCI-000366 MEDIUM The built-in guest account must be renamed. The built-in guest account is a well-known user account on all Windows systems and, as initially installed, does not require a password. This can allow access to system resources by unauthorized users. Renaming this account to an unidentified name improves the protection of this account and the system.
SV-52857r1_rule WN12-SO-000005 CCI-000366 MEDIUM The built-in administrator account must be renamed. The built-in administrator account is a well-known account subject to attack. Renaming this account to an unidentified name improves the protection of this account and the system.
SV-52858r1_rule WN12-GE-000010 CCI-000366 MEDIUM The system must not boot into multiple operating systems (dual-boot). Allowing a system to boot into multiple operating systems (dual-booting) may allow security to be circumvented on a secure system.
SV-52106r2_rule WN12-GE-000026 CCI-000366 MEDIUM File Transfer Protocol (FTP) servers must be configured to prevent anonymous logons. The FTP service allows remote users to access shared files and directories. Allowing anonymous FTP connections makes user auditing difficult. Using accounts that have administrator privileges to log on to FTP risks that the userid and password will be captured on the network and give administrator access to an unauthorized user.
SV-52212r2_rule WN12-GE-000027 CCI-000366 HIGH File Transfer Protocol (FTP) servers must be configured to prevent access to the system drive. The FTP service allows remote users to access shared files and directories. Access outside of the specific directories of shared data could provide access to system resources and compromise the system.
SV-51157r1_rule WN12-GE-000004-DC CCI-002235 HIGH Only administrators responsible for the domain controller must have Administrator rights on the system. An account that does not have Administrator duties must not have Administrator rights. Such rights would allow the account to bypass or modify required security restrictions on that machine and make it vulnerable to attack. System administrators must log on to systems only using accounts with the minimum level of authority necessary. Standard user accounts must not be members of the built-in Administrators group.
SV-52859r2_rule WN12-00-000013 CCI-000366 LOW Security configuration tools or equivalent processes must be used to configure and maintain platforms for security compliance. Security configuration tools such as Group Policies and Security Templates allow system administrators to consolidate security-related system settings into a single configuration file. These settings can then be applied consistently to any number of Windows machines.
SV-52213r1_rule WN12-GE-000012 CCI-000213 LOW Nonadministrative user accounts or groups must only have print permissions on printer shares. Windows shares are a means by which files, folders, printers, and other resources can be published for network users to access. Improper configuration can permit access to devices and data beyond a user's need.
SV-52860r1_rule WN12-SO-000034 CCI-001133 LOW Users must be forcibly disconnected when their logon hours expire. Users must not be permitted to remain logged on to the network after they have exceeded their permitted logon hours. In many cases, this indicates that a user forgot to log off before leaving for the day. However, it may also indicate that a user is attempting unauthorized access at a time when the system may be less closely monitored. Forcibly disconnecting users when logon hours expire protects critical and sensitive network data from exposure to unauthorized personnel with physical access to the computer.
SV-52861r2_rule WN12-SO-000030 CCI-000197 MEDIUM Unencrypted passwords must not be sent to third-party SMB Servers. Some non-Microsoft SMB servers only support unencrypted (plain text) password authentication. Sending plain text passwords across the network, when authenticating to an SMB server, reduces the overall security of the environment. Check with the vendor of the SMB server to see if there is a way to support encrypted password authentication.
SV-52107r2_rule WN12-SO-000036 CCI-000366 MEDIUM Automatic logons must be disabled. Allowing a system to automatically log on when the machine is booted could give access to any unauthorized individual who restarts the computer. Automatic logon with administrator privileges would give full access to an unauthorized individual.If the DefaultName or DefaultDomainName in the same registry path contain an administrator account name and the DefaultPassword contains a value, this is a CAT I finding.
SV-52863r2_rule WN12-AC-000008 CCI-000192 MEDIUM The built-in Windows password complexity policy must be enabled. The use of complex passwords increases their strength against attack. The built-in Windows password complexity policy requires passwords to contain at least 3 of the 4 types of characters (numbers, upper- and lower-case letters, and special characters), as well as preventing the inclusion of user names or parts of.
SV-52214r2_rule WN12-SO-000089 CCI-001812 LOW The print driver installation privilege must be restricted to administrators. Allowing users to install drivers can introduce malware or cause the instability of a system. Print driver installation should be restricted to administrators.
SV-52864r3_rule WN12-RG-000004 CCI-002235 HIGH Anonymous access to the registry must be restricted. The registry is integral to the function, security, and stability of the Windows system. Some processes may require anonymous access to the registry. This must be limited to properly protect the system.
SV-52865r1_rule WN12-SO-000067 CCI-000366 HIGH The LanMan authentication level must be set to send NTLMv2 response only, and to refuse LM and NTLM. The Kerberos v5 authentication protocol is the default for authentication of users who are logging on to domain accounts. NTLM, which is less secure, is retained in later Windows versions for compatibility with clients and servers that are running earlier versions of Windows or applications that still use it. It is also used to authenticate logons to stand-alone computers that are running later versions.
SV-52866r1_rule WN12-SO-000019 CCI-000366 MEDIUM The Ctrl+Alt+Del security attention sequence for logons must be enabled. Disabling the Ctrl+Alt+Del security attention sequence can compromise system security. Because only Windows responds to the Ctrl+Alt+Del security sequence, a user can be assured that any passwords entered following that sequence are sent only to Windows. If the sequence requirement is eliminated, malicious programs can request and receive a user's Windows password. Disabling this sequence also suppresses a custom logon banner.
SV-51144r1_rule WN12-UR-000017-DC CCI-000213 MEDIUM The Deny access to this computer from the network user right on domain controllers must be configured to prevent unauthenticated access. Inappropriate granting of user rights can provide system, administrative, and other high-level capabilities. The "Deny access to this computer from the network" user right defines the accounts that are prevented from logging on from the network. The Guests group must be assigned this right to prevent unauthenticated access.
SV-52867r2_rule WN12-SO-000027 CCI-000366 MEDIUM The Smart Card removal option must be configured to Force Logoff or Lock Workstation. Unattended systems are susceptible to unauthorized use and must be locked. Configuring a system to lock when a smart card is removed will ensure the system is inaccessible when unattended.
SV-52870r2_rule WN12-SO-000033 CCI-002418 MEDIUM The Windows SMB server must perform SMB packet signing when possible. The server message block (SMB) protocol provides the basis for many network operations. Digitally signed SMB packets aid in preventing man-in-the-middle attacks. If this policy is enabled, the SMB server will negotiate SMB packet signing as requested by the client.
SV-52871r3_rule WN12-SO-000013 CCI-002418 MEDIUM Outgoing secure channel traffic must be encrypted when possible. Requests sent on the secure channel are authenticated, and sensitive information (such as passwords) is encrypted, but not all information is encrypted. If this policy is enabled, outgoing secure channel traffic will be encrypted.
SV-52872r3_rule WN12-SO-000014 CCI-002418 MEDIUM Outgoing secure channel traffic must be signed when possible. Requests sent on the secure channel are authenticated, and sensitive information (such as passwords) is encrypted, but the channel is not integrity checked. If this policy is enabled, outgoing secure channel traffic will be signed.
SV-52873r1_rule WN12-SO-000015 CCI-000366 LOW The computer account password must not be prevented from being reset. Computer account passwords are changed automatically on a regular basis. Disabling automatic password changes can make the system more vulnerable to malicious access. Frequent password changes can be a significant safeguard for your system. A new password for the computer account will be generated every 30 days.
SV-52874r2_rule WN12-SO-000029 CCI-002418 MEDIUM The Windows SMB client must be enabled to perform SMB packet signing when possible. The server message block (SMB) protocol provides the basis for many network operations. If this policy is enabled, the SMB client will request packet signing when communicating with an SMB server that is enabled or required to perform SMB packet signing.
SV-52156r2_rule WN12-00-000009-01 CCI-000366 MEDIUM Members of the Backup Operators group must be documented. Backup Operators are able to read and write to any file in the system, regardless of the rights assigned to it. Backup and restore rights permit users to circumvent the file access restrictions present on NTFS disk drives for backup and restore purposes. Visibility of members of the Backup Operators group must be maintained.
SV-52875r1_rule WN12-SO-000011 CCI-000366 MEDIUM Ejection of removable NTFS media must be restricted to Administrators. Removable hard drives, if they are not properly configured, can be formatted and ejected by users who are not members of the Administrators Group. Formatting and ejecting removable NTFS media must only be done by administrators.
SV-52876r1_rule WN12-SO-000025 CCI-000366 LOW Users must be warned in advance of their passwords expiring. Creating strong passwords that can be remembered by users requires some thought. By giving the user advance warning, the user has time to construct a sufficiently strong password. This setting configures the system to display a warning to users telling them how many days are left before their password expires.
SV-52877r1_rule WN12-SO-000076 CCI-000366 LOW The default permissions of global system objects must be increased. Windows systems maintain a global list of shared system resources such as DOS device names, mutexes, and semaphores. Each type of object is created with a default DACL that specifies who can access the objects with what permissions. If this policy is enabled, the default DACL is stronger, allowing nonadministrative users to read shared objects, but not modify shared objects that they did not create.
SV-52878r3_rule WN12-SO-000031 CCI-001133 LOW The amount of idle time required before suspending a session must be properly set. Open sessions can increase the avenues of attack on a system. This setting is used to control when a computer disconnects an inactive SMB session. If client activity resumes, the session is automatically reestablished. This protects critical and sensitive network data from exposure to unauthorized personnel with physical access to the computer.
SV-52880r1_rule WN12-AC-000009 CCI-000196 HIGH Reversible password encryption must be disabled. Storing passwords using reversible encryption is essentially the same as storing clear-text versions of the passwords. For this reason, this policy must never be enabled.
SV-52879r2_rule WN12-CC-000074 CCI-001764 HIGH Autoplay must be disabled for all drives. Allowing Autoplay to execute may introduce malicious code to a system. Autoplay begins reading from a drive as soon media is inserted into the drive. As a result, the setup file of programs or music on audio media may start. By default, Autoplay is disabled on removable drives, such as the floppy disk drive (but not the CD-ROM drive) and on network drives. Enabling this policy disables Autoplay on all drives.
SV-51160r2_rule WN12-AC-000010-DC CCI-000366 MEDIUM Kerberos user logon restrictions must be enforced. This policy setting determines whether the Kerberos Key Distribution Center (KDC) validates every request for a session ticket against the user rights policy of the target computer. The policy is enabled by default which is the most secure setting for validating access to target resources is not circumvented.ECSC-1
SV-51162r2_rule WN12-AC-000011-DC CCI-000366 MEDIUM The Kerberos service ticket maximum lifetime must be limited to 600 minutes or less. This setting determines the maximum amount of time (in minutes) that a granted session ticket can be used to access a particular service. Session tickets are used only to authenticate new connections with servers. Ongoing operations are not interrupted if the session ticket used to authenticate the connection expires during the connection.ECSC-1
SV-51164r2_rule WN12-AC-000012-DC CCI-000366 MEDIUM The Kerberos user ticket lifetime must be limited to 10 hours or less. In Kerberos, there are 2 types of tickets: Ticket Granting Tickets (TGTs) and Service Tickets. Kerberos tickets have a limited lifetime so the time an attacker has to implement an attack is limited. This policy controls how long TGTs can be renewed. With Kerberos, the user's initial authentication to the domain controller results in a TGT which is then used to request Service Tickets to resources. Upon startup, each computer gets a TGT before requesting a service ticket to the domain controller and any other computers it needs to access. For services that startup under a specified user account, users must always get a TGT first, then get Service Tickets to all computers and services accessed.ECSC-1
SV-51166r2_rule WN12-AC-000013-DC CCI-000366 MEDIUM The Kerberos policy user ticket renewal maximum lifetime must be limited to 7 days or less. This setting determines the period of time (in days) during which a user's TGT may be renewed. This security configuration limits the amount of time an attacker has to crack the TGT and gain access.ECSC-1
SV-51168r3_rule WN12-AC-000014-DC CCI-001941 MEDIUM The computer clock synchronization tolerance must be limited to 5 minutes or less. This setting determines the maximum time difference (in minutes) that Kerberos will tolerate between the time on a client's clock and the time on a server's clock while still considering the two clocks synchronous. In order to prevent replay attacks, Kerberos uses timestamps as part of its protocol definition. For timestamps to work properly, the clocks of the client and the server need to be in sync as much as possible.
SV-52215r2_rule WN12-GE-000017 CCI-000366 MEDIUM System files must be monitored for unauthorized changes. Monitoring system files for changes against a baseline on a regular basis may help detect the possible introduction of malicious code on a system.DCSL-1
SV-52881r3_rule WN12-GE-000018 CCI-001090 MEDIUM Non system-created file shares on a system must limit access to groups that require it. Shares on a system provide network access. To prevent exposing sensitive information, where shares are necessary, permissions must be reconfigured to give the minimum access to those accounts that require it.
SV-52105r3_rule WN12-GE-000022 CCI-000366 MEDIUM Servers must have a host-based Intrusion Detection System. A properly configured host-based Intrusion Detection System provides another level of defense against unauthorized access to critical servers. With proper configuration and logging enabled, such a system can stop and/or alert for many attempts to gain unauthorized access to resources.This finding can be downgraded to a CAT III, if there is an active JIDS or firewall protecting the network.
SV-52882r1_rule WN12-SO-000050 CCI-000366 HIGH Anonymous SID/Name translation must not be allowed. Allowing anonymous SID/Name translation can provide sensitive information for accessing a system. Only authorized users must be able to perform such translations.
SV-51138r2_rule WN12-SO-000055-DC CCI-001090 HIGH Named pipes that can be accessed anonymously must be configured with limited values on domain controllers. Named pipes that can be accessed anonymously provide the potential for gaining unauthorized system access. Pipes are internal system communications processes. They are identified internally by ID numbers that vary between systems. To make access to these processes easier, these pipes are given names that do not vary between systems. This setting controls which of these pipes anonymous users may access.
SV-52883r2_rule WN12-SO-000056 CCI-001090 HIGH Unauthorized remotely accessible registry paths must not be configured. The registry is integral to the function, security, and stability of the Windows system. Some processes may require remote access to the registry. This setting controls which registry paths are accessible from a remote computer. These registry paths must be limited, as they could give unauthorized individuals access to the registry.
SV-52884r1_rule WN12-SO-000059 CCI-001090 HIGH Network shares that can be accessed anonymously must not be allowed. Anonymous access to network shares provides the potential for gaining unauthorized system access by network users. This could lead to the exposure or corruption of sensitive data.
SV-52885r1_rule WN12-CC-000059 CCI-001090 HIGH Solicited Remote Assistance must not be allowed. Remote assistance allows another user to view or take control of the local session of a user. Solicited assistance is help that is specifically requested by the local user. This may allow unauthorized parties access to the resources on the computer.
SV-52886r1_rule WN12-SO-000004 CCI-000366 HIGH Local accounts with blank passwords must be restricted to prevent access from the network. An account without a password can allow unauthorized access to a system as only the username would be required. Password policies should prevent accounts with blank passwords from existing on a system. However, if a local account with a blank password did exist, enabling this setting will prevent network access, limiting the account to local console logon only.
SV-52887r1_rule WN12-SO-000016 CCI-000366 LOW The maximum age for machine account passwords must be set to requirements. Computer account passwords are changed automatically on a regular basis. This setting controls the maximum password age that a machine account may have. This setting must be set to no more than 30 days, ensuring the machine changes its password monthly.
SV-52888r2_rule WN12-SO-000017 CCI-002418 MEDIUM The system must be configured to require a strong session key. A computer connecting to a domain controller will establish a secure channel. Requiring strong session keys enforces 128-bit encryption between systems.
SV-52889r1_rule WN12-SO-000053 CCI-002038 MEDIUM The system must be configured to prevent the storage of passwords and credentials. This setting controls the storage of passwords and credentials for network authentication on the local system. Such credentials must not be stored on the local machine, as that may lead to account compromise.
SV-52890r1_rule WN12-SO-000054 CCI-000366 MEDIUM The system must be configured to prevent anonymous users from having the same rights as the Everyone group. Access by anonymous users must be restricted. If this setting is enabled, then anonymous users have the same rights and permissions as the built-in Everyone group. Anonymous users must not have these permissions or rights.
SV-52891r1_rule WN12-SO-000060 CCI-001090 MEDIUM The system must be configured to use the Classic security model. Windows includes two network-sharing security models - Classic and Guest only. With the Classic model, local accounts must be password protected; otherwise, anyone can use guest user accounts to access shared system resources.
SV-52892r2_rule WN12-SO-000065 CCI-000196 HIGH The system must be configured to prevent the storage of the LAN Manager hash of passwords. The LAN Manager hash uses a weak encryption algorithm and there are several tools available that use this hash to retrieve account passwords. This setting controls whether or not a LAN Manager hash of the password is stored in the SAM the next time the password is changed.
SV-52893r1_rule WN12-SO-000066 CCI-001133 MEDIUM The system must be configured to force users to log off when their allowed logon hours expire. Limiting logon hours can help protect data by only allowing access during specified times. This setting controls whether or not users are forced to log off when their allowed logon hours expire. If logon hours are set for users, this must be enforced.
SV-52894r1_rule WN12-SO-000068 CCI-000366 MEDIUM The system must be configured to the required LDAP client signing level. This setting controls the signing requirements for LDAP clients. This setting must be set to Negotiate signing or Require signing, depending on the environment and type of LDAP server in use.
SV-52895r1_rule WN12-SO-000069 CCI-000366 MEDIUM The system must be configured to meet the minimum session security requirement for NTLM SSP-based clients. Microsoft has implemented a variety of security support providers for use with RPC sessions. All of the options must be enabled to ensure the maximum security level.
SV-52896r2_rule WN12-SO-000074 CCI-002450 MEDIUM The system must be configured to use FIPS-compliant algorithms for encryption, hashing, and signing. This setting ensures that the system uses algorithms that are FIPS-compliant for encryption, hashing, and signing. FIPS-compliant algorithms meet specific standards established by the U.S. Government and must be the algorithms used for all OS encryption functions.
SV-52897r1_rule WN12-SO-000075 CCI-000366 MEDIUM The system must be configured to require case insensitivity for non-Windows subsystems. This setting controls the behavior of non-Windows subsystems when dealing with the case of arguments or commands. Case sensitivity could lead to the access of files or commands that must be restricted. To prevent this from happening, case insensitivity restrictions must be required.
SV-52216r2_rule WN12-CC-000131 CCI-000054 MEDIUM Remote Desktop Services must limit users to one remote session. Allowing multiple Remote Desktop Services sessions could consume resources. There is also potential to make a secondary connection to a system with compromised credentials.ECLO-1, ECLO-2
SV-52898r1_rule WN12-CC-000099 CCI-002038 MEDIUM Remote Desktop Services must always prompt a client for passwords upon connection. This setting controls the ability of users to supply passwords automatically as part of their remote desktop connection. Disabling this setting would allow anyone to use the stored credentials in a connection item to connect to the terminal server.
SV-52899r2_rule WN12-CC-000100 CCI-000068 MEDIUM Remote Desktop Services must be configured with the client connection encryption set to the required level. Remote connections must be encrypted to prevent interception of data or sensitive information. Selecting "High Level" will ensure encryption of Remote Desktop Services sessions in both directions.
SV-52900r1_rule WN12-CC-000104 CCI-000366 MEDIUM Remote Desktop Services must be configured to use session-specific temporary folders. If a communal temporary folder is used for remote desktop sessions, it might be possible for users to access other users' temporary folders. If this setting is enabled, only one temporary folder is used for all remote desktop sessions. Per session temporary folders must be established.
SV-52901r1_rule WN12-CC-000103 CCI-000366 MEDIUM Remote Desktop Services must delete temporary folders when a session is terminated. Remote desktop session temporary folders must always be deleted after a session is over to prevent hard disk clutter and potential leakage of information. This setting controls the deletion of the temporary folders when the session is terminated.
SV-52906r1_rule WN12-CC-000029 CCI-000366 MEDIUM Group Policies must be refreshed in the background if the user is logged on. If this setting is enabled, then Group Policy settings are not refreshed while a user is currently logged on. This could lead to instances when a user does not have the latest changes to a policy applied and is therefore operating in an insecure context.
SV-52917r1_rule WN12-CC-000058 CCI-001090 MEDIUM The system must be configured to prevent unsolicited remote assistance offers. Remote assistance allows another user to view or take control of the local session of a user. Unsolicited remote assistance is help that is offered by the remote user. This may allow unauthorized parties access to the resources on the computer.
SV-52919r3_rule WN12-CC-000069 CCI-001891 LOW The time service must synchronize with an appropriate DoD time source. The Windows Time Service controls time synchronization settings. Time synchronization is essential for authentication and auditing purposes. If the Windows Time Service is used, it must synchronize with a secure, authorized time source. Domain-joined systems are automatically configured to synchronize with domain controllers. If an NTP server is configured, it must synchronize with a secure, authorized time source.
SV-52920r1_rule WN12-SO-000045 CCI-000366 MEDIUM The system must be configured to use Safe DLL Search Mode. The default search behavior, when an application calls a function in a Dynamic Link Library (DLL), is to search the current directory, followed by the directories contained in the system's path environment variable. An unauthorized DLL, inserted into an application's working directory, could allow malicious code to be run on the system. Setting this policy value forces the system to search the %Systemroot% for the DLL before searching the current directory or the rest of the path.
SV-53130r1_rule WN12-CC-000122 CCI-001812 MEDIUM Windows Media Player must be configured to prevent automatic checking for updates. Uncontrolled system updates can introduce issues to a system. The automatic check for updates performed by Windows Media Player must be disabled to ensure a constant platform and to prevent the introduction of unknown\untested software on the system.
SV-52921r1_rule WN12-UC-000013 CCI-001812 MEDIUM Media Player must be configured to prevent automatic Codec downloads. The Windows Media Player uses software components, referred to as Codecs, to play back media files. By default, when an unknown file type is opened with the Media Player, it will search the Internet for the appropriate Codec and automatically download it. To ensure platform consistency and to protect against new vulnerabilities associated with media types, all Codecs must be installed by the System Administrator.
SV-52218r2_rule WN12-GE-000021 CCI-000381 MEDIUM Necessary services must be documented to maintain a baseline to determine if additional, unnecessary services have been added to a system. Unnecessary services increase the attack surface of a system. Some services may be run under the local System account, which generally has more permissions than required by the service. Compromising a service could allow an intruder to obtain system permissions and open the system to a variety of attacks.
SV-52922r1_rule WN12-SO-000070 CCI-000366 MEDIUM The system must be configured to meet the minimum session security requirement for NTLM SSP-based servers. Microsoft has implemented a variety of security support providers for use with RPC sessions. All of the options must be enabled to ensure the maximum security level.
SV-52923r2_rule WN12-SO-000049 CCI-000139 LOW The system must generate an audit event when the audit log reaches a percentage of full threshold. When the audit log reaches a given percent full, an audit event is written to the security log. It is recorded as a successful audit event under the category of System. This option may be especially useful if the audit logs are set to be cleared manually.
SV-52924r1_rule WN12-SO-000038 CCI-000366 LOW The system must be configured to prevent IP source routing. Configuring the system to disable IP source routing protects against spoofing.
SV-52925r1_rule WN12-SO-000039 CCI-000366 LOW The system must be configured to prevent Internet Control Message Protocol (ICMP) redirects from overriding Open Shortest Path First (OSPF) generated routes. Allowing ICMP redirect of routes can lead to traffic not being routed properly. When disabled, this forces ICMP to be routed via shortest path first.
SV-52926r1_rule WN12-SO-000044 CCI-002385 LOW The system must be configured to disable the Internet Router Discovery Protocol (IRDP). The Internet Router Discovery Protocol (IRDP) is used to detect and configure default gateway addresses on the computer. If a router is impersonated on a network, traffic could be routed through the compromised system.
SV-52927r1_rule WN12-SO-000041 CCI-002385 LOW The system must be configured to limit how often keep-alive packets are sent. This setting controls how often TCP sends a keep-alive packet in attempting to verify that an idle connection is still intact. A higher value could allow an attacker to cause a denial of service with numerous connections.
SV-52928r2_rule WN12-SO-000043 CCI-002385 LOW The system must be configured to ignore NetBIOS name release requests except from WINS servers. Configuring the system to ignore name release requests, except from WINS servers, prevents a denial of service (DoS) attack. The DoS consists of sending a NetBIOS name release request to the server for each entry in the server's cache, causing a response delay in the normal operation of the servers WINS resolution capability.
SV-51140r3_rule WN12-SO-000090-DC CCI-002418 MEDIUM Domain controllers must require LDAP access signing. Unsigned network traffic is susceptible to man in the middle attacks where an intruder captures packets between the server and the client and modifies them before forwarding them to the client. In the case of an LDAP server, this means that an attacker could cause a client to make decisions based on false records from the LDAP directory. You can lower the risk of an attacker pulling this off in a corporate network by implementing strong physical security measures to protect the network infrastructure. Furthermore, implementing Internet Protocol security (IPSec) authentication header mode (AH), which performs mutual authentication and packet integrity for Internet Protocol (IP) traffic, can make all types of man in the middle attacks extremely difficult.
SV-51141r2_rule WN12-SO-000091-DC CCI-000366 LOW Domain controllers must be configured to allow reset of machine account passwords. Enabling this setting on all domain controllers in a domain prevents domain members from changing their computer account passwords. If these passwords are weak or compromised, the inability to change them may leave these computers vulnerable.ECSC-1
SV-52929r2_rule WN12-SO-000048 CCI-002385 LOW The system must limit how many times unacknowledged TCP data is retransmitted. In a SYN flood attack, the attacker sends a continuous stream of SYN packets to a server, and the server leaves the half-open connections open until it is overwhelmed and is no longer able to respond to legitimate requests.
SV-52930r1_rule WN12-SO-000046 CCI-000366 LOW The system must be configured to have password protection take effect within a limited time frame when the screen saver becomes active. Allowing more than several seconds makes the computer vulnerable to a potential attack from someone walking up to the console to attempt to log on to the system before the lock takes effect.
SV-52931r2_rule WN12-SO-000057 CCI-001090 HIGH Unauthorized remotely accessible registry paths and sub-paths must not be configured. The registry is integral to the function, security, and stability of the Windows system. Some processes may require remote access to the registry. This setting controls which registry paths and sub-paths are accessible from a remote computer. These registry paths must be limited, as they could give unauthorized individuals access to the registry.
SV-52219r2_rule WN12-SO-000088 CCI-000381 LOW Optional Subsystems must not be permitted to operate on the system. The POSIX subsystem is an Institute of Electrical and Electronic Engineers (IEEE) standard that defines a set of operating system services. The POSIX Subsystem is required if the server supports applications that use that subsystem. The subsystem introduces a security risk relating to processes that can potentially persist across logins. That is, if a user starts a process and then logs out, there is a potential that the next user who logs in to the system could access the previous users process. This is dangerous because the process started by the first user may retain that users system privileges, and anything the second user does with that process will be performed with the privileges of the first user.HKECSC-1
SV-52932r2_rule WN12-CC-000130 CCI-001453 MEDIUM The Remote Desktop Session Host must require secure RPC communications. Allowing unsecure RPC communication exposes the system to man-in-the-middle attacks and data disclosure attacks. A man-in-the-middle attack occurs when an intruder captures packets between a client and server and modifies them before allowing the packets to be exchanged. Usually the attacker will modify the information in the packets in an attempt to cause either the client or server to reveal sensitive information.
SV-52933r1_rule WN12-CC-000028 CCI-000366 MEDIUM Group Policy objects must be reprocessed even if they have not changed. Enabling this setting and then selecting the "Process even if the Group Policy objects have not changed" option ensures that the policies will be reprocessed even if none have been changed. This way, any unauthorized changes are forced to match the domain-based group policy settings again.
SV-52934r2_rule WN12-SO-000012 CCI-002418 MEDIUM Outgoing secure channel traffic must be encrypted or signed. Requests sent on the secure channel are authenticated, and sensitive information (such as passwords) is encrypted, but not all information is encrypted. If this policy is enabled, outgoing secure channel traffic will be encrypted and signed.
SV-52935r2_rule WN12-SO-000028 CCI-002418 MEDIUM The Windows SMB client must be configured to always perform SMB packet signing. The server message block (SMB) protocol provides the basis for many network operations. Digitally signed SMB packets aid in preventing man-in-the-middle attacks. If this policy is enabled, the SMB client will only communicate with an SMB server that performs SMB packet signing.
SV-52936r2_rule WN12-SO-000032 CCI-002418 MEDIUM The Windows SMB server must be configured to always perform SMB packet signing. The server message block (SMB) protocol provides the basis for many network operations. Digitally signed SMB packets aid in preventing man-in-the-middle attacks. If this policy is enabled, the SMB server will only communicate with an SMB client that performs SMB packet signing.
SV-52937r1_rule WN12-SO-000058 CCI-001090 HIGH Anonymous access to Named Pipes and Shares must be restricted. Allowing anonymous access to named pipes or shares provides the potential for unauthorized system access. This setting restricts access to those defined in "Network access: Named Pipes that can be accessed anonymously" and "Network access: Shares that can be accessed anonymously", both of which must be blank under other requirements.
SV-52938r2_rule WN12-AC-000007 CCI-000205 MEDIUM Passwords must, at a minimum, be 14 characters. Information systems not protected with strong password schemes (including passwords of minimum length) provide the opportunity for anyone to crack the password, thus gaining access to the system and compromising the device, information, or the local network.
SV-52939r4_rule WN12-GE-000016 CCI-000199 MEDIUM Windows 2012/2012 R2 passwords must be configured to expire. Passwords that do not expire or are reused increase the exposure of a password with greater probability of being discovered or cracked.
SV-52940r2_rule WN12-GE-000015 CCI-000764 HIGH Windows 2012/2012 R2 accounts must be configured to require passwords. The lack of password protection enables anyone to gain access to the information system, which opens a backdoor opportunity for intruders to compromise the system as well as other resources. Accounts on a system must require passwords.
SV-51175r3_rule WN12-AD-000001-DC CCI-002235 HIGH Active Directory data files must have proper access control permissions. Improper access permissions for directory data related files could allow unauthorized users to read, modify, or delete directory data or audit trails.
SV-51180r2_rule WN12-AD-000006-DC CCI-001082 MEDIUM Data files owned by users must be on a different logical partition from the directory server data files. When directory service data files, especially for directories used for identification, authentication, or authorization, reside on the same logical partition as user-owned files, the directory service data may be more vulnerable to unauthorized access or other availability compromises. Directory service and user-owned data files sharing a partition may be configured with less restrictive permissions in order to allow access to the user data. The directory service may be vulnerable to a denial of service attack when user-owned files on a common partition are expanded to an extent preventing the directory service from acquiring more space for directory or audit data.DCSP-1
SV-51181r2_rule WN12-AD-000007-DC CCI-001891 MEDIUM Time synchronization must be enabled on the domain controller. When a directory service using multi-master replication (such as AD) executes on computers that do not have synchronized time, directory data may be corrupted or updated invalidly. The lack of synchronized time could lead to audit log data that is misleading, inconclusive, or unusable. In cases of intrusion this may invalidate the audit data as a source of forensic evidence in an incident investigation. In AD, the lack of synchronized time could prevent clients from logging on or accessing server resources as a result of Kerberos requirements related to time variance.ECTM-1, ECTM-2
SV-51182r3_rule WN12-AD-000008-DC CCI-000366 LOW The time synchronization tool must be configured to enable logging of time source switching. When a time synchronization tool executes, it may switch between time sources according to network or server contention. If switches between time sources are not logged, it may be difficult or impossible to detect malicious activity or availability problems.ECTM-1, ECTM-2
SV-51183r2_rule WN12-AD-000009-DC CCI-001082 MEDIUM The directory server supporting (directly or indirectly) system access or resource authorization must run on a machine dedicated to that function. Executing application servers on the same host machine with a directory server may substantially weaken the security of the directory server. Web or database server applications usually require the addition of many programs and accounts increasing the attack surface of the computer. Some applications require the addition of privileged accounts providing potential sources of compromise. Some applications (such as MS Exchange) may require the use of network ports or services conflicting with the directory server. In this case, non-standard ports might be selected and this could interfere with intrusion detection or prevention services.DCSP-1
SV-51184r2_rule WN12-AD-000010-DC CCI-000366 MEDIUM Windows services that are critical for directory server operation must be configured for automatic startup. Active Directory (AD) is dependent on several Windows services. If one or more of these services is not configured for automatic startup, AD functions may be partially or completely unavailable until the services are manually started. This could result in a failure to replicate data or to support client authentication and authorization requests.ECTM-1, ECTM-2
SV-52941r1_rule WN12-SO-000018 CCI-000366 LOW The system must be configured to prevent the display of the last username on the logon screen. Displaying the username of the last logged on user provides half of the userid/password equation that an unauthorized person would need to gain access. The username of the last user to log on to a system must not be displayed.
SV-52942r3_rule WN12-00-000007 CCI-000366 MEDIUM Windows 2012/2012 R2 password for the built-in Administrator account must be changed at least annually or when a member of the administrative team leaves the organization. The longer a password is in use, the greater the opportunity for someone to gain unauthorized knowledge of the password. The password for the built-in Administrator account must be changed at least annually or when any member of the administrative team leaves the organization. Organizations that use an automated tool, such Microsoft's Local Administrator Password Solution (LAPS), on domain-joined systems can configure this to occur more frequently. LAPS will change the password every "30" days by default.
SV-53129r1_rule WN12-SO-000007 CCI-001095 MEDIUM Auditing the Access of Global System Objects must be turned off. Maintaining an audit trail of system activity logs can help identify configuration errors, troubleshoot service disruptions, and analyze compromises that have occurred, as well as detect attacks. Audit logs are necessary to provide a trail of evidence in case the system or network is compromised. Collecting this data is essential for analyzing the security of information assets and detecting signs of suspicious and unexpected behavior. This setting prevents the system from setting up a default system access control list for certain system objects, which could create a very large number of security events, filling the security log in Windows and making it difficult to identify actual issues.
SV-52943r1_rule WN12-SO-000008 CCI-001095 MEDIUM Auditing of Backup and Restore Privileges must be turned off. Maintaining an audit trail of system activity logs can help identify configuration errors, troubleshoot service disruptions, and analyze compromises that have occurred, as well as detect attacks. Audit logs are necessary to provide a trail of evidence in case the system or network is compromised. Collecting this data is essential for analyzing the security of information assets and detecting signs of suspicious and unexpected behavior. This setting prevents the system from generating audit events for every file backed up or restored, which could fill the security log in Windows, making it difficult to identify actual issues.

SV-51186r2_rule WN12-AD-000012-DC CCI-000366 LOW Anonymous access to the root DSE of a non-public directory must be disabled. Allowing anonymous access to the root DSE data on a directory server provides potential attackers with a number of details about the configuration and data contents of a directory. For example, the namingContexts attribute indicates the directory space contained in the directory; the supportedLDAPVersion attribute indicates which versions of the LDAP protocol the server supports; and the supportedSASLMechanisms attribute indicates the names of supported authentication mechanisms. An attacker with this information may be able to select more precisely targeted attack tools or higher value targets.The following network controls allow the finding severity to be downgraded to not a finding since these measures lower the risk associated with anonymous access. Network hardware ports at the site are subject to 802.1x authentication or MAC address restrictions.

A PKI implementation depends on the practices established by the Certificate Authority (CA) to ensure the implementation is secure. Without proper practices, the certificates issued by a CA have limited value in authentication functions. The use of multiple CAs from separate PKI implementations results in interoperability issues. If servers and clients do not have a common set of root CA certificates, they are not able to authenticate each other.If the certificates in use are issued by a CA authorized by the Components CIO, this is a CAT II finding.IAKM-1, IAKM-2, IATS-1, IATS-2
SV-51188r2_rule WN12-AD-000014-DC CCI-001133 LOW The directory service must be configured to terminate LDAP-based network connections to the directory server after five (5) minutes of inactivity. The failure to terminate inactive network connections increases the risk of a successful attack on the directory server. The longer an established session is in progress, the more time an attacker has to hijack the session, implement a means to passively intercept data, or compromise any protections on client access. For example, if an attacker gains control of a client computer, an existing (already authenticated) session with the directory server could allow access to the directory. The lack of confidentiality protection in LDAP-based sessions increases exposure to this vulnerability.

SV-51177r5_rule WN12-AD-000003-DC CCI-002235 HIGH Active Directory Group Policy objects must have proper access control permissions. When directory service database objects do not have appropriate access control permissions, it may be possible for malicious users to create, read, update, or delete the objects and degrade or destroy the integrity of the data. When the directory service is used for identification, authentication, or authorization functions, a compromise of the database objects could lead to a compromise of all systems relying on the directory service. For Active Directory (AD), the Group Policy objects require special attention. In a distributed administration model (i.e., help desk), Group Policy objects are more likely to have access permissions changed from the secure defaults. If inappropriate access permissions are defined for Group Policy Objects, this could allow an intruder to change the security policy applied to all domain client computers (workstations and servers).

If a flaw in an application is exploited while running as a privileged user, the entire system could be compromised. Web browsers and email are common attack vectors for introducing malicious code and must not be run with an administrative account. Since administrative accounts may generally change or work around technical restrictions for running a web browser or other applications, it is essential that policy requires administrative accounts to not access the Internet or use applications, such as email. The policy should define specific exceptions for local service administration. These exceptions may include HTTP(S)-based tools that are used for the administration of the local system, services, or attached devices. Technical means such as application whitelisting can be used to enforce the policy to ensure compliance.

If the private key is discovered, an attacker can use the key to authenticate as an authorized user and gain access to the network infrastructure. The cornerstone of the PKI is the private key used to encrypt or digitally sign information. If the private key is stolen, this will lead to the compromise of the authentication and non-repudiation gained through PKI because the attacker can use the private key to digitally sign documents and pretend to be the authorized user. Both the holders of a digital certificate and the issuing authority must protect the computers, storage devices, or whatever they use to keep the private keys.
SV-72051r1_rule WN12-00-000019 CCI-002420 MEDIUM Protection methods such as TLS, encrypted VPNs, or IPSEC must be implemented if the data owner has a strict requirement for ensuring data integrity and confidentiality is maintained at every step of the data transfer and handling process. Information can be either unintentionally or maliciously disclosed or modified during preparation for transmission, for example, during aggregation, at protocol transformation points, and during packing/unpacking. These unauthorized disclosures or modifications compromise the confidentiality or integrity of the information. Ensuring the confidentiality of transmitted information requires the operating system to take measures in preparing information for transmission. This can be accomplished via access control and encryption. Use of this requirement will be limited to situations where the data owner has a strict requirement for ensuring data integrity and confidentiality is maintained at every step of the data transfer and handling process. When transmitting data, operating systems need to support transmission protection mechanisms such as TLS, encrypted VPNs, or IPSEC.
SV-72055r1_rule WN12-00-000020 CCI-001199 MEDIUM Systems requiring data at rest protections must employ cryptographic mechanisms to prevent unauthorized disclosure and modification of the information at rest. This requirement addresses protection of user-generated data, as well as operating system-specific configuration data. Organizations may choose to employ different mechanisms to achieve confidentiality and integrity protections, as appropriate, in accordance with the security category and/or classification of the information. Selection of a cryptographic mechanism is based on the need to protect the integrity of organizational information. The strength of the mechanism is commensurate with the security category and/or classification of the information. Organizations have the flexibility to either encrypt all information on storage devices (i.e., full disk encryption) or encrypt specific data structures (e.g., files, records, or fields).
SV-72063r2_rule WN12-GE-000056 CCI-000016 MEDIUM Windows 2012 / 2012 R2 must automatically remove or disable temporary user accounts after 72 hours. If temporary user accounts remain active when no longer needed or for an excessive period, these accounts may be used to gain unauthorized access. To mitigate this risk, automated termination of all temporary accounts must be set upon account creation. Temporary accounts are established as part of normal account activation procedures when there is a need for short-term accounts without the demand for immediacy in account activation. If temporary accounts are used, the operating system must be configured to automatically terminate these types of accounts after a DoD-defined time period of 72 hours. To address access requirements, many operating systems may be integrated with enterprise-level authentication/access mechanisms that meet or exceed access control policy requirements.
SV-72065r3_rule WN12-GE-000057 CCI-001682 MEDIUM Windows 2012 / 2012 R2 must automatically remove or disable emergency accounts after the crisis is resolved or within 72 hours. Emergency administrator accounts are privileged accounts which are established in response to crisis situations where the need for rapid account activation is required. Therefore, emergency account activation may bypass normal account authorization processes. If these accounts are automatically disabled, system maintenance during emergencies may not be possible, thus adversely affecting system availability. Emergency administrator accounts are different from infrequently used accounts (i.e., local logon accounts used by system administrators when network or normal logon/access is not available). Infrequently used accounts are not subject to automatic termination dates. Emergency accounts are accounts created in response to crisis situations, usually for use by maintenance personnel. The automatic expiration or disabling time period may be extended as needed until the crisis is resolved; however, it must not be extended indefinitely. A permanent account should be established for privileged users who need long-term maintenance accounts. To address access requirements, many operating systems can be integrated with enterprise-level authentication/access mechanisms that meet or exceed access control policy requirements.
SV-72133r1_rule WN12-AU-000203-02 CCI-001851 MEDIUM The operating system must, at a minimum, off-load audit records of interconnected systems in real time and off-load standalone systems weekly. Protection of log data includes assuring the log data is not accidentally lost or deleted. Audit information stored in one location is vulnerable to accidental or incidental deletion or alteration.
SV-72135r2_rule WN12-AU-000213 CCI-001494 MEDIUM Event Viewer must be protected from unauthorized modification and deletion. Protecting audit information also includes identifying and protecting the tools used to view and manipulate log data. Therefore, protecting audit tools is necessary to prevent unauthorized operation on audit information. Operating systems providing tools to interface with audit information will leverage user permissions and roles identifying the user accessing the tools and the corresponding rights the user enjoys in order to make access decisions regarding the modification or deletion of audit tools.
SV-87391r1_rule WN12-CC-000150 CCI-000381 MEDIUM WDigest Authentication must be disabled. When the WDigest Authentication protocol is enabled, plain text passwords are stored in the Local Security Authority Subsystem Service (LSASS) exposing them to theft. This setting will prevent WDigest from storing credentials in memory.
SV-88193r2_rule WN12-00-000170 CCI-000381 MEDIUM The Server Message Block (SMB) v1 protocol must be disabled on the SMB server. SMBv1 is a legacy protocol that uses the MD5 algorithm as part of SMB. MD5 is known to be vulnerable to a number of attacks such as collision and preimage attacks as well as not being FIPS compliant. Disabling SMBv1 support may prevent access to file or print sharing resources with systems or devices that only support SMBv1. File shares and print services hosted on Windows Server 2003 are an example, however Windows Server 2003 is no longer a supported operating system. Some older network attached devices may only support SMBv1.

SV-90603r1_rule WN12-00-000190 CCI-000366 MEDIUM Orphaned security identifiers (SIDs) must be removed from user rights on Windows 2012 / 2012 R2. Accounts or groups given rights on a system may show up as unresolved SIDs for various reasons including deletion of the accounts or groups. If the account or group objects are reanimated, there is a potential they may still have rights no longer intended. Valid domain accounts or groups may also show up as unresolved SIDs if a connection to the domain cannot be established for some reason.

SV-95179r1_rule WN12-00-000200 CCI-000366 MEDIUM Windows PowerShell must be updated to a version that supports script block logging on Windows 2012/2012 R2. Later versions of Windows PowerShell provide additional security and advanced logging features that can provide greater detail when malware has been run on a system. PowerShell 5.x includes the advanced logging features. PowerShell 4.0 with the addition of patch KB3000850 on Windows 2012 R2 or KB3119938 on Windows 2012 adds advanced logging features. PowerShell is updated with the installation of the corresponding version of the Windows Management Framework (WMF). Updating to a later PowerShell version may have compatibility issues with some applications. The following links should be reviewed and updates tested before applying to a production environment.

SV-101879r1_rule WN12-AD-000015-DC CCI-000366 MEDIUM The password for the krbtgt account on a domain must be reset at least every 180 days. The krbtgt account acts as a service account for the Kerberos Key Distribution Center (KDC) service. The account and password are created when a domain is created and the password is typically not changed. If the krbtgt account is compromised, attackers can create valid Kerberos Ticket Granting Tickets (TGT). The password must be changed twice to effectively remove the password history. Changing once, waiting for replication to complete and changing again reduces the risk of issues. Changing twice in rapid succession forces clients to re-authenticate (including application services) but is desired if a compromise is suspected.
