Vuln Rule Version CCI Severity Title Description
SV-53189r1_rule WN12-GE-000001 CCI-002605 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 leaves them subject to exploitation. Systems must be maintained at a service pack level supported by the vendor with new security updates.VIVM-1
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.ECSC-1
SV-52843r1_rule WN12-GE-000005 CCI-000213 HIGH Local volumes must be formatted using NTFS. The ability to set access permissions and auditing is critical to maintaining the security and proper access controls of a system. To support this, volumes must be formatted using the NTFS file system.ECCD-1, ECCD-2
SV-52845r1_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.ECWM-1
SV-52846r1_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, storing encrypted copies of users' passwords on workstations does not always have the same physical protection required for domain controllers. If a workstation 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.ECSC-1
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.ECSC-1, PRNK-1
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.ECLO-1, ECLO-2
SV-52849r1_rule WN12-AC-000003 CCI-000044 MEDIUM The period of time before the bad logon counter is reset must meet minimum requirements. 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.ECLO-1, ECLO-2
SV-52850r1_rule WN12-AC-000001 CCI-002238 MEDIUM The lockout duration must be configured to require an administrator to unlock an account. 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. A value of 0 will require an administrator to unlock the account.ECLO-1, ECLO-2
SV-52108r1_rule WN12-UR-000003 CCI-002235 HIGH Unauthorized accounts must not have the Act as part of the operating system user right. 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.If an application requires this user right, this can be downgraded to a CAT III if the following conditions are met: Vendor documentation must support the requirement for having the user right. The requirement must be documented with the IAO. The application account must meet requirements for application account passwords, such as length (V-36661) and required changes frequency (V-36662).ECLP-1
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.IAIA-1, IAIA-2
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.IAIA-1, IAIA-2
SV-52853r1_rule WN12-AC-000004 CCI-000200 MEDIUM The password uniqueness must meet minimum requirements. 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.IAIA-1, IAIA-2
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.IAAC-1
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.ECSC-1
SV-52861r1_rule WN12-SO-000030 CCI-000197 MEDIUM Unencrypted passwords must not be sent to a third-party SMB Server. 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.ECCT-1, ECCT-2
SV-52107r1_rule WN12-SO-000036 CCI-002038 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.ECSC-1
SV-52863r1_rule WN12-AC-000008 CCI-000192 LOW The built-in Microsoft password complexity filter must be enabled. The use of complex passwords increases their strength against guessing and brute-force attacks. This setting configures the system to verify that newly created passwords conform to the Windows password complexity policy.IAIA-1, IAIA-2
SV-52214r1_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. This capability should be restricted to administrators.ECLP-1
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.IAIA-1, IAIA-2
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.ECSC-1
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.ECLP-1
SV-52867r1_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.ECSC-1
SV-52868r1_rule WN12-SO-000072 CCI-000366 LOW The Recovery Console SET command must be disabled. The Recovery Console SET command allows environment variables to be set in the Recovery Console. This permits access to all drives and folders and the copying of files to removable media, which could expose sensitive information.ECCD-1, ECCD-2
SV-52869r1_rule WN12-SO-000071 CCI-002038 HIGH The Recovery Console option must be set to prevent automatic logon to the system. If this option is enabled, the Recovery Console does not require a password and automatically logs on to the system. This could allow unauthorized administrative access to the system.ECCD-1, ECCD-2
SV-52870r1_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.ECSC-1
SV-52871r1_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.If the value for Domain Member: Digitally encrypt or sign secure channel data (always) is set to Enabled, this would not be a finding.ECCT-1, ECCT-2
SV-52872r1_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.If the value for Domain Member: Digitally encrypt or sign secure channel data (always) is set to Enabled, this would not be a finding.DCNR-1
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.IAIA-1, IAIA-2
SV-52874r1_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.ECSC-1
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.ECLP-1
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.ECSC-1
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.ECSC-1
SV-52878r1_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.ECSC-1
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.IAIA-1, IAIA-2
SV-52879r1_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.ECSC-1
SV-51160r1_rule WN12-AC-000010-DC 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-51162r1_rule WN12-AC-000011-DC 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-51164r1_rule WN12-AC-000012-DC 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-51166r1_rule WN12-AC-000013-DC 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-51168r1_rule WN12-AC-000014-DC 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.ECSC-1
SV-51138r1_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.ECSC-1
SV-52883r1_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.ECCD-1, ECCD-2
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.ECCD-1, ECCD-2
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.ECSC-1
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.IAIA-1
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.IAIA-1, IAIA-2
SV-52888r1_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. ECSC-1
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.ECSC-1
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.ECCD-1, ECCD-2, ECLP-1, ECSC-1
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.ECLO-1
SV-52892r1_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. ECSC-1, IAIA-1, IAIA-2
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.ECSC-1
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.ECSC-1
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.ECCT-1, ECCT-2
SV-52896r1_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.Clients with this setting enabled will not be able to communicate via digitally encrypted or signed protocols with servers that do not support these algorithms. Both the browser and web server must be configured to use TLS, or the browser will not be able to connect to a secure site.ECCT-1, ECCT-2
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.ECSC-1
SV-52216r1_rule WN12-CC-000131 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.IAIA-1, IAIA-2
SV-52899r1_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.ECCT-1, ECCT-2
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.ECRC-1
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.ECRC-1
SV-52902r1_rule WN12-CC-000102 CCI-001133 MEDIUM Remote Desktop Services must be configured to set a time limit for disconnected sessions. This setting controls how long a session will remain open if it is unexpectedly terminated. Such sessions use system resources and must be terminated as soon as possible.ECSC-1
SV-52903r1_rule WN12-CC-000101 CCI-001133 MEDIUM Remote Desktop Services must be configured to disconnect an idle session after the specified time period. This setting controls how long a session may be idle before it is automatically disconnected from the server. Users must disconnect if they plan on being away from their terminals for extended periods of time. Idle sessions must be disconnected after 15 minutes.ECSC-1
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.ECSC-1
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.ECSC-1
SV-52918r1_rule WN12-CC-000046 CCI-000366 MEDIUM The system must be configured to prevent automatic forwarding of error information. This setting controls the reporting of errors to Microsoft and, if defined, a corporate error reporting site. This does not interfere with the reporting of errors to the local user. Since the contents of memory are included in this error report, sensitive information may be transmitted to Microsoft. This feature must be disabled to prevent the release of such information.ECSC-1
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.ECSC-1
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.DCSL-1
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.ECCT-1, ECCT-2
SV-52923r1_rule WN12-SO-000049 CCI-001855 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.

SV-52928r1_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.ECSC-1
SV-51140r1_rule WN12-SO-000090-DC 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.ECSC-1
SV-51141r1_rule WN12-SO-000091-DC 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.

These registry paths must be limited, as they could give unauthorized individuals access to the registry.ECCD-1, ECCD-2
SV-52219r1_rule WN12-SO-000088 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-52932r1_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. ECSC-1
