Vuln Rule Version CCI Severity Title Description
SV-32240r1_rule 1.001 CCI-000366 MEDIUM The Automated Information System (AIS) will be physically secured in an access controlled area. 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 of the AIS is the first line protection of any system.System AdministratorInformation Assurance Officer
SV-32241r2_rule 1.008 CCI-000764 MEDIUM Shared user accounts must not be permitted on the system. Shared accounts (accounts where two or more people log on 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.System AdministratorInformation Assurance Officer
SV-32242r3_rule 2.005 CCI-000366 HIGH Systems must be at supported service pack (SP) or release levels. Systems at unsupported service packs or releases will not receive security updates for new vulnerabilities and leaves them subject to exploitation. Systems must be maintained at a service pack level supported by the vendor with new security updates.HKSystem Administrator
SV-32244r4_rule WIN00-000100 CCI-000366 HIGH The Windows 2008 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.System Administrator
SV-32280r1_rule 3.007 CCI-000366 LOW The shutdown option will 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 systems Security event log.HKSystem Administrator
SV-32245r1_rule 1.013 CCI-000366 LOW System information backups will be created, updated, and protected. Recovery of a damaged or compromised system in a timely basis is difficult without a system information backup. A system backup will usually include sensitive information such as user accounts that could be used in an attack. As a valuable system resource, the system backup should be protected and stored in a physically secure location.System AdministratorInformation Assurance Officer
SV-32246r2_rule 2.001 CCI-000162 MEDIUM Permissions for event logs must conform to minimum requirements. 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. Event logs may be susceptible to tampering if proper permissions are not applied.System AdministratorInformation Assurance Officer
SV-32248r1_rule 2.008 CCI-000213 HIGH Local volumes will be formatted using NTFS. This is a category 1 finding because the ability to set access permissions and audit critical directories and files is only available by using the NTFS file system. The capability to assign access permissions to file objects is a DoD policy requirement. trueSystem AdministratorInformation Assurance Officer
SV-32281r5_rule 3.011 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.System AdministratorInformation Assurance Officer
SV-32282r3_rule 3.013 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.HKSystem Administrator
SV-32283r1_rule 3.018 CCI-001090 HIGH Anonymous enumeration of shares will be restricted. This is a Category 1 finding because it allows anonymous logon users (null session connections) to list all account names and enumerate all shared resources, thus providing a map of potential points to attack the system. By default, Windows allows anonymous users to list account names and enumerate share names.trueIn a mixed Windows environment, this setting may cause systems with down-level operating systems to fail to authenticate, may prevent their users from changing their passwords, and may cause problems with managing printers and spools. In domains supporting Exchange 2003 servers and versions of Outlook earlier than Outlook 2003, the setting “Network access: Do not allow anonymous enumeration of SAM accounts and shares” should be set to “Disabled” on the Domain Controller Group Policy to allow Outlook to anonymously query the global catalog service.System AdministratorInformation Assurance Officer
SV-32284r2_rule 4.002 CCI-000044 MEDIUM The system must lockout accounts after 3 invalid logon attempts within a specified time period. 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 should be reasonably small to minimize the possibility of a successful password attack, while allowing for honest errors made during a normal user logon.HKSystem Administrator
SV-32285r3_rule 4.003 CCI-000044 MEDIUM The reset period for the account lockout counter must be configured to 15 minutes or greater on Windows 2008 R2. 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.HKSystem Administrator
SV-32286r3_rule 4.004 CCI-002238 MEDIUM Windows 2008 R2 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.HKSystem Administrator
SV-32287r2_rule WINUR-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 ISSO. Passwords for accounts with this user right must be protected as highly privileged accounts. The application account must meet requirements for application account passwords, such as length and required changes frequency (V-14271).System AdministratorInformation Assurance Officer
SV-32288r2_rule 4.011 CCI-000199 MEDIUM The maximum password age must be configured to 60 days or less. The longer passwords are in use, the greater the opportunity for someone to gain unauthorized knowledge of them. Scheduled changing of passwords hinders the ability of unauthorized system users to crack passwords and gain access to a system.HKSystem Administrator
SV-32289r2_rule 4.012 CCI-000198 MEDIUM The minimum password age must be configured to at least 1 day. 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.HKSystem Administrator
SV-32290r3_rule 4.014 CCI-000200 MEDIUM The password history must be configured to 24 passwords remembered. A system is more vulnerable to unauthorized access when users can recycle the same password several times without being required to change it 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.HKSystem Administrator
SV-32250r4_rule 4.019 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.System Administrator
SV-32291r2_rule 4.020 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.System Administrator
SV-32292r1_rule 4.021 CCI-000366 MEDIUM The built-in guest account will be renamed. A system faces an increased vulnerability threat if the built-in guest account is not renamed or disabled. The built-in guest account is a 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. This account is a member of the group Everyone and has all the rights and permissions associated with that group and could provide access to system resources to unauthorized users.System Administrator
SV-32293r1_rule 4.022 CCI-000366 MEDIUM The built-in administrator account will be renamed. The built-in administrator account is a well-known account. Renaming the account to an unidentified name improves the protection of this account and the system.System Administrator
SV-32253r1_rule 5.003 CCI-000366 MEDIUM Booting into alternate non STIG compliant operating systems will not be permitted. Allowing other operating systems to run on a secure system, can allow users to circumvent security. If more than one operating system is installed on a computer each must be configured to be compliant with STIG guidance.Review each alternate OS boot option for STIG compliance with the SA.System Administrator
SV-32251r2_rule 5.004 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 user ID and password will be captured on the network and give administrator access to an unauthorized user.System Administrator
SV-32252r2_rule 5.005 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.System Administrator
SV-32294r1_rule 5.006 CCI-000056 MEDIUM The system will be configured with a password-protected screen saver. The system should be locked when unattended. Unattended systems are susceptible to unauthorized use. The screen saver should be set at a maximum of 15 minutes and password protected. This protects critical and sensitive data from exposure to unauthorized personnel with physical access to the computer.trueSystem AdministratorInformation Assurance Officer
SV-47875r1_rule 4.027-DC CCI-002235 HIGH Only administrators responsible for the system 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.trueSystem AdministratorInformation Assurance Officer
SV-32255r1_rule 1.016 CCI-000366 LOW Security configuration tools or equivalent processes will be used to configure platforms for security compliance. Security configuration tools, such as Security Templates and Group Policy, allow system administrators to consolidate all security-related system settings into a single configuration file. These settings can then be applied consistently to any number of Windows machines. The Security Configuration tools can use the same configuration file to check platforms for compliance with security policy.System Administrator
SV-32511r1_rule 2.006 CCI-002165 MEDIUM ACLs for system files and directories will conform to minimum requirements. Failure to properly configure ACL file and directory permissions allows the possibility of unauthorized and anonymous modification to the operating system and installed applications.trueSystem Administrator
SV-32257r1_rule 3.027 CCI-000213 LOW Non-administrative user accounts or groups will only have print permissions of Printer Shares. Improperly configured share permissions on printers can permit the addition of unauthorized print devices on the network. Windows shares are a means by which files, folders, printers, and other resources can be published for network users to remotely access. Regular users cannot create shares on their local machines; only Administrators and Power Users have that ability.System Administrator
SV-32295r1_rule 4.006 CCI-001133 LOW Users will be forcibly disconnected when their logon hours expire. Users should 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. This protects critical and sensitive network data from exposure to unauthorized personnel with physical access to the computer.HKSystem Administrator
SV-32259r2_rule 1.006 CCI-000366 HIGH Users with Administrative privilege will be documented and have separate accounts for administrative duties and normal operational tasks. Using a privileged account to perform routine functions makes the computer vulnerable to attack by any virus or Trojan Horse inadvertently introduced during a session that has been granted full privileges. The rule of least privilege should always be enforced.Information Assurance Officer
SV-32296r2_rule 3.034 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.HKSystem Administrator
SV-32297r2_rule 3.040 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.System Administrator
SV-32298r2_rule 3.028 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.System Administrator
SV-32299r1_rule 3.029 CCI-001812 LOW The print driver installation privilege will 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 the Administrators and Print Operators groups.System AdministratorInformation Assurance Officer
SV-32260r3_rule 3.030 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.System AdministratorInformation Assurance Officer
SV-32300r1_rule 3.031 CCI-000366 HIGH The LanMan authentication level will be set to Send NTLMv2 response only\refuse LM & NTLM. The Kerberos v5 authentication protocol is the default for authentication of users who are logging on to domain accounts. The Windows NTLM protocol is retained in later Windows versions for compatibility with clients and servers that are running earlier versions. It is also used to authenticate logons to stand-alone computers that are running later versions. trueSetting this to the required setting may prevent authentication with older operating systems and break some applications.System AdministratorInformation Assurance Officer
SV-32301r1_rule 3.032 CCI-000366 MEDIUM The Ctrl+Alt+Del security attention sequence for logons will 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, you can be assured that any passwords you enter following that sequence are sent only to Windows. If you eliminate the sequence requirement, malicious programs can request and receive your Windows password. Disabling this sequence also suppresses a custom logon banner.HKSystem Administrator
SV-47872r1_rule WINUR-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 from the Network" 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.System Administrator
SV-32303r1_rule 3.047 CCI-000366 MEDIUM The Smart Card removal option will be configured to Force Logoff or Lock Workstation. Determines what should happen when the smart card for a logged-on user is removed from the smart card reader. The options are: - No Action - Lock Workstation - Force LogofftrueHKSystem AdministratorInformation Assurance Officer
SV-32513r1_rule 3.046 CCI-002418 MEDIUM The Windows SMB server will perform SMB packet signing when possible. If this policy is enabled, it causes the Windows Server Message Block (SMB) server to perform SMB packet signing.HKSystem Administrator
SV-32306r1_rule 3.043 CCI-002418 MEDIUM Outgoing secure channel traffic will 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 should be encrypted.If the value for “Domain Member: Digitally encrypt or sign secure channel data (always)” is set to “Enabled”, then this would not be a finding. HKSystem Administrator
SV-32307r1_rule 3.042 CCI-002418 MEDIUM Outgoing secure channel traffic will 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, all outgoing secure channel traffic should be signed.If the value for “Domain Member: Digitally encrypt or sign secure channel data (always)” is set to “Enabled”, then this would not be a finding.HKSystem Administrator
SV-32308r1_rule 3.044 CCI-000366 LOW The computer account password will not be prevented from being reset. Computer account passwords are changed automatically on a regular basis. Enabling this policy to disable automatic password changes can make the system more vulnerable to malicious access. Frequent password changes can be a significant safeguard for your system. If this policy is disabled, a new password for the computer account will be generated every 30 days. HKSystem Administrator
SV-32309r1_rule 3.045 CCI-002418 MEDIUM The Windows SMB client will be enabled to perform SMB packet signing when possible. If this policy is enabled, it causes the Windows Server Message Block (SMB) client to perform SMB packet signing when communicating with an SMB server that is enabled or required to perform SMB packet signing. This policy is defined by default in Local Computer Policy, where it is enabled by default.HKSystem Administrator
SV-32261r1_rule 1.007 CCI-000366 MEDIUM Members of the Backup Operators group will have separate accounts for backup duties and normal operational tasks. 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 the purpose of backup and restore. Members of the Backup Operators group should have special logon accounts for performing their backup duties.trueInformation Assurance Officer
SV-32310r1_rule 3.052 CCI-000366 MEDIUM Ejection of removable NTFS media is not restricted to Administrators. Removable hard drives can be formatted and ejected by others who are not members of the Administrators Group, if they are not properly configured. Formatting and ejecting removable NTFS media should only be done by administrators.HKSystem Administrator
SV-32311r1_rule 3.054 CCI-000366 LOW Users will be warned in advance that their passwords will expire. This setting configures the system to display a warning to users telling them how many days are left before their password expires. By giving the user advanced warning, the user has time to construct a sufficiently strong password.HKSystem Administrator
SV-32312r1_rule 3.055 CCI-000366 LOW The default permissions of Global system objects will be increased. Windows system maintains 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 non-admin users to read shared objects, but not modify shared objects that they did not create.HKSystem Administrator
SV-32313r2_rule 4.028 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 re-established. This protects critical and sensitive network data from exposure to unauthorized personnel with physical access to the computer.HKSystem Administrator
SV-32314r1_rule 3.057 CCI-000196 MEDIUM Reversible password encryption will be disabled. Storing passwords using reversible encryption is essentially the same as storing clear-text versions of the passwords. For this reason, this policy should never be enabled.System Administrator
SV-36168r1_rule AD.3058_2008_R2 CCI-002235 MEDIUM The Server Operators group must have the ability to schedule jobs by means of the AT command disabled. This policy controls the ability of members of the local Server Operators group to schedule AT jobs. If disabled, only administrators can schedule jobs that use AT commands. Unlike Scheduled Tasks which require you to specify the credential under which the task will run, AT jobs run under the authority of whatever account the AT service runs (SYSTEM by default). Non administrators who can schedule AT commands, thus have a means to elevate their privileges. Although this setting is disabled, Server Operators will still be able to schedule jobs using Task Scheduler.HKSystem Administrator
SV-32315r1_rule 3.059 CCI-001764 HIGH Autoplay will be disabled for all drives. Autoplay begins reading from a drive as soon as you insert media in the drive. As a result, the setup file of programs and the music on audio media starts immediately. By default, Autoplay is disabled on removable drives, such as the floppy disk drive (but not the CD-ROM drive), and on network drives. If you enable this policy, you can also disable Autoplay on all drives.HKHKSystem Administrator
SV-36170r2_rule AD.4029_2008_R2 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.System Administrator
SV-36176r2_rule AD.4030_2008_R2 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.System Administrator
SV-36180r2_rule AD.4031_2008_R2 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. System Administrator
SV-36182r2_rule AD.4032_2008_R2 CCI-000366 MEDIUM The Kerberos 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 Ticket Granting Ticket (TGT) may be renewed. This security configuration limits the amount of time an attacker has to crack the TGT and gain access.System Administrator
SV-36186r2_rule AD.4033_2008_R2 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.System Administrator
SV-32262r1_rule 1.024 CCI-000366 MEDIUM System files will be monitored for unauthorized changes. Comparing system files against a baseline on a regular basis will detect the possibility of introduction of malicious code on the system.System AdministratorInformation Assurance Officer
SV-32263r1_rule 3.061 CCI-000068 HIGH Unencrypted remote access will not be permitted to system services. This is a category 1 finding because when unencrypted access to system services is permitted, an intruder can intercept user identification and passwords that are being transmitted in clear text. This could give an intruder unlimited access to the network.Information Assurance Officer
SV-32264r1_rule 2.015 CCI-001090 MEDIUM File share ACLs will be reconfigured to remove the Everyone group. By default, the Everyone group is given full control to new file shares. When a share is created, permissions should be reconfigured to give the minimum access to those accounts that require it.System created shares should be excluded from the check.trueSystem Administrator
SV-32265r1_rule 1.025 CCI-000366 MEDIUM Servers will 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 Category III, if there is an active JIDS or Firewall protecting the network. System AdministratorInformation Assurance Officer
SV-32316r2_rule 3.062 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.System AdministratorInformation Assurance Officer
SV-46295r1_rule 3.063-DC CCI-001090 HIGH Named pipes that can be accessed anonymously must be configured with limited values on domain controllers. This is a Category 1 finding due to 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 may be accessed anonymously.System Administrator
SV-32484r2_rule 3.064 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.System Administrator
SV-32317r1_rule 3.065 CCI-001090 HIGH Network shares that can be accessed anonymously will not be allowed. This is a Category 1 finding because the potential for gaining unauthorized system access. Any shares listed can be accessed by any network user. This could lead to the exposure or corruption of sensitive data. Enabling this setting is very dangerous.HKSystem Administrator
SV-32318r1_rule 3.068 CCI-001090 HIGH Solicited Remote Assistance will not be allowed. This setting controls whether or not solicited remote assistance is allowed from this computer. Solicited assistance is help that is specifically requested by the user. This is a Category 1 finding because it may allow unauthorized parties access to the resources on the computer.HKSystem Administrator
SV-32319r1_rule 4.036 CCI-000366 HIGH The use of local accounts with blank passwords will be restricted to console logons only. This is a Category 1 finding because no accounts with blank passwords should exist on a system. The password policy should prevent this from occurring. However, if a local account with a blank password does exist, enabling this setting will limit the account to local console logon only.HKSystem Administrator
SV-32320r1_rule 3.069 CCI-000366 MEDIUM A system must be logged on to before removing from a docking station. This setting controls the ability to undock the system without having to log on. Since the removal of a computer should be controlled, users should have to log on before undocking the computer to ensure that they have the appropriate rights to undock the system. In addition to software security settings, physical security should be in place to prevent unauthorized removal of computers.HKSystem Administrator
SV-32321r1_rule 4.043 CCI-000366 LOW The maximum age for machine account passwords will be set to requirements. This setting controls the maximum password age that a machine account may have. This setting should be set to no more than 30 days, ensuring the machine changes its password monthly.HKSystem Administrator
SV-32322r1_rule 4.044 CCI-002418 MEDIUM The system will be configured to require a strong session key. This setting controls the required strength of a session key. Setting this value in a domain containing Windows NT or older operating systems will prevent those systems from authenticating. This setting can also prevent a system from being joined to a domain.HKSystem AdministratorInformation Assurance Officer

SV-36295r2_rule AD.3106_2008_R2 CCI-002418 MEDIUM Domain Controllers must require LDAP 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 can 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.trueHKSystem AdministratorECSC-1
SV-36192r1_rule AD.3107_2008_R2 CCI-000366 LOW The domain controller 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. HKSystem Administrator
SV-32359r2_rule 5.098 CCI-002385 LOW The system must limit how many times unacknowledged TCP data is retransmitted.

SV-32361r2_rule 3.109 CCI-000186 MEDIUM Users must be required to enter a password to access private keys stored on the computer. Configuring this setting so that users must provide a password (distinct from their domain password) every time they use a key makes it more difficult for an attacker to access locally stored user keys, even if the attacker takes control of the user's computers and determines their logon password. HKSystem Administrator
SV-32362r1_rule 3.110 CCI-000381 LOW Optional Subsystems will 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; anything the second user does with that process will be performed with the privileges of the first user. trueHKSystem Administrator
SV-32499r1_rule 5.103 CCI-001453 MEDIUM The Remote Desktop Session Host will require secure RPC communications. Allowing unsecure RPC communication exposes the server 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. HKSystem Administrator
SV-32364r1_rule 3.112 CCI-000366 MEDIUM Group Policy objects will be reprocessed even if they have not changed.

SV-32368r1_rule 3.116 CCI-001090 HIGH Anonymous access to Named Pipes and Shares will be restricted. This is a Category 1 finding because of 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. When this setting is disabled, Network shares can be accessed by any network user. This could lead to the exposure or corruption of sensitive data.HKSystem Administrator
SV-32369r1_rule 4.013 CCI-000205 MEDIUM For systems utilizing a logon ID as the individual identifier, passwords will, 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 causing the device, information, or the local network to be compromised or a denial of service.

SV-38994r3_rule DS00.0120_2008_R2 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.System Administrator
SV-38996r2_rule DS00.1190_2008_R2 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.System Administrator
SV-38999r2_rule DS00.0150_2008_R2 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.System Administrator
SV-39001r2_rule DS00.0151_2008_R2 CCI-000366 LOW The time synchronization tool must be configured to enable logging of time source switching.

SV-39002r2_rule DS00.1180_2008_R2 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.System Administrator
SV-39004r2_rule DS00.3260_2008_R2 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.

SV-39005r2_rule DS00.0210_2008_R2 CCI-002235 HIGH The Synchronize directory service data user right must be configured to include no accounts or groups (blank). A Windows account with the "Synchronize directory service data" right has the ability to read all information in the AD database. This bypasses the object access permissions that would otherwise restrict access to the data. The scope of access granted by this right is too broad for secure usage. Specific object permissions or other group membership assignments could be used to provide access on an appropriate scale.System Administrator
SV-32274r2_rule 3.122 CCI-000366 MEDIUM The Windows 2008 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.

SV-39012r2_rule DS00.3130_2008_R2 CCI-000366 HIGH Directory data (outside the root DSE) of a non-public directory must be configured to prevent anonymous access. To the extent that anonymous access to directory data (outside the root DSE) is permitted, read access control of the data is effectively disabled. If other means of controlling access (such as, network restrictions) are compromised, there may be nothing else to protect the confidentiality of sensitive directory data. The following network controls allow the finding severity to be downgraded to a CAT II 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. Premise firewall or host restrictions prevent access to ports 389, 636, 3268, and 3269 from client hosts not explicitly identified by domain (.mil) or IP address.System Administrator
SV-39014r2_rule DS00.2140_2008_R2 CCI-000185 HIGH Domain Controller PKI certificates must be issued by the DoD PKI or an approved External Certificate Authority (ECA). 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, then this is a CAT II finding.

SV-39015r2_rule DS00.3370_2008_R2 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. System Administrator

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).System Administrator

SV-47866r2_rule 1.006-01 CCI-000366 HIGH Administrative accounts must not be used with applications that access the Internet, such as web browsers, or with potential Internet sources, such as email. Using applications that access the internet or have potential internet sources using administrative privileges exposes a system to compromise. 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 user account. Since administrative user accounts may generally change or work around technical restrictions for running a web browser or other applications, it is essential that policy requires administrative users 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.

The impact of missing audit data is related to the type of object. A failure to capture audit data for objects used by identification, authentication, or authorization functions could degrade or eliminate the ability to track changes to access policy for systems or data. For Active Directory (AD), there are a number of critical object types in the domain naming context of the AD database for which auditing is essential. This includes Group Policy objects. Because changes to these objects can significantly impact access controls or the availability of systems, the absence of auditing data makes it impossible to identify the source of changes that impact the confidentiality, integrity, and availability of data and systems throughout an AD domain. The lack of proper auditing can result in insufficient forensic evidence needed to investigate an incident and prosecute the intruder.

Because changes to these objects can significantly impact access controls or the availability of systems, the absence of auditing data makes it impossible to identify the source of changes that impact the confidentiality, integrity, and availability of data and systems throughout an AD domain. The lack of proper auditing can result in insufficient forensic evidence needed to investigate an incident and prosecute the intruder.

SV-56719r2_rule WINAD-000004-DC_2008_R2 CCI-002235 HIGH The Active Directory Domain Controllers Organizational Unit (OU) object must have the proper access control permissions. When Active Directory (AD) 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 that rely on the directory service. The Domain Controllers OU object requires special attention as the Domain Controllers are central to the configuration and management of the domain. Inappropriate access permissions defined for the Domain Controllers OU could allow an intruder or unauthorized personnel to make changes which could lead to the compromise of the domain.
SV-56720r1_rule WINAD-000005-DC_2008_R2 CCI-002235 HIGH Domain created Active Directory Organizational Unit (OU) objects must have proper access control permissions. When Active Directory (AD) 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 that rely on the directory service. AD Organizational Unit (OU) objects require special attention. In a distributed administration model (i.e., help desk), OU objects are more likely to have access permissions changed from the secure defaults. Inappropriate access permissions defined for OU objects could allow an intruder or unauthorized personnel to add or delete accounts in the OU. This could result in unauthorized access to data or a Denial of Service to authorized users.If any OU with improper permissions includes identification or authentication data (e.g., accounts, passwords, or password hash data) used by systems to determine access control, the severity is Category I (e.g., OUs that include user accounts, including service/application accounts). If the OU with improper permissions does not include identification and authentication data used by systems to determine access control, the severity is Category II (e.g., Workstation, Printer OUs).

SV-101877r1_rule WINAD-000015-DC_2008_R2 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.
