Vuln Rule Version CCI Severity Title Description
SV-29342r1_rule 2.005 HIGH Systems must be at supported service packs (SP) or releases 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 AdministratorVIVM-1
SV-18421r1_rule 3.007 LOW The system allows shutdown from the logon dialog box. Preventing display of the shutdown button in the logon dialog box may encourage a hard shut down with the power button. (However, displaying the shutdown button may allow individuals to shut down a system anonymously.)HKSystem AdministratorECSC-1
SV-29471r1_rule 2.007 MEDIUM File-auditing configuration does not meet minimum requirements. Improper modification of the core system files can render a system inoperable. Further, modifications to these system files can have a significant impact on the security configuration of the system. Auditing of significant modifications made to the system files provides a method of determining the responsible party.Automated checking sometimes reports this as a false finding. If a manual review of a questionable finding shows auditing to be set correctly, then this would not be a finding.System AdministratorECAR-3, ECAR-1, ECAR-2
SV-29763r1_rule 3.002 MEDIUM POSIX subsystem registry key exists. For the system to comply with Security requirements, the POSIX subsystem must be disabled.HKSystem AdministratorECSC-1
SV-1084r1_rule 3.003 LOW System pagefile is cleared upon shutdown. This check verifies that Windows is not configured to wipe clean the system page file during a controlled system shutdown.System AdministratorECRC-1
SV-1085r1_rule 3.006 LOW Floppy media devices are not allocated upon user logon. This check verifies that Windows is configured to not limit access to floppy drives when a user is logged on locally per the FDCC.System AdministratorECLP-1, ECSC-1
SV-1089r3_rule 3.011 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 OfficerECWM-1
SV-1090r2_rule 3.013 LOW Caching of logon credentials is not 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 is disconnected from the network or domain controllers are not available. Even though the credential cache is well-protected, storing encrypted copies of users passwords on systems do not always have the same physical protection required for domain controllers. If a system is attacked, the unauthorized individual may isolate the password to a domain user account using a password-cracking program, and gain access to the domain.HKSystem AdministratorECSC-1
SV-18444r1_rule 3.015 LOW System halts once an event log has reached its maximum size. This check verifies that the system will not halt if the audit logs become full.System AdministratorECRR-1
SV-1093r1_rule 3.018 HIGH Anonymous shares are not 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. System AdministratorInformation Assurance OfficerECSC-1, PRNK-1
SV-28984r1_rule 4.002 MEDIUM Number of allowed bad-logon attempts does not 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 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 AdministratorECLO-1, ECLO-2
SV-29636r1_rule 4.003 MEDIUM Time before bad-logon counter is reset does not meet minimum requirements. This parameter specifies the amount of time that must pass between two successive login attempts to ensure that a lockout will occur. The smaller this value is, the less effective the account lockout feature will be in protecting the local system.HKSystem AdministratorECLO-1, ECLO-2
SV-29640r1_rule 4.004 MEDIUM Lockout duration does not meet minimum requirements. This parameter specifies the amount of time that must pass before a locked-out account is automatically unlocked by the system.HKSystem AdministratorECLO-1, ECLO-2
SV-28988r1_rule 4.009 HIGH Unauthorized users are granted right to Act as part of the operating system. This is a Category 1 finding because users and user groups that are assigned this right can bypass all security protective mechanisms that apply to all users, including administrators. Accounts with this right should have passwords with the maximum length and be kept in a locked container accessible only by the IAO and his designated backup. Some applications require this right to function. Any exception needs to be documented with the IAO.trueRemoving application accounts from this right may cause the applications to stop functioning.System AdministratorInformation Assurance OfficerECLP-1
SV-18391r2_rule 4.010 MEDIUM User rights and advanced user rights settings do not meet minimum requirements. Inappropriate granting of user and advanced user rights can provide system, administrative, and other high level capabilities not required by the normal user.trueArbitrarily removing application accounts from certain User Rights may cause the applications to cease functioning.System AdministratorInformation Assurance OfficerECLP-1
SV-29644r1_rule 4.011 MEDIUM Maximum password age does not meet minimum requirements. The longer a password is in use, the greater the opportunity for someone to gain unauthorized knowledge of the passwords. Further, scheduled changing of passwords hinders the ability of unauthorized system users to crack passwords and gain access to a system.HKSystem AdministratorIAIA-2, IAIA-1
SV-28992r1_rule 4.012 MEDIUM Minimum password age does not meet minimum 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.HKSystem AdministratorIAIA-2, IAIA-1
SV-29648r1_rule 4.014 MEDIUM Password uniqueness does not 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 a password to a unique password on a regularly scheduled basis. This enables users to effectively negate the purpose of mandating periodic password changes.HKSystem AdministratorIAIA-1, IAIA-2
SV-1113r1_rule 4.020 MEDIUM The built-in guest account is not 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. This account is a member of the Everyone user group and has all the rights and permissions associated with that group, which could subsequently provide access to system resources to anonymous users.System AdministratorIAAC-1
SV-1114r1_rule 4.021 MEDIUM The built-in guest account has not been 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 AdministratorIAAC-1
SV-1115r1_rule 4.022 MEDIUM The built-in administrator account has not been 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 AdministratorIAAC-1
SV-29486r1_rule 5.002 MEDIUM Event log sizes do not meet minimum requirements. Inadequate log size will cause the log to fill up quickly and require frequent clearing by administrative personnel.trueMicrosoft recommends that the combined size of all the event logs (including DNS logs, Directory Services logs, and Replication logs on Servers or Domain Controllers) should not exceed 300 megabytes. Exceeding the recommended value can impact performance.System AdministratorInformation Assurance OfficerECRR-1
SV-18445r1_rule 2.006 MEDIUM ACLs for system files and directories do not 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.If a manual check of a questionable ACL setting shows that it has been set to meet or is more restrictive than minimum requirements, then it will not be counted as a finding.trueSystem AdministratorECCD-1, ECCD-2
SV-1136r1_rule 4.006 LOW Users are not forcibly disconnected when 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 AdministratorECSC-1
SV-1139r1_rule 3.024 MEDIUM The option to prevent the password in dial-up networking from being saved is not enabled. The default Windows configuration enables the option to save the password used to gain access to a remote server using the dial-up networking feature. With this option enabled, an unauthorized user who gains access to a Windows machine would also have access to remote servers with which the machine uses dial-up networking to communicate. Disabling this option will introduce another layer of security and help limit the scope of any security compromise to the local machine.HKSystem AdministratorECSC-1
SV-1141r1_rule 3.034 MEDIUM Unencrypted password is sent to 3rd 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.HKSystem AdministratorECCT-1, ECCT-2
SV-1145r1_rule 3.040 HIGH Administrator automatic logon is enabled. This is a category 1 finding because it will directly log on to the system with administrator privileges when the machine is rebooted. This would give full access to any unauthorized individual who reboots the computer. By default this setting is not enabled. If this setting exists, it should be disabled. If this capability exists, the password may also be present in the registry, and must be removed.HKSystem AdministratorECSC-1
SV-29511r1_rule 4.024 LOW Local users exist on a workstation in a domain. To minimize potential points of attack, local users, other than built-in accounts such as Administrator and Guest accounts, should not exist on a workstation in a domain. Users should always log onto workstations in a domain domain with their domain accounts. This does not apply to laptop PCs which are designed to function both on the domain and off the domain.This does not apply to laptops that are designed to function both as part of a domain and separate from it.trueSystem AdministratorInformation Assurance OfficerIAAC-1
SV-29682r1_rule 3.028 LOW The built-in Microsoft password filter is not enabled. The use of complex passwords increases their strength against guessing. This policy setting configures the system to verify that newly-created passwords conform to the Windows password complexity policy.System AdministratorIAIA-1, IAIA-2
SV-1151r1_rule 3.029 LOW Print driver installation privilege is not restricted to administrators. By default, the print spooler allows any user to add and to delete printer drivers on the local system. This capability should be restricted to authorized personnel.trueSystem AdministratorInformation Assurance OfficerECLP-1
SV-1153r1_rule 3.031 HIGH The Send download LanMan compatible password option is not set to Send NTLMv2 response only\refuse LM. The Kerberos v5 authentication protocol is the default for authentication of users who are logging on to domain accounts. NTLM is retained in later Windows versions for compatibility with clients and servers that are running earlier versions of Windows. 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 OfficerIAIA-1, IAIA-2
SV-1154r1_rule 3.032 MEDIUM Ctrl+Alt+Del security attention sequence is Disabled. 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 AdministratorECSC-1
SV-1157r1_rule 3.047 MEDIUM The Smart Card removal option is set to take no action. 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 AdministratorECSC-1
SV-29017r1_rule 3.048 LOW The Recovery Console SET command is enabled. Enabling this option enables the Recovery Console SET command, which allows you to set Recovery Console environment variables. This permits floppy copy and access to all drives and folders.HKSystem AdministratorECCD-2, ECCD-1
SV-29021r1_rule 3.049 HIGH The Recovery Console option is set to permit automatic logon to the system. This is a Category 1 finding because if this option is set, the Recovery Console does not require you to provide a password and will automatically log on to the system, giving Administrator access to system files. By default, the Recovery Console requires you to provide the password for the Administrator account before accessing the system.HKSystem AdministratorECCD-2, ECCD-1
SV-1160r1_rule 3.050 LOW The unsigned driver installation behavior is improperly set. Determines what should happen when an attempt is made to install a device driver (by means of the Windows device installer) that has not been certified by the Windows Hardware Quality Lab (WHQL). The options are: - Silently succeed - Warn but allow installation - Do not allow installationtrueSystem AdministratorInformation Assurance OfficerDCSL-1
SV-1162r1_rule 3.046 MEDIUM The Windows SMB server is not enabled to 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 AdministratorECSC-1
SV-1163r1_rule 3.043 MEDIUM Outgoing secure channel traffic is not 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 AdministratorECCT-1, ECCT-2
SV-1164r1_rule 3.042 MEDIUM Outgoing secure channel traffic is not 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 AdministratorDCNR-1
SV-1165r1_rule 3.044 LOW The computer account password is prevented from being reset. As a part of Windows security, computer account passwords are changed automatically. 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 week.HKSystem AdministratorIAIA-1, IAIA-2
SV-1166r1_rule 3.045 MEDIUM The Windows SMB client is not 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.HKSystem AdministratorECSC-1
SV-1171r1_rule 3.052 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 AdministratorECLP-1
SV-1172r1_rule 3.054 LOW Users are not 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 AdministratorECSC-1
SV-1173r1_rule 3.055 LOW The default permissions of Global system objects are not 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 AdministratorECSC-1
SV-1174r1_rule 4.028 LOW Amount of idle time required before suspending a session is improperly set. Administrators should use this setting 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.HKSystem AdministratorECSC-1
SV-29687r1_rule 3.057 MEDIUM Reversible password encryption is not 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 AdministratorIAIA-1, IAIA-2
SV-2374r2_rule 3.059 HIGH The system is configured to autoplay removable media. 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 AdministratorECSC-1
SV-6274r1_rule 3.063 HIGH Unauthorized named pipes are accessible with anonymous credentials. This is a Category 1 finding because 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.System AdministratorECSC-1
SV-6275r1_rule 3.064 HIGH Unauthorized registry paths are remotely accessible. This is a Category 1 finding because it could give unauthorized individuals access to the Registry. It controls which registry paths are accessible from a remote computer.System AdministratorECCD-2, ECCD-1
SV-6276r1_rule 3.065 HIGH Unauthorized shares can be accessed anonymously. 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.System AdministratorECCD-2, ECCD-1
SV-3341r1_rule 3.066 HIGH Remote control of a Terminal Service session is allowed. This setting is used to control the rules for remote control of Terminal Services user sessions. This is a Category 1 finding because remote control of sessions could permit an unauthorized user to access sensitive information on the controlled system.HKSystem AdministratorECSC-1
SV-3343r1_rule 3.068 HIGH Solicited Remote Assistance is 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 AdministratorECSC-1
SV-3344r1_rule 4.036 HIGH The use of local accounts with blank passwords is not 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 AdministratorIAIA-1
SV-3348r1_rule 5.017 MEDIUM The user is allowed to launch Windows Messenger (MSN Messenger, .NET Messenger). This setting prevents the Windows Messenger client from being run. Instant Messaging clients must be in compliance of with the Instant Messaging STIG. Windows Messenger should not be active on Windows unless the instant messaging system is a Managed Enterprise Service for unclassified data for which the DAA has approved.trueSystem AdministratorInformation Assurance OfficerECIM-1
SV-3349r1_rule 5.018 MEDIUM Windows Messenger (MSN Messenger, .NET messenger) is run at system startup. This setting prevents the automatic launch of Windows Messenger at user logon. Instant Messaging clients must be in compliance of with the Instant Messaging STIG. Windows Messenger should not be active on Windows unless the instant messaging system is a Managed Enterprise Service for unclassified data for which the DAA has approved.trueSystem AdministratorInformation Assurance OfficerECIM-1
SV-3369r1_rule 4.048 MEDIUM Restricted accounts are not disabled. Several new accounts are created as part of the default installation. As these accounts are well known they may represent prime attack targets. To help prevent attacks using the well-known accounts the following accounts should be disabled: HelpAssistant and Support_388945a0.HKSystem AdministratorIAAC-1
SV-3373r1_rule 4.043 LOW The maximum age for machine account passwords is not 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 AdministratorIAIA-2, IAIA-1
SV-3374r1_rule 4.044 MEDIUM The system is not 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 OfficerECSC-1
SV-18419r1_rule 4.045 LOW Domain Controller authentication is not required to unlock the workstation. This setting controls the behavior of the system when you attempt to unlock the workstation. If this setting is enabled, the system will pass the credentials to the domain controller (if in a domain) for authentication before allowing the system to be unlocked. This will be set to disabled per the FDCC.HKSystem AdministratorECSC-1
SV-3376r1_rule 3.070 MEDIUM The system is configured to permit storage of credentials or .NET Passports. This setting controls the storage of authentication credentials or .NET passports on the local system. Such credentials should never be stored on the local machine as that may lead to account compromise.HKSystem AdministratorECSC-1
SV-3377r1_rule 3.071 MEDIUM The system is configured to give anonymous users Everyone rights. This setting helps define the permissions that anonymous users have. If this setting is enabled then anonymous users have the same rights and permissions as the built-in Everyone group. Anonymous users should not have these permissions or rights.HKSystem AdministratorInformation Assurance OfficerECSC-1, ECLP-1, ECCD-2, ECCD-1
SV-3378r1_rule 3.072 MEDIUM The system is not 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.HKSystem AdministratorECLO-1
SV-3379r1_rule 3.073 HIGH The system is configured to store the LAN Manager hash of the password in the SAM. 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. The LAN Manager hash is a weak encryption algorithm and there are several tools available that use this hash to retrieve account passwords.HKSystem AdministratorInformation Assurance OfficerIAIA-2, ECSC-1, IAIA-1
SV-3380r1_rule 3.074 MEDIUM The system is not configured to force users to log off when their allowed logon hours expire. 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, then this should be enforced.HKSystem AdministratorECSC-1
SV-3381r1_rule 3.075 MEDIUM The system is not configured to recommended LDAP client signing requirements. This setting controls the signing requirements for LDAP clients. This setting should be set to Negotiate signing or Require signing depending on the environment and type of LDAP server in use.HKSystem AdministratorECSC-1
SV-3382r1_rule 3.076 MEDIUM The system is not configured to meet the minimum requirement for session security for NTLM SSP based Clients. Microsoft has implemented a variety of security support providers for use with RPC sessions. In a homogenous Windows environment, all of the options should be enabled and testing should be performed in a heterogeneous environment to determine the maximum-security level that provides reliable functionality.trueMicrosoft warns that setting these may prevent the client from communicating with legacy servers that do not support them. “Require NTLMv2 session security” will prevent authentication, if the “Network security: LAN Manager authentication level” is set to permit NTLM or LM authentication. System AdministratorInformation Assurance OfficerECCT-1, ECCT-2
SV-3383r1_rule 3.077 MEDIUM The system is not 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 should 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.HKSystem AdministratorECCT-2, ECCT-1
SV-3384r1_rule 2.016 MEDIUM The system is not configured to make the object creator the owner of objects created by administrators. Either the object creator or the Administrators group owns objects created by members of the Administrators group. In order to ensure accurate auditing and proper accountability, the default owner should be the object creator.HKSystem AdministratorECSC-1
SV-3385r1_rule 3.078 MEDIUM The system is configured to allow case insensitivity. 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 should be restricted. To prevent this from happening, case insensitivity restrictions should be required.HKSystem AdministratorECSC-1
SV-29274r1_rule 5.027 MEDIUM The system is configured to allow remote desktop sharing through NetMeeting. Remote desktop sharing enables several users to interact and control one desktop. This could allow unauthorized users to control the system. Remote desktop sharing should be disabled.HKSystem AdministratorECSC-1
SV-3453r1_rule 5.042 MEDIUM Terminal Services is not configured to always prompt a client for passwords upon connection. This setting, which is located under the Encryption and Security section of the Terminal Services configuration option, 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.HKSystem AdministratorIAIA-1, IAIA-2
SV-3454r2_rule 5.043 MEDIUM Terminal Services is not 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 Terminal Services sessions in both directions.HKSystem AdministratorECCT-1, ECCT-2
SV-3455r1_rule 5.044 MEDIUM Terminal Services is configured to use a common temporary folder for all sessions. This setting, which is located under the Temporary Folders section of the Terminal Services configuration option, controls the use of per session temporary folders or of a communal temporary folder. If this setting is enabled, only one temporary folder is used for all terminal services sessions. If a communal temporary folder is used, it might be possible for users to access other users temporary folders.HKSystem AdministratorECRC-1
SV-3456r1_rule 5.045 MEDIUM Terminal Services is not configured to delete temporary folders. This setting, which is located under the Temporary Folders section of the Terminal Services configuration option, controls the deletion of the temporary folders when the session is terminated. Temporary folders should always be deleted after a session is over to prevent hard disk clutter and potential leakage of information.HKSystem AdministratorECRC-1
SV-3457r1_rule 5.046 MEDIUM Terminal Services is not 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 should be terminated as soon as possible.HKSystem AdministratorECSC-1
SV-3458r1_rule 5.047 MEDIUM Terminal Services idle session time limit does not meet the requirement. This setting controls how long a session may be idle before it is automatically disconnected from the server. Users should disconnect if they plan on being away from their terminals for extended periods of time. Idle sessions should be disconnected after 15 minutes.HKSystem AdministratorECSC-1
SV-3459r1_rule 5.048 MEDIUM Terminal Services is not configured to allow only the original client to reconnect. This setting, which is located under the Sessions section of the Terminal Services configuration option, controls whether a different client may be used to resume a disconnected session. Only the original client should be able to resume a session to help prevent session hijacking.HKSystem AdministratorECSC-1
SV-3460r1_rule 5.049 MEDIUM Terminal Services is not configured to disconnect clients when time limits are exceeded. This setting, which is located under the Sessions section of the Terminal Services configuration option, controls whether or not clients are forcefully disconnected if their terminal services time limit is exceeded. If time limits are established for users, they should be enforced.HKSystem AdministratorECSC-1
SV-3469r2_rule 3.080 MEDIUM The system is configured to prevent background refresh of Group Policy. 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.HKSystem AdministratorECSC-1
SV-3470r1_rule 3.082 MEDIUM The system is configured to allow unsolicited remote assistance offers. This setting controls whether unsolicited offers of help to this computer are allowed. The list of users allowed to offer remote assistance to this system is accessed by pressing the Helpers button.trueRemote Assist - Offer v2HKThis is a documentable finding on workstations with the following mitigations. -Users must be trained to include the following: -Who they can accept assistance offer from. Offer must be in response to help desk request or confirmed with help desk if unsolicited offer comes through. -Users must know how to accept request, allow view or control, and how to disconnect a remote assistance session. -Users needs monitor the assistance activity at the workstation while it is occurring. -The support personnel allowed to offer assistance (helpers) must be limited and documented. -Port 3389 should be blocked at the perimeter to prevent other access.

SV-3471r1_rule 3.083 MEDIUM The system is configured to automatically forward 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 should be disabled to prevent the release of such information.trueHKSystem AdministratorInformation Assurance OfficerECSC-1
SV-3478r1_rule 3.087 MEDIUM The system is configured to allow installation of printers using kernel-mode drivers. Kernel-mode drivers are drivers that operate in kernel mode. Kernel mode allows virtually unlimited access to hardware and memory. A poorly written kernel driver may cause system instability and data corruption. Malicious code inserted in a kernel-mode driver has almost no limit on what it may do. Most modern printers do not require kernel-mode drivers.This setting will prevent some applications from installing PDF print drivers. If necessary temporarily disable this setting while installing a legitimate kernel-mode driver.HKSystem AdministratorDCSL-1
SV-3479r1_rule 3.088 MEDIUM The system is not 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 systems path environment variable. An unauthorized DLL inserted into an applications working directory could allow malicious code to be run on the system. Creating the following registry key and setting the appropriate value forces the system to search the %Systemroot% for the DLL before searching the current directory or the rest of the path.HKSystem AdministratorECSC-1
SV-3480r2_rule 5.060 MEDIUM 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.HKSystem AdministratorDCSL-1
SV-3666r1_rule 3.089 MEDIUM The system is not configured to meet the minimum requirement for session security for NTLM SSP based Servers. Microsoft has implemented a variety of security support providers for use with RPC sessions. In a homogenous Windows environment, all of the options should be enabled and testing should be performed in a heterogeneous environment to determine the maximum-security level that provides reliable functionality.trueMicrosoft warns that setting these may prevent the server from communicating with legacy clients that do not support them. “Require NTLMv2 session security” will prevent authentication, if the “Network security: LAN Manager authentication level” is set to permit NTLM or LM authentication.

SV-49933r2_rule WIN00-000001 HIGH Windows operating systems that are no longer supported by the vendor for security updates must not be installed on a system. Windows operating systems that are no longer supported by Microsoft for security updates are not evaluated or updated for vulnerabilities leaving them open to potential attack. Organizations must transition to a supported operating system to ensure continued support.DCSQ-1
SV-4108r1_rule 3.092 LOW The system does not generate an audit event when the audit log reaches a percent full threshold. When the audit log reaches a given percent full, an audit event is written to the security log. The event ID is 523 and is recorded as a success audit under the category of System. This option may be especially useful if the audit logs are set to be cleared manually. A recommended setting would be 90 percent.trueSystem AdministratorInformation Assurance OfficerECRR-1
SV-4109r1_rule 3.093 LOW The system is configured to allow dead gateway detection. Allows TCP to peform dead-gateway detection, switching to a backup gateway if a number of connections to a gateway are experiencing difficulty.

SV-4116r1_rule 3.101 LOW The system is configured to allow name-release attacks. Prevents a denial-of-service (DoS) attack against a WINS server. The DoS consists of sending a NetBIOS Name Release Request to the server for each entry in the servers cache, causing a response delay in the normal operation of the servers WINS resolution capability.HKSystem AdministratorECSC-1
SV-4117r1_rule 3.102 LOW The system is configured to allow SYN attacks. Adjusts retransmission of TCP SYN-ACKs. When enabled, connection responses time out more quickly in the event of a SYN DoS attack.HKSystem AdministratorECSC-1
SV-4437r1_rule 5.097 LOW TCP connection response retransmissions are not controlled. 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 no longer is able to respond to legitimate requests. Microsoft cautions that setting this to “No retransmission, half-open connections dropped after 3 seconds” may cause legitimate connection attempts from distant clients to fail due to time-out. HKSystem AdministratorECSC-1
SV-4438r1_rule 5.098 LOW TCP data retransmissions are not controlled. 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 no longer is able to respond to legitimate requests. HKSystem AdministratorECSC-1
SV-4442r1_rule 5.102 LOW This check verifies that Windows is 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 onto the system before the lock takes effect.An issue was identified where the Security Options files and analysis templates included the registry value for this setting as a Dword type however it should have been a String value. This has been reported to Microsoft and the Security Options files and analysis templates included with the checklists have been corrected as of the December 2008 release.HKSystem AdministratorPESL-1
SV-4447r1_rule 5.103 MEDIUM The Terminal Server does not require secure RPC communication. 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 AdministratorECSC-1
SV-4448r1_rule 3.112 MEDIUM Group Policy objects are not reprocessed 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. HKSystem AdministratorECSC-1
SV-7072r1_rule 3.113 MEDIUM Outgoing secure channel traffic is not encrypted or signed.

SV-7074r1_rule 3.114 MEDIUM The Windows Server SMB client is not enabled to always perform SMB packet signing. 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.If the environment is a mixed one, with down-level OSs, or maintains trusts with down-level OSs, then this to the required setting could cause compatibility problems. HKSystem AdministratorECSC-1
SV-7076r1_rule 3.115 MEDIUM The Windows Server SMB server is not enabled to always perform SMB packet signing. If this policy is enabled, it causes the Windows Server Message Block (SMB) server to always perform SMB packet signing.If the environment is a mixed one, with down-level OSs, or maintains trusts with down-level OSs, then configuring this to the required setting could cause compatibility problems. HKSystem AdministratorECSC-1
SV-29386r1_rule 4.013 MEDIUM For systems utilizing a logon ID as the individual identifier, passwords are not at a minimum of 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. Strong passwords may invite users to write down the passwords. Ensure that all users store passwords in a secured location.HKSystem AdministratorInformation Assurance OfficerIAIA-1, IAIA-2
SV-29741r1_rule 4.008 MEDIUM Auditing records are configured as required. Maintaining an audit trail of system activity logs can help identify configuration errors, troubleshoot service disruptions, analyze compromises that have occurred as well as detect an attack that has begun or is about to begin. Audit logs are necessary to provide a trail of evidence in case the system or network is compromised. Without an audit trail that provides information as to event that occurred and if it was successful or unsuccessful, it is difficult to analyze a series of events to determine the steps used by an attacker to compromise a system or network, or what exactly happened that led to a denial of service. Collecting data such as the successful and unsuccessful events is essential for analyzing the security of information assets and detecting signs of suspicious and unexpected behavior.noneHKHKSystem AdministratorInformation Assurance OfficerECAR-3, ECAR-2
