Caching of logon credentials must be limited.

RMF Control: CM-6
Severity: Low
CCI: CCI-000366
Version: 3.013
Vuln IDs: V-1090
Rule IDs: SV-25047r3_rule

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

Fix: F-63547r1_fix

If the system is not a member of a domain, this is NA. Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> "Interactive Logon: Number of previous logons to cache (in case Domain Controller is not available)" to "2" logons or less.

RMF Control: AC-7
Severity: Medium
CCI: CCI-000044
Version: 4.002
Vuln IDs: V-1097
Rule IDs: SV-25015r2_rule

The account lockout feature, when enabled, prevents brute-force password attacks on the system. The higher this value is, the less effective the account lockout feature will be in protecting the local system. The number of bad logon attempts must be reasonably small to minimize the possibility of a successful password attack, while allowing for honest errors made during a normal user logon.HKSystem Administrator

Fix: F-65495r3_fix

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Account Policies >> Account Lockout Policy >> "Account lockout threshold" to "3" or less invalid logon attempts (excluding "0", which is unacceptable).

Severity: Medium
CCI: CCI-000200
Version: 4.014
Vuln IDs: V-1107
Rule IDs: SV-25008r3_rule

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

Fix: F-65507r2_fix

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Account Policies >> Password Policy >> "Enforce password history" to "24" passwords remembered.

RMF Control: CM-6
Severity: Medium
CCI: CCI-000366
Version: 4.021
Vuln IDs: V-1114
Rule IDs: SV-25024r2_rule

The built-in guest account is a well-known user account on all Windows systems and, as initially installed, does not require a password. This can allow access to system resources by unauthorized users. Renaming this account to an unidentified name improves the protection of this account and the system.System Administrator

Users are not forcibly disconnected when logon hours expire.

RMF Control: SC-10
Severity: Low
CCI: CCI-001133
Version: 4.006
Vuln IDs: V-1136
Rule IDs: SV-25063r1_rule

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. Forcibly disconnecting users when logon hours expire protects critical and sensitive network data from exposure to unauthorized personnel with physical access to the computer.HKSystem Administrator

Fix: F-6572r1_fix

Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> “Microsoft Network Server: Disconnect Clients When Logon Hours Expire” to “Enabled”.

RMF Control: IA-5
Severity: Medium
CCI: CCI-000197
Version: 3.034
Vuln IDs: V-1141
Rule IDs: SV-25056r2_rule

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

Fix: F-66901r1_fix

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> Security Options >> "Microsoft Network Client: Send unencrypted password to third-party SMB servers" to "Disabled".

Severity: Medium
CCI: CCI-000366
Version: 3.040
Vuln IDs: V-1145
Rule IDs: SV-25064r2_rule

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

Fix: F-43226r1_fix

Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> "MSS: (AutoAdminLogon) Enable Automatic Logon (not recommended)" to "Disabled".

The Lan Manager authentication level must be set to send NTLMv2 response only, and to refuse LM and NTLM.

RMF Control: CM-6
Severity: High
CCI: CCI-000366
Version: 3.031
Vuln IDs: V-1153
Rule IDs: SV-25105r2_rule

The Kerberos v5 authentication protocol is the default for authentication for domains. NTLM which is less secure, is retained in later Windows versions for compatibility with standalone systems as well as applications that may still use it. Earlier versions of the LM/NTLM protocol are particularly vulnerable to attack and must be prevented.System Administrator

Fix: F-66961r1_fix

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> Security Options >> "Network security: LAN Manager authentication level" to "Send NTLMv2 response only\refuse LM & NTLM".

Ctrl+Alt+Del security attention sequence is disabled.

RMF Control: CM-6
Severity: Medium
CCI: CCI-000366
Version: 3.032
Vuln IDs: V-1154
Rule IDs: SV-25045r1_rule

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

Fix: F-92r1_fix

Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> “Interactive Logon: Do not require CTRL ALT DEL” to “Disabled”.

CCI: CCI-000213
Version: WINUR-000017
Vuln IDs: V-1155
Rule IDs: SV-25019r5_rule

Inappropriate granting of user rights can provide system, administrative, and other high level capabilities. The "Deny access to this computer from the network" right defines the accounts that are prevented from logging on from the network. In an Active Directory Domain, denying logons to the Enterprise Admins and Domain Admins groups on lower trust systems helps mitigate the risk of privilege escalation from credential theft attacks which could lead to the compromise of an entire domain. Local accounts on domain-joined systems must also be assigned this right to decrease the risk of lateral movement resulting from credential theft attacks. The Guests group must be assigned this right to prevent unauthenticated access.System Administrator

Fix: F-74857r2_fix

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> User Rights Assignment >> "Deny access to this computer from the network" to include the following. Domain Systems Only: Enterprise Admins group Domain Admins group Local account (see Note below) All Systems: Guests group Systems dedicated to the management of Active Directory (AD admin platforms, see V-36436 in the Active Directory Domain STIG) are exempt from denying the Enterprise Admins and Domain Admins groups. Note: Microsoft Security Advisory Patch 2871997 adds new built-in security groups, including "Local account", to Windows 7 for assigning permissions and rights to all local accounts.
