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

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 users to crack passwords and gain access to a system.HKSystem Administrator
SV-25010r2_rule
4.012
CCI-000198

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-25008r3_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

CCI-000366
MEDIUM
The built-in guest account must be renamed.
The built-in guest account is a well-known user account on all Windows systems and, as initially installed, does not require a password. This can allow access to system resources by unauthorized users. Renaming this account to an unidentified name improves the protection of this account and the system.System Administrator

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. 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

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

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

The Lan Manager authentication level must be set to send NTLMv2 response only, and to refuse LM and NTLM.
The Kerberos v5 authentication protocol is the default for authentication 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
SV-25045r1_rule

CCI-000366
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 Administrator

The Deny access to this computer from the network user right on workstations must be configured to prevent access from highly privileged domain accounts and all local accounts on domain systems and unauthenticated access on all systems.
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

The Server Message Block (SMB) v1 protocol must be disabled on the SMB server.
SMBv1 is a legacy protocol that uses the MD5 algorithm as part of SMB. MD5 is known to be vulnerable to a number of attacks such as collision and preimage attacks as well as not being FIPS compliant.
Disabling SMBv1 support may prevent access to file or print sharing resources with systems or devices that only support SMBv1. File shares and print services hosted on Windows Server 2003 are an example, however Windows Server 2003 is no longer a supported operating system. Some older network attached devices may only support SMBv1.
