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

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.

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

Unauthorized users will not be granted the "Act as part of the operating system" user right.
Inappropriate granting of user rights can provide system, administrative, and other high level capabilities.
This is a Category 1 finding as accounts and 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

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-1, IAIA-2

Minimum password age does not meet minimum requirements.

Password uniqueness does not meet minimum requirements.

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

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

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 AdministratorECSC-1

Unencrypted password is sent to third-party SMB server.
Some non-Microsoft SMB servers only support unencrypted (plain text) password authentication. Sending plain text passwords across the network, when authenticating to an SMB server, reduces the overall security of the environment. Check with the vendor of the SMB server to see if there is a way to support encrypted password authentication.HKSystem AdministratorECCT-1, ECCT-2

The Send download LanMan compatible password option is not 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. 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 AdministratorIAIA-1, IAIA-2

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

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 local administrator 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 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 administrator 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 AdministratorECLP-1
