Rule IDs: SV-254285r958736_rule

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.

Fix: F-57721r848670_fix

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Account Policies >> Account Lockout Policy >> Account lockout duration to "15" minutes or greater. A value of "0" is also acceptable, requiring an administrator to unlock the account.

b

Windows Server 2022 must have the number of allowed bad logon attempts configured to three or less.

RMF Control: AC-7
Severity: M
CCI: CCI-000044
Version: WN22-AC-000020
Vuln IDs: V-254286
Rule IDs: SV-254286r958388_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 normal user logon.

Fix: F-57722r848673_fix

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

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.

Fix: F-57723r848676_fix

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Account Policies >> Account Lockout Policy >> Reset account lockout counter after to at least "15" minutes.

b

Windows Server 2022 password history must be configured to 24 passwords remembered.

RMF Control
Severity: M
CCI: CCI-004061
Version: WN22-AC-000040
Vuln IDs: V-254288
Rule IDs: SV-254288r1000156_rule

A system is more vulnerable to unauthorized access when system users recycle the same password several times without being required to change 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.

Fix: F-57724r848679_fix

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

b

Windows Server 2022 maximum password age must be configured to 60 days or less.

Version: WN22-AC-000050
Vuln IDs: V-254289
Rule IDs: SV-254289r1051091_rule

The longer a password is in use, the greater the opportunity for someone to gain unauthorized knowledge of the passwords. Scheduled changing of passwords hinders the ability of unauthorized system users to crack passwords and gain access to a system.

Fix: F-57725r848682_fix

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Account Policies >> Password Policy >> Maximum password age to "60" days or less (excluding "0", which is unacceptable).

b

Vuln IDs: V-254290
Rule IDs: SV-254290r1051092_rule

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.

Fix: F-57726r848685_fix

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Account Policies >> Password Policy >> Minimum password age to at least "1" day.

b

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 compromising the device, information, or the local network.

Fix: F-57727r848688_fix

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Account Policies >> Password Policy >> "Minimum password length" to "14" characters.

The use of complex passwords increases their strength against attack. The built-in Windows password complexity policy requires passwords to contain at least three of the four types of characters (numbers, uppercase and lowercase letters, and special characters) and prevents the inclusion of user names or parts of user names. Satisfies: SRG-OS-000069-GPOS-00037, SRG-OS-000070-GPOS-00038, SRG-OS-000071-GPOS-00039, SRG-OS-000266-GPOS-00101

Version: WN22-AC-000090
Vuln IDs: V-254293

Storing passwords using reversible encryption is essentially the same as storing clear-text versions of the passwords, which are easily compromised. For this reason, this policy must never be enabled.

Fix: F-57729r848694_fix

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Account Policies >> Password Policy >> Store passwords using reversible encryption to "Disabled".

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. Collecting this data is essential for analyzing the security of information assets and detecting signs of suspicious and unexpected behavior. Enabling "Include command line data for process creation events" will record the command line information with the process creation events in the log. This can provide additional detail when malware has run on a system.

In Kerberos, there are two 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 start up under a specified user account, users must always get a TGT first and then get Service Tickets to all computers and services accessed.

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. 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. Satisfies: SRG-OS-000112-GPOS-00057, SRG-OS-000113-GPOS-00058

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.

The risk of an attacker pulling this off can be decreased by implementing strong physical security measures to protect the network infrastructure.
