Check Text (C-281212r1166588_chk)
Verify RHEL 10 includes the use of the pam_faillock.so module in the "/etc/pam.d/system-auth" file:
$ sudo grep pam_faillock.so /etc/pam.d/system-auth
auth required pam_faillock.so preauth
auth required pam_faillock.so authfail
account required pam_faillock.so
If the pam_faillock.so module is not present in the "/etc/pam.d/system-auth" file with the "preauth" line listed before pam_unix.so, this is a finding.
If the system administrator can demonstrate that the required configuration is contained in a PAM configuration file included or substacked from the "system-auth" file, this is not a finding.
Fix Text (F-85678r1166587_fix)
Configure RHEL 10 to include the use of the pam_faillock.so module in the "/etc/pam.d/system-auth" file.
If PAM is managed with authselect, enable the feature with the following command:
$ sudo authselect enable-feature with-faillock
Otherwise, add/modify the appropriate sections of the "/etc/pam.d/system-auth" file to match the following lines:
Note: The "preauth" line must be listed before pam_unix.so.
auth required pam_faillock.so preauth
auth required pam_faillock.so authfail
account required pam_faillock.so
