Linux RHEL-10-600600

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.

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
