Verify SSH provides users with feedback on when account accesses last occurred with the following command: $ sudo grep -i printlastlog /etc/ssh/sshd_config PrintLastLog yes If the "PrintLastLog" keyword is set to "no", is missing, or is commented out, this is a finding.

Fix Text (F-56368r824218_fix)
Configure SSH to provide users with feedback on when account accesses last occurred by setting the required configuration options in "/etc/pam.d/sshd" or in the "sshd_config" file used by the system ("/etc/ssh/sshd_config" will be used in the example) (this file may be named differently or be in a different location if using a version of SSH that is provided by a third-party vendor). Modify the "PrintLastLog" line in "/etc/ssh/sshd_config" to match the following: PrintLastLog yes The SSH service must be restarted for changes to "sshd_config" to take effect.
