Check Text ( C-72479r1_chk )
Verify SSH provides users with feedback on when account accesses last occurred. Check that "PrintLastLog" keyword in the sshd daemon configuration file is used and set to "yes" with the following command: # 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-78599r2_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). Add the following line to the top of "/etc/pam.d/sshd": session required pam_lastlog.so showfailed Or 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.
