Check Text ( C-42359r675250_chk )
At the command line, execute the following command:

# grep pam_faildelay /etc/pam.d/system-auth|grep --color=always "delay="

Expected result:

auth      optional    pam_faildelay.so  delay=4000000

If the output does not match the expected result, this is a finding.
Fix Text (F-42318r675251_fix)
Open /etc/pam.d/system-auth with a text editor.

Remove any existing "pam_faildelay" line and add the following line at the end of the file:

auth      optional    pam_faildelay.so  delay=4000000
