Check Text ( C-89563r1_chk )
Check the value of the "FAIL_DELAY" variable and the ability to use it:

# grep FAIL_DELAY /etc/login.defs

The following result should be displayed:


If the value does not exist, or is less than "4", this is a finding.

Check for the use of "pam_faildelay":

# grep pam_faildelay /etc/pam.d/common-auth*

The following result should be displayed:

/etc/pam.d/common-auth:auth optional pam_faildelay.so

If the "pam_faildelay.so" module is not listed or is commented out, this is a finding.
Fix Text (F-96613r1_fix)
Add the "pam_faildelay" module and set the "FAIL_DELAY" variable.

Edit "/etc/login.defs" and set the value of the "FAIL_DELAY" variable to "4" or more.

Edit "/etc/pam.d/common-auth" and add a "pam_faildelay" entry if one does not exist, such as:

auth optional pam_faildelay.so
