Title

The SUSE operating system must enforce a delay of at least four seconds between logon prompts following a failed logon attempt. (Cat II impact)

Discussion

Limiting the number of logon attempts over a certain time interval reduces the chances that an unauthorized user may gain access to an account.

Check Content

Verify the SUSE operating system enforces a delay of at least four seconds between logon prompts following a failed logon attempt. Check that the SUSE operating system enforces a delay of at least four seconds between logon prompts following a failed logon attempt with the following command: > grep FAIL_DELAY /etc/login.defs FAIL_DELAY 4 If the value of "FAIL_DELAY" is not set to "4", "FAIL_DELAY" is commented out, or "FAIL_DELAY" is missing, then this is a finding.

Fix Text

Configure the SUSE operating system to enforce a delay of at least four seconds between logon prompts following a failed logon attempt. Add or update the following variable in "/etc/login.defs" to match the line below ("FAIL_DELAY" must have a value of "4" or higher): FAIL_DELAY 4
