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 SLEM 5 enforces a delay of at least five seconds between logon prompts following a failed logon attempt with the following command:

     > grep -i fail_delay /etc/login.defs
     FAIL_DELAY 5

If the value of "FAIL_DELAY" is not set to "5" or greater, the line is commented out, or the line is missing, this is a finding.

Fix Text

Configure SLEM 5 to enforce a delay of at least five seconds between logon prompts following a failed logon attempt.

Add or modify the following line in the "/etc/login.defs" file:

FAIL_DELAY 5
