SLEM 5 shadow password suite must be configured to enforce a delay of at least five seconds between logon prompts following a failed logon attempt.

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

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.

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
