Description
Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. To meet password policy requirements, passwords need to be changed at specific policy-based intervals. If the network device allows the user to consecutively reuse their password when that password has exceeded its defined lifetime, the end result is a password that is not changed as per policy requirements.

Verify the BIG-IP appliance is configured to use a properly configured authentication server that prohibits password reuse for a minimum of five generations. Navigate to the BIG-IP System manager >> System >> Users >> Authentication. Verify "Authentication: User Directory" is configured for an approved remote authentication server that prohibits password reuse for a minimum of five generations. If the BIG-IP appliance is not configured to use an associated authentication server that prohibits password reuse for a minimum of five generations, this is a finding.
