Information
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.
NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.
Solution
Configure the BIG-IP appliance to use a properly configured authentication server to prohibit password reuse for a minimum of five generations.
