Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. If the information system or application 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.
Configure the operating system to prohibit password reuse for a minimum of five generations.
Verify the operating system prohibits password reuse for a minimum of five generations. If it does not, this is a finding.
