The container platform must prohibit password reuse for a minimum of 10 generations.
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 information system or application allows the user to consecutively reuse their password when that password has exceeded its defined lifetime, the result is a password that is not changed as per policy requirements. The references for this check are: NIST SP 800-53 :: IA-5 (1) (e) NIST SP 800-53A :: IA-5 (1).1 (v) NIST SP 800-53 Revision 4 :: IA-5 (1) CNSS 1253
Configure the container platform to prohibit password reuse for a minimum of five generations.
Review the container platform configuration to determine if it prohibits password reuse for a minimum of five generations. If the container platform does not prohibit password reuse for a minimum of five generations, this is a finding.
