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 must 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 per policy requirements.

ℹ️ Check
From the vSphere Client, go to Administration >> Single Sign On >> Configuration >> Local Accounts >> Password Policy. View the value of the "Restrict reuse" setting. Restrict reuse: Users cannot reuse any previous 5 passwords If the password policy is not configured with a "Restrict reuse" policy of "5" or more, this is a finding.

✔️ Fix
From the vSphere Client, go to Administration >> Single Sign On >> Configuration >> Local Accounts >> Password Policy. Click "Edit". Set the "Restrict reuse" to "5" and click "Save".
