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. If the "Restrict reuse" policy is not set to "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", enter "5" as the "Restrict reuse" setting, and click "OK".
