Information
The vCenter Server must require an administrator to unlock an account locked due to excessive login failures.
GROUP ID: V-258933RULE ID: SV-258933r961368
By requiring that Single Sign-On (SSO) accounts be unlocked manually, the risk of unauthorized access via user password guessing, otherwise known as brute forcing, is reduced. When the account unlock time is set to zero, a locked account can only be unlocked manually by an administrator.
NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.
Solution
From the vSphere Client, go to Administration >> Single Sign On >> Configuration >> Local Accounts >> Lockout Policy.
Click "Edit".
Set the "Unlock time" to "0" and click "Save".
