Discussion

By enforcing a reasonable unlock timeout after multiple failed logon attempts, the risk of unauthorized access via user password guessing, otherwise known as brute forcing, is reduced. Users must wait for the timeout period to elapse before subsequent logon attempts are allowed.

From the vSphere Client, go to Hosts and Clusters.

Select the ESXi Host >> Configure >> System >> Advanced System Settings.

Select the "Security.AccountUnlockTime" value and verify it is set to less than "900" and not "0".

or

From a PowerCLI command prompt while connected to the ESXi host, run the following command:

Get-VMHost | Get-AdvancedSetting -Name Security.AccountUnlockTime

If the "Security.AccountUnlockTime" setting is less than 900 or 0, this is a finding.
