The ESXi host must be configured with an appropriate maximum password age.

The older an ESXi local account password is, the larger the opportunity window is for attackers to guess, crack or reuse a previously cracked password. Rotating passwords on a regular basis is a fundamental security practice and one that ESXi supports.

From the vSphere Client, go to Hosts and Clusters.

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

Select the "Security.PasswordMaxDays" value and verify it is set to "90".

or

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

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

If the "Security.PasswordMaxDays" setting is not set to "90", this is a finding.

From the vSphere Client, go to Hosts and Clusters.

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

Click "Edit". Select the "Security.PasswordMaxDays" value and configure it to "90".

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

Get-VMHost | Get-AdvancedSetting -Name Security.PasswordMaxDays | Set-AdvancedSetting -Value 90
