Vulnerability discussion

By limiting the number of failed login attempts, the risk of unauthorized access via user password guessing, otherwise known as brute-forcing, is reduced. Limits are imposed by locking the account.

Check content

From the vSphere Client select the ESXi Host and go to Configuration >> Advanced Settings. Select the Security.AccountUnlockTime value and verify it is set to 900. or From a PowerCLI command prompt while connected to the ESXi host run the following command: Get-VMHost | Get-AdvancedSetting -Name Security.AccountUnlockTime and verify it is set to 900. If the Security.AccountUnlockTime is set to a value other than 900, this is a finding.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
