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 Web Client go to Administration >> Single Sign-On >> Configuration >> Policies >> Lockout Policy. View the values for the lockout policies. The following lockout policy should be set at follows: Maximum number of failed login attempts: 3 If this account lockout policy is not configured as stated, this is a finding.

Fix text

From the vSphere Web Client go to Administration >> Single Sign-On >> Configuration >> Policies >> Lockout Policy. Click Edit. Set the Maximum number of failed login attempts to 3 and click OK.

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.
