To check the status of SSL certificates on vCenter Server, open the vSphere Client and connect to the vCenter Server and log in. In the Security Warning dialog, click View Certificate and check the Valid from mm/dd/yy to mm/dd/yy field for the expiry information. Click OK. If unable to determine the certificate status from the certificate details, ask the SA if there is a site procedure to ensure the monitoring and removal of expired certificates from the vCenter Server Windows host. Use this procedure to check the vCenter Server/host for the presence of expired certificates. If a procedure does not exist and/or expired certificates are found, this is a finding.
