Expired Certificate



If an expired certificate is used for HTTPs, administrators can't be assured of the connection security. The sessions could be compromised including being subject to a MITM (man-in-the-middle) attack. The SFOS offers a selection of automatic update intervals.


If a CA expires or is compromised, your firewall can regenerate it. To regenerate a CA, do as follows:

  1. Go to Certificates > Certificate authorities.
  2. To regenerate the default certificate, go to the Manage column and click Regenerate certificate.
