When you first boot up the firewall or Panorama,
it automatically generates a default certificate that enables HTTPS
access to the web interface and XML API over the management (MGT)
interface and (on the firewall only) over any other interface that
supports HTTPS management traffic (for details, see
Use Interface Management Profiles
to Restrict Access). To improve the security of inbound management
traffic, replace the default certificate with a new certificate
issued specifically for your organization.
You cannot
view, modify, or delete the default certificate.
