Login Banner on Fortigate Firewalls

Not only is it good InfoSec Hygiene but most regulatory bodies require login banners.  With the Fortigate, it is easy to set up.  It will require a command line entry and then a GUI modification.  Her we go.

  1. Go to System
  2. Replacement Messages
  3. Choose the Extended View
  4. Enter pre and hit the search icon

You will then find..
