Use a Warning Banner
To properly secure a machine, you need to supply a warning banner. The banner doesn’t actually do anything to protect the router, but it does warn people who are connecting to the router that unauthorized access is taken seriously. That way, they can’t use the excuse that they didn’t know. It’s a good idea to ask for legal help in crafting an appropriate message.
The following commands create a warning banner:
! Apply a warning banner.
! Seek legal advice to craft a banner to properly protect your network
