I have a Firewall,whose Outside interface is connected to a ISP with a Public IP address,now I want to protect this Outside interface.How can I do this?Basically it is like a Hardening the Firewall or a Router which is directly exposed to global network.
Your firewall is already providing perimeter security but you may still provide another layer of security protection in your edge router facing internet, I personally use the examples provided in these links.
Actually your firewall already provides functions to protect a outside interface.As you know,Traffics originating from inside should be allowed by a firewall. It will deny all traffics originating from outside unless you want to allow them.One thing when you enable IOS firewall on a router you need to manually configure an acl to deny traffics from outside-to-inside.
