Is it compulsory to use costume application in rule

L2 Linker

We have used application over ride for specific app and name is "server_443" and its working fine, we are able to see that application is showing in traffic logs. In access rule i have allowed any application from trust to untrust zone.


My query is that is it compulsory to use costume application in security rule?

Its not compulsory but yes you should have at least security policy on your firewall which will allow traffic on it. If you have app-id based security policies, you need to have security policy which will allow new custom app. As you have security policy which is allowing any application so traffic is getting allowed on custom-application too. If you really want to have application specific security policies, you can add specific applications under security policies. While doing so you really need to check all the traffic passing through your firewall and make sure it shouldn't drop anything which is already working through any application security policy.


Hope it helps!
