Do I require a security rule if I create an application override rule?

yes, you will need a security policy rule to allow/block the custom app from your app override rule.

Not applicable

Hi lisiecki,

If we see in, there will be no scanning performed on the session in Application Override.

I have a related question about application override.

Let's say we created custom app my-telnet.

Then we created an application override rule which identifies traffic let's say from network to host on port 24 as my-telnet

In security rules we have a more general rule allowing traffic from to for all applications on all ports. (so basically custom application my-telnet is not used anywhere in security policy)

Will session from to host on port 24 be recognised as my-telnet?

you will need to have the specific rule before the general rule for it to be recognized.  Firewall rules are processed from top down and stop processing on the first match.

Thanx for the answer but I think you're wrong.

I've decided to test it; I've created 'myapp' with no protocol/port.. definition.

I've created application override rule saying anything from certain IP address to destination port 222 is 'myapp'

I've created security policy with one rule which allows all traffic for all apps on any port.

Session from the IP address defined in application override rule to port 222 was recognised as 'myapp'
