Application Dependencies

L1 Bithead

Hi all,

First time post.


If you add all the required dependent applications to security policy (e.g. for Skype: msn-base, ssl & web-browsing), does this then allow all of those apps out dependent of if the primary Skype app is being used for that policy?

i.e does it allow msn-base, ssl & web-browsing from the source IP address to the destination address even if Skype isn't the primary Application?

But you can limit down destination where connections can be done with "Destination",  "URL Category" and "URL Profile".

But you'd need to have a valid URL filtering license for this.


It's as I expected but I wanted to get it confirmed.


Thanks for the reply.

Some applications work even without all the dependencies allowed. It's worth to try.

The apps that can function without their dependencies in the security policy, will have the dependencies listed as 'implicitly uses'. The corresponding dependency AppID decoder will be triggered, but the dependency apps do not need to be allowed in the security policy for the intended app to function properly

You can create custom URL categories without license and use those.
