Should HAL expose firewall events?

[David D. Hagood]

Should firewall events, specifically outbound connection requests, be exposed 
via HAL?

I was thinking of programs like ZoneAlarm under Windows - when configured to, 
they can notify the user of a program attempting to connect to a network 
resource via a popup from the toolbar.

Since the Linux kernel has the ability to perform outbound connection filtering, 
would it make sense for there to be a module that would be notified by the 
kernel when a program first attempts to access a network resource. Then HAL 
could notify a user-space UI program that would ask the user about the access.

Of course, the other side of this question - the question of how the user 
allows/disallows access and how that information makes it back to the kernel 
would also need to be answered - and perhaps that answer would preclude HAL 
being in the loop at all.

I'm just trying to start discussion here - I am not (yet!) looking at doing 
anything about this until folks have thought about it.
