Subject: Application level firewall

Is there any sort of application level firewall for linux?  Something
like Zone alarm where you can trust an application?  I think that
openBSD has something that allows you to choose which system calls a
program can run.

The idea would be to restrict a bind call and connect call using kernel
modules unless the program is in a config file.  It would make it easier
(i would think) to lockdown a computer for outgoing connections as well
as add a new layer of security.
