Sudheer,

I like to block all outgoing traffic in case that someone can take control
either from my firewall system or any other system in my network.

The firewall should be the most secure system in your network; however, like
any other system, it is still vulnerable to bugs and exploits.

If the firewall allows everything out, your system can turn out to be the
one used to attack other systems. It might bee too paranoid, but I like to
protect other people from having my systems attacking theirs.

Also, if you don't have a good system security policy, you might not realize
that your system was taken over until the gentleman with the nice black
suits
knock at your door  ....    =)

-- Just my two cents! maybe even less!
