“The firewall threat you don’t know”
Are you placing active filters on data leaving?
The purpose of a firewall has been burned into the head of just about every person who uses the Internet, and the thought of functioning without protection from the bad people is sheer lunacy.
However, nearly all firewalls are unidirectional. They may protect you from nefarious pokes and prods from the nether regions of the Internet, but they’ll happily ship out any data you send from the inside. Only at the higher levels of enterprise IT do you see active filters for data leaving the network.
Paul Venezia makes a great point at the end:
As in so many facets of IT, to be forewarned is to be forearmed. The
quest for true network security and visibility is an ongoing struggle,
and even with all the notice in the world, there’s no winning this arms
race. But that doesn’t mean we can just quit. If you’re not watching
your outbound traffic now, plan on doing so as soon as possible. Whether
you start with something as “simple” as NTop or go for the big guns like the NIKSUN device, it’s a worthwhile investment of time and money — kinda like firewalls.
