Is virtual routing the “anti-matter” of network security?
This post from the Rational Security blog* presented a convincing case as to why that might be so. It was dated December 2008. I don’t know if virtual routing is safer now, or not.
Meanwhile, for those interested in routing as depicted in the photo, I found a good article about LAN switches. It explains quite clearly the difference between a router and a switch.
*The Rational Security blog has since departed TypePad (as of 2009). It has a slightly altered name, and is now The Rational Survivability blog.
