Article - Tunneling out of Corporate Networks

[foldingstock]

Being a user and fan of OpenBSD, I often check undeadly.org, an unofficial OpenBSD journal site. Recently, a five-part article was written by Mark Uemura, titled "Tunneling out of Corporate Networks." These articles detail some of the dangers of corporate networking as well as preventative maintenance that can be done. Mark did a good job of showing the other side of networking, where the biggest threat is not always what is coming into the network, but what is going out from within. I found these articles to be very informative.

It is an interesting read for anyone in this field or anyone wanting to learn more about networking. Although this is an OpenBSD article, the concepts are not OpenBSD-specific.

I am a noob when it comes to stuff like this so I found the articles to be very interesting and helpful. I am always looking for new techniques for tunneling out my school's firewall that maybe less detectable or faster.
