True value of a certificate indeed, but most certificate programs also offer a training component, and training someone on all these theorys is going to be complicated. What this starting to sound like is a Bachelors Degree, or a Diploma rather then a certificate. Do you really think someone with no knowledge of networking could be taught all of this in under a year? Depending on how long it would take to learn all the theories is what I'd use as a judge for the reward at the end of the tunnle. A year or less is a certification, Two years or less is a College Diploma, and Four years or less is a Bachelor Degree. Oh how nice it would be to have a Bachelor Degree in computer networking, right now most universities only offer Computer Engineering (hardware) or Computer Science (software) and nothing to connect the software to the hardware to another hardware to another software! End of rant...

Dan,

In your article you wrote why it is important to block TCP 53 on a firewall because it is a DNS port. Well, UDP 53 is used for DNS since it is a connectionless request, and not connection oriented in nature.

I hope you're ready for the deluge... you might want to do a google on tcp 53 before you post things like that...
