I may have mentioned it a while back but it deserves repeating. There’s a (relatively) new information security magazine called Hackin9 that’s chock full of good material. It’s sort of like 2600 and then some. Definitely worth a read if you’re into staying up with the latest hacking tools and techniques.
“A business associate referred our company to Principle Logic when we were seeking a resource to perform vulnerability /penetration testing for our external and internal networks. We found Kevin Beaver to be professional, well informed, and easy to work with. His testing did not disrupt our networks, and his progress updates were timely.
His final report was very thorough and included security recommendations for our network environment. The executive leadership was so impressed with Kevin’s security expertise, they have extended their agreement to continue to perform periodic testing. We highly recommend Kevin Beaver and Principle Logic as a resource for network security testing.”
