Profile bio

About Daniel Teal

I am a consummate computer security professional. I have watched the security field grow over my long career and am accomplished in many of the facets of security today. As a US Air Force Officer in the early 1990s, I helped develop the technologies and techniques for offensive and defensive information warfare. I have long proposed that you cannot adequately secure something unless you know how to attack it. I have developed penetration testing tools, researched and developed host and network based intrusion detection systems, tested the efficacy of security products, architected next generation security products, and mentored security development teams. My primary objective is to develop advanced security products to stop the threats of today and mitigate the threats of tomorrow.

Listed skills include Computer Security, Network Security, Security, Penetration Testing, and 45 others.
