As the Chief Technology Officer at SecureLogix, I manage our technology roadmap, work with our strategic customers, perform security research, monitor for new threats, and architect our security solution. I am actively performing VoIP/UC security research, especially in the area of Telephony Denial of Service (TDoS), authentication/fraud, and call spoofing. I have also managed our engineering team for most the history of SecureLogix and directed the development of our voice security products. I have been working in the software industry for over 20 years. Most recently, I have been working in the voice/VoIP/Unified communications (UC) security and network industry. As CTO, I am focused on identifying new voice/VoIP/UC security threats, performing research including development of testing/attack tools, educating our customers and partners on these threats, and developing commercial solutions. I am also working with the Department of Homeland Security (DHS) on multiple research projects, focused on complex TDoS attacks and other security issues in critical environments such as banks and Next Generation 911 centers. I have led multiple additional research efforts in the area of voice, VoIP, and UC security. I have also developed a number of SIP attack tools as part of this research and to support the books I have written (Hacking Exposed: VoIP – 2006 and Hacking Exposed: UC and VoIP – 2013).
