Larry H. has been doing security research on the Macintosh platform for over 2 years (since mid 2006), with strong focus on kernel land security and implementation of proactive defense mechanisms for both Linux and the XNU kernel. Even though computers aren't his main occupation, he enjoys developing new and improving existent exploitation and IDS evasion techniques, as well as researching on secure OS design, security policy frameworks (MAC, RBAC, MLS, etc) and applied data mining. Even though this all sounds pretty serious, he enjoys humor for the banter as well as reading through the King James Bible quite frequently.
