Security
System and Software Architecture review. Focus on protection of user data, including personal and financial data. Threat analysis and mitigation techniques tailored by application and industry. Using a combination of in person review and code spelunking I can tell you where your systems are most vulnerable and what solutions best fit your company's needs.
Time
Accurate timekeeping has become increasingly important in many industries, including finance, manufacturing and telecommunications. As the leader of the Precision Time Protocol project I have a wealth of experience in designing and deploying systems to keep massive numbers of hosts well synchronized.
Open Source
I have coded and published several pieces of open source software, including work on the FreeBSD Operating System, Precision Time Protocol daemon, Conductor, Packet Construction Set and Packet Debugger . I am also a past President of the FreeBSD Foundation.
Books
The Design and Implementation of the FreeBSD Operating System, 2nd Ed. is the definitive work on one of the most popular, open source, kernels. The Kollected Kode Vicious is the first collection of my columns. You can also see my Amazon Author Page.
