Ever since he saw the movie TRON, Phil has been fascinated with computers, mainframes especially. Throughout his career he's had the chance to review mainframe security at various large organizations. He has worked in IT security for 9 years but ever since he learned you could emulate your own mainframe he's been knee deep in JCL, print queues and OMVS. Some people build toy trains, others model airplanes, but Phil's hobby is mainframe security. He has given a talk about mainframe security at BSidesLV, has been interviewed for podcasts and maintains a blog about mainframe security research.
