I work for IBM as a Consulting Security Specialist, based in central London. I have worked on a number of IBM red books over the years, but most recently I has part of the team who wrote Integrating IBM Security and SAP Solutions.
Over the years I have worked hands-on with most of the current IBM Security Systems products (see https://www.ibm.com/security/). Before that I worked on IBM’s mainframe cryptographic products and as a networking specialist. Before joining IBM I worked as a software engineer, writing real-time communications software for networking products and telephone exchanges in the US and the UK. (At the risk of stating the obvious, the postings on this site are my own and don’t necessarily represent IBM’s positions, strategies or opinions.)
(I studied Engineering at the University of Cambridge, but that was a long time ago.)
