Our (at the time) Head of R&D, Didi Barnes, created some security-related crosswords as part of a competition we held for the Infosecurity Europe Exhibition in Olympia in April 2004 and 2005. Didi has made them "interactive" and you can have a go at them on-line - why not try them and see how good you are! Didi is likely to post more when she gets respite from her usual tasks here at First Base Technologies (since she is now Chief Financial Officer)!
