Details of InfoSec 2005 can be found @ http://www.infosec.co.uk - it's one of the largest information security shows in Europe. Many of the security vendors will be there together with thousands of your peers. Microsoft are hosting a free seminar programme(in the Pillar room) which will focus on practical advise to help you get more from Windows. We also have a large stand which will be manned by Technical people - sales people(from Microsoft at least!) are banned. We'll be happy to listen to descriptions of the problems you'd like to address and we'll explain in detail how to address them based on world class prescriptive guidance.
I believe that the event is free is you register in advance - check out http://www.infosec.co.uk for more information.
I hope to see you @ Olympia on 26th to 28th April.
