Security, Security & Security..
Just in case you didn't know, we've re-vamped our local security site www.microsoft.com/ireland/technet/security it now includes some great links to useful info & tools (like the Microsoft Security Assessment Tool (MSAT) - It will help identify processes, resources, and technologies that are designed to promote good security planning and risk mitigation practices within your organization). There's also links to some good training, including the Top 10 security related webcasts as voted on by our TechNet audience (you).
Anyway, I encourage you to have a look and to have a 'play' with the MSAT.
