I've spoken at a number of TechNet events recently at which I've mentioned the DTI report as a useful source of UK metrics for security breaches and risks. The latest report(released in 2004) is located at the following URL.

The report is released every other year at the UK's largest information security show - namely InfoSec. Many of our Security experts will be on hand both at the Microsoft stand and in the Pillar Room where we'll be hosting a free seminar programme.
