This just in from Brian Goldfarb:

J.D. Meier and team have been busy at work building awesome ASP.NET 2.0 security content -- I posted some links earlier on my blog (, but here is an excellent "Security Practices at a Glance." 

Specifically worth checking out is the "Index of Practices" which has all the links of solved problems. Bookmark it, learn it, love it :) and share it with everyone you know!
