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 (http://blogs.msdn.com/bgold/), 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!
