The blog is run by Bruce Schneier, author of eight books including Beyond Fear: Thinking Sensibly about Security in an Uncertain World. He's also authored Secrets & Lies: Digital Security in a Networked World, which Bill reviews and recommends. Bruce also has a Crypto-Gram Newsletter you can subscribe to.
Recent interesting postings (to me, anyway) include:
- ChoicePoint Says "Please Regulate Me" -- If you haven't heard about the recent ChoicePoint debacle, you should.
- Telephone Monitoring While on Hold -- Oh great! (sigh)
Unfortunately, he doesn't seem to have any material that's Java- or J2EE-specific, but his stuff does seem to be a good way to learn about security in general.
