It's still extremely early post public release of Leopard and the tires are still in need of some swift kicks. At least those of us who were under NDA with regards to Leopard can now speak more freely.

I found the following Tidbits article which begins a discussion about the security improvements and features in Leopard:

http://db.tidbits.com/article/9251

Specifically it discusses Time Machine, Library Randomization (a.k.a. Memory Randomization), improved IPFW, application sandboxing, Keychain enhancements, SMB packet signing, guest accounts, and more.

In an article posted yesterday, they discuss an issue reported by Open Door Networks with the "Back to My Mac" feature: http://db.tidbits.com/article/9269
