RedHat to Add ExecShield, NX and Other Security Technologies in Next Update

I just read this whitepaper about new security features in RedHat Enterprise Linux Update 3. I use this distro extensively at work, and it's pretty good. I'm happy to see that NX support, ExecShield and other technologies they've already added to Fedora will finally be coming to RHEL.

There's a section at the end of the paper that claims these additional security measures would have stopped 75% of all the security issues for which patches were released from November 2003 to August 2004. That's a pretty impressive number. Of course, you still need to apply the vendor security patches in a timely fashion, but this looks to be a very handy safety net.
