Re: Protecting Linux



I would like to use Udi's question to point out a security extension
for Linux kernels (2.2.x and 2.0.x) that offers some interesting features 
such as restricted Linx and FIFOs in /tmp, non-executable
user stack area and more. The addon can be found at:
http://www.openwall.com/linux/
