ProPolice: http://www.research.ibm.com/trl/projects/security/ssp/ You need to have a GCC that has stack-smash-protector (SSP) functionality. You can see if your GCC does by issuing the following command: gcc -v If your gcc has SSP built in, it will output something like this: gcc version 3.3.4 20040623 (Gentoo Hardened Linux 3.3.4-r1, ssp-3.3.2-2, pie-8.7.6) The "ssp" and "pie" (Position-Independent Executable) are what you want to see. During compilation you want to see something like "fstack-protector" in the compilation output. You can Google for more info, but those are the basics. Grsecurity and PaX can be found here: http://grsecurity.net/ http://pax.grsecurity.net/ Those are patches for the Linux kernel and I highly recommend that you read the info available on grsecurity's site. The "features" page has quite a list describing what grsecurity does: http://grsecurity.net/features.php On 10/26/05, Ron Jenkins <rjenkins@dibr.net> wrote:
