Recommended Kernel Patch

(1/1)

Sephiroth:
Just for the kernel compiling guru's i stumbled across a few patches you might be intrested it

GRSecurity (http://www.grsecurity.net) for kernel version 2.4.17, lots of good secruity patches. Protects against TONS of exploits.

Preempt (http://www.tech9.net/rml/linux/) for kernel 2.4.17 +(?) makes the kernel less laggy...

lost:
if you want a security patch check out what the NSA has done with SELinux.  It rules.  Finally context roles for linux.

dbl221:

While your at it install these libraries in the following order for all you "security" monitoring and evaluation

1) libpcap
2) libnet
3) libnids

I also like nmap

 

voidmain:
If you want a good scanner for scanning vulnerabilities I think "nessus" is one of the best.  See http://www.nessus.org
