Chrooted Snort on Solaris
This paper will focus on installing a Snort IDS on the Solaris operating system, and securing it in a chrooted environment. Snort is an easy to use, cost effective, lightweight IDS that compiles and runs on every major operating system. Snort has had one major security flaw in it's time, due to a RPC protocol buffer overflow, which is why we will chroot its installation.
The effect of chrooting a process minimizes the impact of future buffer overflows like this one. The IDS process would still likely crash, taking the IDS offline, but the hacker would not gain access due to the overflow because the chrooted environment would not contain a shell.
