Build an IDS with Snort, Shadow, and ACID

NewsForge | Build an IDS with Snort, Shadow, and ACID
“Every organization understands the importance of using a firewall to protect its assets. But what happens if someone finds a hole in the wall? What if the infiltrator is actually someone from within your organization who wants to access information that he shouldn’t? To cover those contingencies, you need an intrusion detection system (IDS) to complement your firewall. Fortunately, with a minimum amount of time and money you can set up an IDS with open source tools such as Snort, Shadow, and ACID.“
