Snort 2

Snort is the foremost Open Source Intrusion Prevention System (IPS) in the world. Snort IPS uses a series of rules that help define malicious network activity and uses those rules to find packets that match against them and generates alerts for users.

Snort can be deployed inline to stop these packets, as well. Snort has three primary uses: As a packet sniffer like tcpdump, as a packet logger — which is useful for network traffic debugging, or it can be used as a full-blown network intrusion prevention system. Snort can be downloaded and configured for personal and business use alike.

While users can still utilize the legacy Snort 2 system, we highly encourage upgrading to Snort 3 for sweeping upgrade featuring improvements and new features resulting in enhanced performance, faster processing, improved scalability for your network and a range of 200+ plugins so users can create a custom set-up for their network.
