Snort
Cisco
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. Once downloaded and configured, Snort rules are distributed in two sets: The “Community Ruleset” and the “Snort Subscriber Ruleset.” The Snort Subscriber Ruleset is developed, tested, and approved by Cisco Talos. Subscribers to the Snort Subscriber Ruleset will receive the ruleset in real-time as they are released to Cisco customers. -
