Snort
Snort is an open source network intrusion prevention and
detection system utilizing a rule-driven language, which combines the
benefits of signature, protocol and anomaly based inspection
methods.
It can perform real-time traffic analysis, alerting, blocking
and packet logging on IP networks. It utilizes a combination
of protocol analysis and pattern matching in order to detect a
anomalies, misuse and attacks. It detects a variety of
attacks and probes, such as buffer overflows, stealth port scans, CGI
attacks, SMB probes, OS fingerprinting attempts, and much more.
Snort uses a flexible rules language to describe activity that
can be considered malicious or anomalous as well as an analysis engine
that incorporates a modular plugin architecture. Snort is
capable of detecting and responding in real-time, sending alerts,
performing session sniping, logging packets, or dropping
sessions/packets when deployed in-line.
Features include:
- 3 primary functional modes
- Packet Sniffer like tcpdump
- Packet logger (useful for network traffic debugging etc)
- Full blown network intrusion, detection, and prevention
system
- Performs TCP stream reassembly
- Stateful protocol analysis
- Handles IP dedragmentation
- Logs the full packets when alerts are generated
