Snort is a free open source network intrusion detection system (IDS) and intrusion prevention system (IPS)[4] created in 1998 by Martin Roesch, founder and former CTO of Sourcefire.[5][6] Snort is now developed by Cisco, which purchased Sourcefire in 2013.[7][8][9]
In 2009, Snort entered InfoWorld's Open Source Hall of Fame as one of the "greatest [pieces of] open source software of all time".[10]
Uses
Snort's open-source network-based intrusion detection/prevention system (IDS/IPS) has the ability to perform real-time traffic analysis and packet logging on Internet Protocol (IP) networks. Snort performs protocol analysis, content searching and matching.
The program can also be used to detect probes or attacks, including, but not limited to, operating system fingerprinting attempts, semantic URL attacks, buffer overflows, server message block probes, and stealth port scans.[11]
Snort can be configured in three main modes: 1. sniffer, 2. packet logger, and 3. network intrusion detection.[12]
Sniffer Mode
The program will read network packets and display them on the console.
Packet Logger Mode
In packet logger mode, the program will log packets to the disk.
Network Intrusion Detection System Mode
In intrusion detection mode, the program will monitor network traffic and analyze it against a rule set defined by the user. The program will then perform a specific action based on what has been identified.[13]
Third-party tools
There are several third-party tools interfacing Snort for administration, reporting, performance and log analysis:
- Snorby – a GPLv3[14] Ruby on Rails application
- BASE
- Sguil (free)
