## プロジェクトの歴史と使われ方

Snort is a long-running open-source intrusion detection and prevention system whose command-line engine, rule language, and packaging history make it one of the canonical security tools in Unix and network-operations package collections.

### プロジェクトの歴史

Snort's official GPL page carries Martin Roesch copyrights beginning in 1998, and Snort's own site describes it as an open-source IPS capable of real-time traffic analysis and packet logging. The project evolved from a packet sniffer and logger into a rule-driven network IDS/IPS with community and subscriber rules.

Snort 3, also known in the repository README as Snort++, was officially released on January 19, 2021 as version 3.1.0.0 after more than seven years of development. The official announcement describes a ground-up rework with faster rules, more user control, multi-environment support, multi-threaded packet processing, Lua configuration, pluggable components, service autodetection, sticky buffers, and autogenerated reference documentation.

### 採用の歴史

Snort has a package-manager footprint because it is both a classic open-source security engine and an operational dependency for labs, appliances, training environments, and production sensors. The supplied package metadata lists Homebrew, Alpine, MacPorts, Nix, and Ubuntu packaging, while Snort.org points users to source releases, GitHub code, rule downloads, setup guides, and the Snort 3 manual.

### 使われ方

Snort is used as a packet sniffer, packet logger, network intrusion detection system, and inline prevention system. Snort 3 users typically build or install the engine, configure Lua files such as `snort.lua`, add rule sets, validate the configuration, then run against live interfaces or PCAP files with alert output suitable for analysts and automation.

### パッケージ好きにとっての重要性

Package nerds care about Snort because it exercises nearly every hard part of packaging security software: libpcap/DAQ integration, LuaJIT configuration, C++ build requirements, rule data that changes independently from the engine, optional acceleration libraries, service files, sample configs, and upgrades between major rule-engine generations.

### タイムライン

- 1998: Official GPL page lists Martin Roesch copyrights beginning with Snort's early releases.
- 2014: Snort 3-era copyright line begins under Cisco and affiliates in official version-output examples.
- 2021-01-19: Snort 3 version 3.1.0.0 officially released.
- 2026: Snort blog announces end-of-life for older Snort 2 and Snort 3 rule-support versions and encourages use of current Snort 3 packages.

### Related projects

- Snort is commonly discussed alongside tcpdump for packet sniffing, libpcap for capture, DAQ for packet I/O, Cisco Talos for rule development, and other IDS/IPS systems such as Suricata.
