## プロジェクトの歴史と使われ方

LibDAQ is Snort's Data Acquisition library, the packet I/O abstraction layer that lets Snort and related packet-processing tools talk to pcap files, live interfaces, inline packet paths, and platform-specific capture back ends.

### プロジェクトの歴史

Snort documentation says Snort 2.9 introduced DAQ to replace direct libpcap calls with an abstraction layer. The Snort 3 LibDAQ repository continues that idea with base modules and wrapper modules that compose into DAQ instances.

### 採用の歴史

LibDAQ is packaged separately because Snort users often need to build or install it before Snort itself, choose module directories, and line up the correct Snort 2 or Snort 3 DAQ version on machines where both generations coexist.

### 使われ方

In practice, users install LibDAQ, point Snort at the module directory when needed, list available modules with snort --daq-list, and then run Snort in passive, inline, or pcap-readback modes depending on the selected DAQ module.

### パッケージ好きにとっての重要性

LibDAQ is a package-manager boundary object: it is not the IDS itself, but versioning, module paths, kernel/network dependencies, and build options can decide whether Snort can capture packets at all.

### タイムライン

- 2010: Snort 2.9 documentation introduced DAQ as a replacement for direct libpcap calls.
- 2019: Early Snort 3 LibDAQ issue history shows separate packaging and configure/build questions.
- 2021: LibDAQ 3.0.x changelog entries document Snort 3-era module and API evolution.

### Related projects

- LibDAQ is closely tied to Snort 2, Snort 3, libpcap, Linux AF_PACKET, netfilter queue, netmap, and other packet acquisition paths used by intrusion detection and prevention deployments.
