daq

Data Acquisition abstraction library for snort 2.9+

Snort 2.9 introduces the DAQ, or Data Acquisition library, for packet I/O. The DAQ replaces direct calls to PCAP functions with an abstraction layer that facilitates operation on a variety of hardware and software interfaces without requiring changes to Snort. It is possible to select the DAQ type and mode when invoking Snort to perform PCAP readback or inline operation, etc. The DAQ library may be useful for other packet processing applications and the modular nature allows you to build new modules for other platforms.
