## AI overview

The article examines how SnortML adds local machine-learning inference to Snort 3's intrusion-detection pipeline. It contrasts signature-based detection, which provides precise coverage for known exploits, with machine-learning detection aimed at identifying novel or modified attack behavior. It also places SnortML alongside the broader rise of agentic AI in network defense, while treating the two as developments operating at different architectural layers.

## Source excerpt

Signature-based detection has always known what it was looking for. Machine learning and autonomous agents are changing the question entirely, shifting from "does this match a known pattern?" to "does this actually make sense in context?"
