Can snort catch zero-day network attacks

WebSnort can catch zero-day attacks to some extent, but it's not guaranteed. Snort relies on a signature-based detection system, which means it needs to have a signature for a particular attack in its database to detect it. Explanation: If an attack has never been seen before, there won't be any signature for it, and Snort won't be able to detect it. Dec 18, 2024 ·

Webvulnerability. A zero-day attack path is a multi-step attack path that includes one or more zero-day exploits. A key insight in dealing with zero-day attack paths is to analyze the chaining effect. Typically, it is not very likely for a zero-day attack chain to be 100% zero-day, namely having every exploit in the chain be a zero-day exploit.
