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. WebUnable to detect zero-day attacks. 9 Q Explain an Anomaly-based IDS A An anomaly-based IDS compares patterns of traffic against a well-known baseline.

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.
