Which type of filtering is IDSs known to perform?

Explanation:
Deep packet inspection is the technique IDSs use to examine not just the packet headers but also the actual data payloads carried inside each packet. By decoding application-layer protocols, matching content against signatures, and sometimes reassembling TCP streams, the IDS can detect threats that hide within legitimate-looking traffic. While analyzing the sequence of packets over time (packet stream analysis) can aid detection, the primary and most recognized filtering method for IDSs is inspecting the payload content itself, i.e., deep packet inspection.
