Denial-of-Service aims to exhaust resources and make a service unavailable to legitimate users, not to camouflage attack traffic inside a flood of IDS alerts.

False Positive Generation is the deliberate flooding of an IDS with high volumes of traffic engineered to trigger numerous alerts, creating so much noise that analysts cannot distinguish genuine malicious activity from the fake alerts. By overwhelming the IDS alert queue, the attacker effectively hides real intrusion traffic within the flood. This technique exploits analyst alert fatigue and IDS throughput limits rather than bypassing detection logic directly.

An Insertion Attack crafts packets that the IDS accepts and reassembles into a stream, but the target host rejects, causing the IDS to analyze different data than the host actually processes.

Obfuscation involves encoding, encrypting, or fragmenting payload content so the IDS cannot match known malicious signatures, rather than hiding traffic inside a volume of alerts.
