What is the process called when an attacker confuses an intrusion detection system by forcing it to read invalid packets?

• A. Insertion Attack
• B. Evasion
• C. Obfuscating
• D. False Positive Generation

Answer: (A)

This question is about how an attacker can disrupt an intrusion detection system by introducing ill-formed or crafted traffic into the stream, so the IDS processes packets that it shouldn’t or misinterprets the flow. When invalid packets are injected, the IDS can become confused, leading to misdetections or false alarms. This tactic is known as an insertion attack, because it adds packets into the data stream to manipulate how the IDS observes and analyzes traffic. It’s different from evasion, which generally means slipping past detection with traffic that is carefully crafted to look legitimate; obfuscating focuses on hiding the actual payload; and false positive generation centers on causing alerts that aren’t warranted rather than manipulating the packet flow itself.
