True, An intrusion detection system (IDS) captures traffic and compares the intercepted traffic to known good or bad behavior.
A hardware or software program that monitors a network for malicious activity or policy breaches is known as an intrusion detection system (IDS). A security information and event management system is often used to report or gather any malicious activity or violation. Some intrusion detection systems can respond to detected intrusions immediately. These are known as intrusion prevention systems (IPS). There are many different types of intrusion detection systems, ranging from antivirus software to tiered monitoring systems that monitor an entire network's traffic. The following are the most prevalent classifications:
NIDS: A system that analyzes incoming network traffic.
HIDS (host-based intrusion detection systems): A system that monitors critical operating system files.
