network intrusion detection
/ˈnet.wɜːk ɪnˈtruː.ʒən dɪˈtek.ʃən/ IELTSAcademic
noun
The process of watching a computer network for signs of unauthorized access or attack. It helps find suspicious activity early.
- Network intrusion detection caught the attack quickly.
- Our company uses network intrusion detection every day.
- The system flagged unusual traffic last night.
Adinary Nuance
Network intrusion detection is about spotting unwanted activity on a network. It is not the same as network security, which is the wider field of protecting a network. It is also different from prevention tools like a firewall, which try to block attacks before they enter. Intrusion detection watches and alerts; it does not always stop the attack by itself.
