What is IDS in cyber security?

A system that monitors network traffic for suspicious activity.

An Intrusion Detection System (IDS) is a security solution that monitors network traffic and systems for suspicious activity and potential threats. It can detect a wide range of attacks, including unauthorized access, malware, and policy violations. IDSs can be classified into two types: network-based (NIDS) and host-based (HIDS). By alerting administrators to potential threats, an IDS helps organizations respond to incidents quickly and mitigate potential damage.
