What is Intrusion Detection System?

An Intrusion Detection System (IDS) is a security system that monitors network or system activities for malicious activity or policy violations. It typically analyzes network traffic, system logs, and audit data to identify suspicious patterns or deviations from normal behavior. When malicious activity or a security policy violation is detected, the IDS can alert system administrators, collect evidence, and take other automated actions to mitigate the threat. IDS solutions are frequently deployed to enhance the cybersecurity posture of IT infrastructure.
