What is the primary purpose of an intrusion detection system (IDS)?

The primary purpose of an intrusion detection system (IDS) is to monitor network traffic for suspicious activity. An IDS analyzes incoming and outgoing traffic to identify potential security threats or unauthorized access attempts by comparing the traffic against known attack patterns or anomalies. This enables organizations to detect and respond to intrusions in real-time, helping to mitigate potential damage and enhance overall network security.

This function is crucial in maintaining cybersecurity, as it allows for immediate alerts when irregularities are observed, ensuring that appropriate measures can be taken to address threats swiftly. Unlike systems focused solely on prevention or access management, an IDS is specifically designed to identify and report potential security breaches.
