Definition

Intrusion detection is the process of monitoring network traffic and system activities for malicious activities or policy violations. It involves the use of specialized software or hardware to detect and respond to unauthorized access attempts, malware infections, and other security incidents.

History/Origins

The concept of intrusion detection dates back to the 1980s when researchers began exploring ways to detect unauthorized access to computer systems. The first intrusion detection systems focused on signature-based detection, where known patterns of attacks were matched against network traffic. Over the years, intrusion detection technology has evolved to incorporate anomaly detection, machine learning, and behavioral analysis to enhance detection capabilities.
