The Intrusion Detection System (IDS) is a new generation of security defense technology developed over the past decade. It collects and analyzes information from several key points in a computer network or system, whether there are violations of security policies and signs of attacks. This is a dynamic security technology that detects, records, alerts, and responses. It not only detects external intrusions, but also monitors unauthorized activities of internal users. IDS technology faces three m
