Introduction:

An Intrusion Detection System (IDS) is a security technology designed to monitor network traffic or system activities for signs of malicious or unauthorized behavior. It analyzes inbound and outbound network packets, as well as system logs and events, to identify potential security threats, policy violations, or anomalous activities. IDSs operate by comparing observed activities against known attack signatures or behavioral baselines to detect and alert on suspicious behavior in real-time or near real-time. The primary goal of an IDS is to provide early detection and warning of cybersecurity incidents, enabling organizations to respond promptly to threats and mitigate potential damage to their network infrastructure and data assets.
