Intrusion Detection System

An Intrusion Detection System (IDS) is a security tool designed to identify the presence of intruders or detect security breaches within a network or system. Its primary function is to alert administrators to potential threats, security violations, or unauthorized activities. In addition to issuing notifications, an IDS may facilitate detailed logging of events for forensic analysis and investigation. Depending on its configuration, an IDS may also initiate responses such as terminating sessions or blocking IP addresses associated with suspicious activity. Unlike proactive security measures that aim to prevent intrusions, an IDS operates in a more reactive manner by detecting compromises after they have already occurred, making it a valuable component of comprehensive cybersecurity strategies.
