IDS: Intrusion Detection System in Cybersecurity
IDS stands for Intrusion Detection System. An IDS monitors network traffic or system activity for signs of malicious behavior and policy violations. It generates alerts when it detects known attack signatures or anomalous patterns but does not block traffic.
How IDS Is Used in Cybersecurity
SOC analysts review IDS alerts to identify potential intrusions and correlate them with other telemetry sources. Security engineers tune IDS signatures to match the organization's threat landscape and reduce noise. Penetration testers test IDS evasion techniques to validate detection coverage.
