Intrusion Prevention System (IPS): An advanced version of IDS that not only detects but also actively blocks and prevents unauthorized access or malicious activities.
Signature-based Detection: A method used by IDS to compare network traffic against known patterns or signatures of known attacks, helping identify and alert about potential threats.
Anomaly-based Detection: A technique used by IDS to establish a baseline of normal behavior within a network and then detect any deviations from that baseline, which may indicate suspicious activities.
