What is IPS/IDS?

An Intrusion Prevention System (IPS) and Intrusion Detection System (IDS) are network security tools that monitor network traffic for malicious activity or policy violations. An IDS primarily detects and alerts, while an IPS takes proactive measures to block or prevent identified threats. IPS systems are commonly used to automatically respond to detected threats, such as blocking malicious traffic, resetting connections, or quarantining suspicious files, offering a more active defense compared to the passive monitoring of an IDS. Both systems often rely on signature-based detection, anomaly-based detection, and policy-based detection to identify threats.
