Intrusion Prevention System (IPS)

A network security tool that monitors traffic and actively blocks or drops malicious packets in real time.

What is Intrusion Prevention System (IPS)?

IPS builds on IDS capabilities by adding active response, dropping suspicious connections or resetting sessions when an attack is detected. It is typically deployed inline, meaning all traffic passes through it, which requires careful tuning to avoid blocking legitimate traffic.

Understanding this concept is crucial for maintaining a robust security posture. In the context of modern cyber threats, intrusion prevention system (ips) represents a significant area of focus for security professionals and organizations alike.
