Intrusion Prevention System. A security device that monitors network traffic and actively blocks or drops malicious packets in real time. IPS sits inline with traffic (unlike IDS, which operates passively). It combines signature-based detection with anomaly detection to stop both known and unknown attacks.

Why IPS Matters for Your Cybersecurity Career

IPS is a critical inline defense that cybersecurity teams deploy at network boundaries. Security engineers configure IPS policies and tune rules to balance security with performance. SOC analysts investigate IPS alerts and blocked traffic to identify attack patterns. Understanding the IDS vs. IPS distinction is fundamental for any cybersecurity professional.
