An Intrusion Detection and Prevention System (IDPS) is a security solution that monitors network traffic and system activities to detect, alert, and prevent cyber threats in real time. It combines the functionalities of an Intrusion Detection System (IDS), which identifies and alerts on suspicious activities, and an Intrusion Prevention System (IPS), which actively blocks or mitigates threats before they cause harm. IDPS solutions use signature-based detection (matching known attack patterns), anomaly-based detection (identifying unusual behavior), and policy-based detection (enforcing security rules). They help protect against malware, denial-of-service (DoS) attacks, unauthorized access, and other cyber threats. Popular IDPS solutions include Cisco Firepower, Palo Alto Networks, Snort, Suricata, and Fortinet FortiGate. Learn more: https://en.wikipedia.org/wiki/IDPS
