What is intrusion detection/prevention systems?

Intrusion detection/prevention systems (IDPS) are security tools designed to monitor network or system activities for malicious behavior or policy violations. An intrusion detection system (IDS) typically logs detected events and alerts security personnel. An intrusion prevention system (IPS) attempts to automatically block or prevent detected intrusions. These systems analyze network traffic, system logs, and file integrity to identify suspicious patterns and known attack signatures. They are commonly used to protect networks and systems from unauthorized access, malware, and other security threats. They may operate based on signatures, anomalies, or behavior analysis.
