What is NSM?

NSM typically refers to Network Security Monitoring. It involves the systematic collection and analysis of network traffic data to detect and respond to security threats. NSM commonly uses tools like intrusion detection systems (IDS), intrusion prevention systems (IPS), and security information and event management (SIEM) systems to identify malicious activity, policy violations, and other security-related events. It's used for threat detection, incident response, and security analysis.
