What is Network Security Monitoring?

Network Security Monitoring (NSM) is the process of collecting and analyzing network traffic data to detect suspicious or malicious activity. It commonly involves deploying sensors to capture network packets, logs, and alerts, which are then analyzed using various techniques, including signature-based detection, anomaly detection, and behavioral analysis. NSM helps organizations identify and respond to security threats in real-time, improve their security posture, and comply with regulatory requirements.
