A Network Security Monitor (NSM) is a system that is designed to continuously monitor an organization's network traffic for signs of cyberattacks, intrusions, or other security threats. It collects and analyses data from various sources, such as firewalls, intrusion detection and prevention systems, and network devices, to detect and respond to security incidents. The NSM system typically consists of several components, including sensors, collectors, and analysis tools. https://cyberdefenderpros.com/cyber_security_threats_2022
