What is Network Security Management?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Network security management is the discipline of overseeing, controlling, and continuously improving the policies, tools, and processes that protect an organization’s network infrastructure from unauthorized access, misuse, and attack. It encompasses everything from firewall management and access control to threat detection, incident response, and compliance enforcement.<\/span>\u00a0<\/span><\/p>

At its core, a network security management system brings together people,\u00a0process, and technology to give security teams a unified view of their environment.\u00a0NSM provides the operational framework that ties them together\u00a0to enforce consistent policy, detect anomalies, and respond to network security incidents with speed and confidence.<\/span>\u00a0<\/span><\/p>

The term is sometimes used interchangeably with network security monitoring, but these are distinct concepts. Management addresses the governance and control layer; monitoring addresses visibility and detection. Both are essential, and effective network security management incorporates monitoring as a foundational capability.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t
