Network Security, Defined and Explained
Network security refers to the technologies, processes, and policies used to defend any network, network traffic, and network-accessible assets from cyberattacks, unauthorized access, and data loss. Every organization, from small businesses to the largest enterprises and service providers, in every industry requires network security to protect critical assets and infrastructure from a rapidly expanding attack surface.
Network security must protect at the many edges of the network and also inside the network, with a layered approach. Vulnerabilities exist everywhere, from devices and data paths to applications and users. Because organizations encounter so many potential threats, there are also hundreds of network security management tools intended to address individual threats or exploits or assist with other mission-critical infrastructure needs, such as continuous compliance. Organizations should prioritize network security solutions that cover the multitude of threats, using a platform approach that prioritizes integration and automation.
