Network security is at the heart of a functional, productive business—regardless of its size or the scope of its services. The network security umbrella is broad and applies to a variety of devices, processes, and technologies. On a basic level, network security is composed of configurations and rules that are implemented into devices and systems on your network. These rules ensure your network’s integrity, privacy, and usefulness, and cover both the hardware and software that make your network run. Security measures can be applied to individual devices or to groups of components with the same level of vulnerability. You can also choose where to place protective measures.
