At its heart, network security is cyber security, but with a greater focus on protecting interconnected computer systems and their various endpoints. As such, network security covers a range of measures designed to protect the underlying network infrastructure from unauthorized access, misuse, or theft. This involves creating a secure place for devices, applications, users, and data so that they can operate and exchange information securely. By implementing network security measures, businesses can track and investigate network traffic and respond quickly to potential threats–ensuring that their critical network infrastructure remains safe from malicious attacks.
