Network security is a broad term that covers a multitude of technologies, devices, and processes. In its simplest term, it is a set of rules and configurations designed to protect the integrity, confidentiality, and accessibility of computer networks and data using both software and hardware technologies.
Every organization, regardless of size, industry, or infrastructure, requires a degree of network security solutions in place to protect it from the ever-growing landscape of cyber threats in the wild today.

Network security typically consists of three different controls: physical, technical, and administrative. Here is a brief description of the different types of network security and how each control works.
Physical Network Security
Physical security controls are designed to prevent unauthorized personnel from gaining physical access to network components such as routers, cabling cupboards, and so on. Controlled access, such as locks, biometric authentication and other devices, is essential in any organization.
Technical Network Security
Technical security controls protect data that is stored on the network or which is in transit across, into or out of the network. Protection is twofold; it needs to protect data and systems from unauthorized personnel, and it also needs to protect against malicious activities from employees.
Administrative Network Security
Administrative security controls consist of security policies and processes that control user behavior, including how users are authenticated, their level of access, and also how IT staff members implement changes to the infrastructure.
