Network security is concerned with the security of computers or devices that are part of a network infrastructure.
Network security can be defined as a broad term that includes many technologies, devices and processes. In the simplest terms, network security is a set of rules and configurations designed to protect the integrity, confidentiality, and accessibility of computer networks and data using software and hardware technologies. Every organization, regardless of size, industry, infrastructure or structure needs a level of network security solution to protect it from the ever-evolving cyber threat landscape in today's wild.
There are many avenues to consider when addressing network security across an organization. Attacks can occur at any path in the network security layer model, so hardware, software, and network security policies must be designed to address each area. Network security usually consists of three distinct controls: physical, technical and administrative.
