What is Network Security?
Network security refers to policies, practices, and technologies that prevent attacks on an organisation’s networks and network accessible resources.
Network security definition
The network is a major area of risk exposure. It usually defines the actual security perimeter itself. As a result, attackers frequently target the network as a first step in penetrating other IT assets. Network security is all about defending the network, as well as connected resources, from threats. Network security utilises both physical and software countermeasures to protect network infrastructure from unauthorised access, malfunction, misuse, modification, and destruction.
Why network security?
Network security is essential for overall cybersecurity because the network is a significant line of defense against external attack. Given that virtually all data and applications are connected to the network, robust network security protects against data breaches. Yet, as network use expands and incorporates wireless capabilities and multiple device types, network security grows more complex. Network security needs to keep up with these kinds of changes to keep the organisation secure.
