Network security is an organization’s strategy that enables guaranteeing
the security of its assets including all network traffic. It includes both
software and hardware technologies. Access to the network is managed
by effective network security, which targets a wide range of threats and
then arrests them from spreading or entering in the network. Network
security is an integration of multiple layers of defenses in the network
and at the network. Policies and controls are implemented by each
network security layer. Access to networks is gained by authorized users,
whereas, malicious actors are indeed blocked from executing threats
and exploits.
