Network Security protects your network and data from breaches, intrusions and other threats. This is a vast and overarching term that describes hardware and software solutions as well as processes or rules and configurations relating to network use, accessibility, and overall threat protection.
Network Security involves access control, virus and antivirus software, application security, network analytics, types of network-related security (endpoint, web, wireless), firewalls, VPN encryption, and more.
The basic principle of network security is protecting huge stored data and networks in layers that ensure the bedding of rules and regulations that have to be acknowledged before performing any activity on the data.
These levels are:
Physical Network Security
Technical Network Security
Administrative Network Security
A computer network provides communication and enables the sharing of information to multiple users within a network. Network security technologies work within several layers to protect your network as a whole against any potential threats.
Network security is defined as the activity created to protect the integrity of your network and data.
An intrusion detection system (IDS) monitors network traffic in order to spot potentially harmful transactions and promptly notifies users when one is detected.
