All About Network Security & its Essentials

What is Network Security?

Network Security is the first line of defense against hackers and other cyber threats. It’s easy to see why Network Security has become so popular, given that cybercrime is expected to cause $6 trillion in global damage by 2021. Most experts define Network Security as policies and procedures to prevent encroachment, modification, misuse, change, destruction, or unauthorized access and reveal data on information systems. Or we can say that the rules and procedures used to mitigate and regulate unauthorized access, misuse, modification, or exclusion of a computer network and its resources are known as Network Security. The entire process necessitates a combination of hardware devices, security software, and user awareness of security procedures and techniques.
