How to secure the Computer Network?

Introduction

Prior to the extensive usage of data processing technology, an organisation’s information was protected largely through physical and administrative measures. The necessity for automated solutions to secure files and other information kept on computers became apparent with the emergence of the computer. The emergence of distributed systems and the usage of networks and communications facilities for transferring data between a terminal user and a computer, as well as between computers, has had a significant impact on security.

Network Security

Information, as well as the systems and hardware that use, store, and transfer that information, is protected by network security. The study of computer network security is a subset of computer security. It’s still a branch of computer science, but it’s far more wide than computer security. It entails constructing an environment in which a computer network, with all of its numerous resources, may operate. It refers to the procedures used to ensure the confidentiality, integrity, and availability of data or resources.
