In my previous article, I have talked about all that you need to know about networks. In this article, I want to talk about some of the network basics that you need to know as a network security expert. Follow me as we are going to look at that in this article.

Major Networking Basics

A network is simply a way for two or more devices to communicate and share resources.

On a physical level, it consists of all devices that you want to connect and the resources that you are going to use to connect them together.

Please note that individual devices can be connected using cables as a medium of connection. They can also be connected together through the use of wireless devices.

In order to connect multiple devices together, each device must be connected together using a device called a hub or a switch as a tool for such connection.

These hubs/switches must be connected together. In a larger network, each of the subnetworks is connected together by using a router as a mode of connection.

Basic network structures …

Connection points must exist between your network and the outside world.

Also, a barrier will be set up between your network and the internet. This can be done with the use of a device called a firewall.

Above all, the major purpose of a network is to have communication between a machine and other devices within and outside the network.

It should be established here that every path through which networks can communicate can also be an avenue to attack such networks.

The first line of defense that you have in order to prevent your network from being attacked or hijacked is to understand how a network works.

Also, network interface cards, routers, switches, and hubs are the fundamental physical pieces of a network.

The way they are connected and the fact that they are used for communication is what is known as network architecture.
