What is Network Security? Simplified Definition

First of all, what is a network?

The network we refer to here is the computer network, which has so many definitions from too many sources either on the internet or elsewhere. Naturally put, a network is the inter-connection of cables and other communications media, connectivity equipment such as switches and routers, electronic devices such as computers, printers, scanners, plotters, etc., for the purpose of sharing data and resources.

Whoa! Now, that doesn't sound straightforward at all, does it? Alright, let's give it a second try...

A Network is the inter-connection of communications media, connectivity equipment, and electronic devices for the purpose of sharing data and resources.

Now, that wasn't too hard, was it? And here's the second question...

What is Security?

This one is easy, as the word security means protection or safekeeping, protection or well-being.

So Naturally put, Network Security refers to any undertaking designed to protect the network.

Why do we have to protect or "Secure" the network?

We need to protect the network because there are constant threats against the "resources" we share in the network. These could be considerable facts or data about our employees and clients, or more importantly about our products or businesses. Most of these threats come in the form of:

* Viruses, worms, and Trojan horses
* Spyware and adware
* Zero-day attacks, also called zero-hour attacks
* Hacker attacks
* Denial of service attacks
* Data interception and theft
* Identity theft

In order for us to fully understand what "Network Security Solution" is all about, we must also understand how Network Security works. Because there are a variety of threats, there is no single solution. We need complicated layers of security, so that if one fails, the attacker would have to deal with the next layer.

Network Security Systems are ordinarily composed of many components of both software and hardware which are designed to work together to heighten security and minimize maintenance. The software must be relentlessly updated to preclude from new threats.

These components include:
* Anti-virus and anti-spyware
* Firewall, to block unauthorized entrance to your network
* Intrusion prevention systems (Ips), to detect and block attacks
* Virtual private Networks (Vpns), to provide obtain remote access
