The 4 Different Types of Network Security and Why You Need Them--1

Network security has become a very important topic these days, since the number of cyber attacks have increased greatly over the past few years. The global cyber crime costs are expected to rise to around $2.1 trillion by the year 2019, which just goes on to show how important it is for you to pay attention to network security.

There are 4 main types of network security that you can take advantage of and we are also going to cover why you need them.


1. Network Access Control (NAC)

The Network Access Control or NAC controls which people can access your network and which ones can’t. It allows you to identify different users and devices, and find out if unauthorized personnel are trying to gain access to the network. You can therefore, enforce different security policies in order to block devices and control what can happen in your network.

You can also set up behavioral analytic tools, which helps you identify abnormal behavior on your network, so that you get notified when someone is acting abnormally on your network.


2.    Application security

You can also take advantage of application security, which is designed to offer complete protection to your applications. It is important, since it ensures that apps with flaws in them aren’t targeted and taken advantage of by hackers. It basically secures your network from the threat of your applications getting hacked, which is why it is definitely an essential network security tool you must have.


3.    Antivirus and Antimalware Software

You must definitely use antivirus and antimalware software in order to protect your network from spyware, phishing, Trojans, and viruses. Malware is like a disease for your network, and will not only stay within your network, but will spring attacks, and cause your systems to malfunction.

Antivirus and antimalware software allow you to easily detect malware and other virus threats, since they will be continuously scanning the network searching for malware that is hiding.

The big problem here is that wireless networks aren’t very secure, and can be easily attacked by hackers, which is your wireless security needs to be top notch.


The Importance of Network Security

Organizations and businesses today, need to understand the importance of network security. It doesn’t matter whether it is a government organization, a startup, small-business, or a multi-national, network security should hold the same level of important for them. A breach in the network security can result in all types of irreparable harm, which is why organizations need to be educated about the importance of network security, why should secure it.

Organizations need to update their systems regular, especially because hackers are discovering new flaws in security networks and coming out with new methods to gain access to unauthorized networks.

1.    Deter

Educate people and discourage them from breaking into networks for malicious or illegal reasons.

3.    Detect

Learn to recognize security breaches, and keep a record of everyone that has access to the network.


4.    Correct

♦    Modification

A modification attack is based on tampering with resources, and will generally change information that is communicated between parties. It could be sending the wrong information to a party in order to cause miscommunication.


♦    Fabrication
