What Is Network Security? Fast Facts About Keeping Your Network Safe

Experts estimate global cybersecurity to become a $137 billion market this 2021. The rise in cloud computing use and Bring Your Own Device (BYOD) policies are the top drivers of this growth.

$137 billion may seem a lot, but that’s only a tiny portion of what cybercrime damage can inflict. Experts believe that this 2021, cybercrimes will cause at least $6 trillion in damages.

All that proves how network security, a subset of cybersecurity, is now a must for everyone.

What is network security, though, and what exactly does it protect? Why is it such an important aspect of cybersecurity?

We’ll answer all these questions (and more) below, so be sure to read on!

What Is Network Security?

Network security protects data, software, and hardware within a computer network. It uses technical configurations aimed to protect network integrity, confidentiality, and accessibility. 

One of the chief goals of network security is to bar the potential misuse and hacking of data. It also aims to prevent unauthorized access to any part of a network.

The use of authentication protocols and antivirus programs are examples of network security. Authentication includes assigning authorized users with log-in credentials to a network. Antivirus programs protect data sent over a network, such as from one PC to another.

Why Is Securing Your Network So Important?

A recent study found that about 15% of cyber threat actors are non-malicious insiders. Many of these “insiders” are employees who fall victim to cybercrimes. A lack of security training makes them vulnerable to, say, clicking on a phishing email.

However, some employees also carry out intentional cybercrimes, such as unauthorized data access. In some cases, they may use data they have access to for illegal purposes. The worst cases involve insiders who carry out crimes for financial gain.

Network security helps reduce the risk of both insider and outsider cyber crimes. For example, it uses authorization to assign access levels. In this way, users can only access data based on their privileges.

Network security also blocks confidential data from leaving a network. It encrypts data to safely pass it from within the network or to an external location. It also shields a network from external attacks, such as malware.

Is Network Cyber Security the Same as Cloud Security?


Network security’s primary focus is the data, software, and hardware within a network. Cloud security protects internet-connected networks, servers, software, hardware, and the data they contain. This is why many experts regard network security as a subset of cloud security.

Are Their Laws on Network Security in the US?

In 2020, 38 states, plus D.C., either considered or passed over 280 cybersecurity bills. Some of these resolutions mandate businesses to put cybersecurity policies in place. Non-adherence can lead to businesses getting slapped with class-action lawsuits.

Some states have also placed stricter penalties for cybercriminals. For example, some cybercrimes that used to be misdemeanors are now felonies. Punishments include jail time of at least one to 20 years or more.

Network Security Is Key to a Comprehensive Cybersecurity Plan

There you have it, the ultimate guide that answers the question, “what is network security?” Now that you know what it is and what it’s for, it’s best you start implementing network security protocols. The sooner you do, the sooner you can protect your networks from insider and outsider threats.
