What is Network Security and Why Is It Important?

Published: August 4, 2021
 

It used to be that businesses only had to worry about the physical security of their factories, plants or retail stores. But now, they need to worry about the security of their software, hardware, and computer networks. To protect against cyberattacks, other external threats, internal mistakes, damage, and disaster, you need sound network security and trained professionals who are always on guard. If your organization’s internal network isn’t secure, you won’t be able to prevent attacks that come at you through the internet and your whole business could be in trouble.

What Network Security Does

Think of network security as the bodyguard for your company’s internal data. It encompasses the hardware, software, connections, and processes used to keep your computer network safe from cybercriminals who could hack into your network and steal or damage your data. And while much of network security is technical, there’s also some commonsense approaches to it that might surprise you. You can keep your network secure by locking doors to IT areas, servers, and routers. Making sure only authorized personnel have access to your network is a good first step at security.

Installing Network Security Technology

There are also technical measures you can take to protect your network, including the installation of these security features:

  • Firewalls: A firewall monitors and controls your network traffic based on security rules you set. It’s a barrier against intruders who could access your network from the internet.
  • Antivirus Software: Antivirus software works in real time to detect and eliminate viruses that may infiltrate your network. It can also detect spyware, which could be used to collect information.
  • Network Access Control: This is a measure that allows your organization to choose who has access to what information. This ensures that data stays well protected and away from those who could compromise its confidentiality.

How to Start a Career in Network Security

So, who sets up and maintains these security measures for businesses? Computer network support specialists. According to the U.S. Bureau of Labor Statistics, employment of these professionals is expected to grow faster than the average over the next decade. As organizations upgrade their cybersecurity protocol, computer support staff will be in demand to help make these changes.

If you want a career as a computer network specialist, you’ll need to learn how to do the work. Look for a computer networking systems program that will teach you how to run diagnostic tests that can help you detect issues and solve problems. You’ll also need to learn about cloud computing and networks, how to develop applications, how to use administration tools for Windows, and how to prevent cyberattacks.
