What Is Network Security & Why Is It Important

Network security professional is at work

Virtually everything we do requires a network connection, from ordering takeout to joining a Zoom call. The networks we use each day must be kept safe and secure to ensure critical information doesn’t fall into the wrong hands. This is the basis of network security, a critical part of information technology (IT).

What Is Network Security?

Network security involves the processes used to protect computer networks against unauthorized access or misuse. For example, network security prevents cybercriminals from stealing proprietary data stored on a network. It also ensures authorized network users have easy and secure access to all of their critical data and information.

There are various components used to secure a network, including firewalls, VPNs, anti-virus software and more. These components mixed with quality network security practices prevent networks from succumbing to malware, spyware, botnets and other intrusions, whether through intentional means or by accident.

Why Is Network Security So Important?

Network security is important for a number of reasons. For example, network security helps organizations prevent costly data breaches that can result in millions of lost revenue. In fact, the average cost of a serious data breach is $4.24 million, according to IBM.

Network security also helps prevent the dangerous sharing of consumer data such as social security numbers, private health information and financial information. Cybercriminals can use this information to assume someone else’s identity which has many negative consequences.
