Network Security vs Cyber Security: What’s the Difference?

In the current digital atmosphere, it is very important to understand the difference between network security vs cybersecurity for the proper protection of sensitive data. Though these are often used as identical terms to each other, they stress different aspects of security. Network security is basically concerned with the protection of the network infrastructure, which includes devices and connections, from unauthorized access and other forms of threats. Cybersecurity, on the other hand, is a broader scope that aims to protect all digital assets, including networks, devices, and data, from a wide range of cyber threats.

Network security and cybersecurity are almost similar concepts, with different strategies and practices. However, at a basic level, differences arise from the scope of the approach and the challenges being addressed. Knowing this would help you develop much more effective security strategies that protect all aspects of your digital environment.

What is Network Security?

Network security is defined as the set of precautions and practices used to protect a computer network against a wide range of cyber threats to ensure confidentiality, integrity, and availability of data and network resources. This entails hardware and software tools that are specifically designed to stop unauthorized access as well as to protect the infrastructure and devices connected to a network from outside threats. This situation exists for any organization that deals with any kind of classified data because it ensures that this data is kept safe from the rest and is still available to those who are allowed to see it.

A network is a grouping of interconnected devices such as computers, servers, and many wireless networks, which are all possible targets of cyber attacks. Network security protects those devices by establishing methods to prevent unauthorized access, defend against attacks, and keep data safe whenever it’s transmitted or accessed. It allows authorized users access to data and services and keeps malicious users away from the network and its resources.

Let’s use an example to understand network security better. Assume you have begun an online transaction. Network security helps with the protection of the online banking system via the methods indicated below:

• A strong Firewall examines all incoming and outgoing traffic on the bank’s network. It safeguards against outside dangers and prevents unauthorized access.
• Intrusion Prevention Systems (IPS) prevent and eliminate the threat at the time of any suspicious activity.
• A Virtual Private Network (VPN) ensures that private financial information is kept private while being transmitted by ensuring encrypted communication between you and the bank’s servers.

Now that we understand what network security is, let’s explore the key advantages it offers for safeguarding organizational infrastructure.

Advantages of Network Security

Network security is important for every business to protect its data and infrastructure because it offers many important benefits:
