A network is a group of computers and other devices that are all connected to each other. This allows businesses to share sensitive data, resources, and important information. Because so many organisations rely on it to function and communicate efficiently, network security is critical and should be a central consideration to all digital applications. Here we look at why network security is one of the most effective tools a business can have, what you can do to protect your online activity and the dangers of ignoring potential cyber threats.

Why is network security critical for your business?

Network security is vital to protect a business’s sensitive data. Without it, confidential information is more accessible to hackers. This breach can have a huge financial impact on a business that not only results in lost revenue, but also damages its hard-earned reputation. Organisations therefore need to secure their data, systems, and apps to ensure their network is reliable, and capable of preventing unauthorised access and cyberattacks.

How can a business implement network security?

As a network grows in size and complexity, its vulnerability increases. Unfortunately, there isn’t one single process that can prevent hackers from gaining unauthorised access, so a multi-layered approach is the best option. This involves administering several processes to act as a gatekeeper and stop cyber threats from entering the network, then protect it from within. These include:

Access Control

Network security is critical to a business’s functionality and begins by limiting the access that users have to certain facilities. Depending on their job function, an individual might have access to data, files and emails that enable them to perform their role, but they may not be able to install specific software or have access to other people’s accounts. By restricting the actions of a user, you can reduce the risk of online threats and the potential damage they cause. Access control can be reinforced by asking employees to confirm their identity and validate their admission to network resources. This can be done by administering a password or login, which will determine what their privileges are.

Implement a Firewall

A firewall is a tool that monitors the traffic entering or leaving a network and aims to block any users that appear suspicious. Firewalls can be hardware or software based and have different features depending on their type. For example, a firewall in simple form will filter web traffic based on its source, whereas a more advanced option will have extra levels of protection and control. As well as being installed at the edge of a network, firewalls can be used internally to break it down into smaller subnetworks. This has the benefit of denying hackers access to the whole network if the security of one part is compromised and comes under threat.

Virtual private network (VPN)

A VPN enables an employee to work outside their office and access corporate networks securely. It does this by protecting their identity and masking their location, regardless of whether they’re logging on at home, or using a public Wi-Fi connection. This encrypted connection prevents hackers from gaining unauthorised access and ensures that any sensitive data is transmitted safely. Because smartphones and tablets can also benefit from communicating through a VPN, this method is a useful security tool for corporations who have employees who work remotely and require additional network security.
