Whether you work from home or in a large office, the way your computer or laptop connects to the internet plays a crucial role in protecting your data.
Every device needs to connect via a router, and in larger organisations, this may also involve a managed switch. The configuration of this equipment is critical. If it’s set up incorrectly, it can leave significant vulnerabilities, allowing unauthorised access to your network and potentially exposing sensitive data.
Why Router Security Matters
Think of router security like securing your home. Every home has external doors and windows, you need access, but you don’t want strangers simply walking in. You lock your doors and windows and give keys only to trusted people.
A router works in much the same way. It allows you to access the internet, but it must also protect your network from outside intrusion. Routers have “ports” that allow specific types of traffic to pass through: these can be compared to windows in a house. If unnecessary ports are left open, it’s like leaving your windows unlocked, making it easier for someone to get in or take data out.
Key Security Practices
If your organisation aims to achieve Cyber Essentials or Cyber Essentials Plus (CE+) accreditation, network security is one of the most important areas to address.
Best practices include:
Changing router administrator credentials regularly
Disabling unused ports
Separating guest and office networks
Using VLANs to segment traffic
Choosing the Right Equipment
The equipment you choose to manage your network is just as important as the settings you apply. High-quality routers or gateways, such as those from Ubiquiti UniFi, combined with managed switches, provide a stronger security foundation.
While quality equipment can be more expensive upfront, it’s a one-off investment that simplifies securing your network and safeguarding your data.
Don’t Overlook Wi-Fi Security
Wi-Fi is part of your network and is one of the most common access points for cyber threats. Many devices, including mobile phones, laptops, TVs, and smart home technology, connect via Wi-Fi.
To improve security:
Restrict access for untrusted devices
Use strong, unique passwords
Enable network encryption (WPA3, where possible)
By combining robust equipment, correct configuration, and secure Wi-Fi practices, you can significantly reduce your organisation’s exposure to cyber threats.
