Wi-Fi and internet connections
Your internet connection is a way for you to interact with the outside world – but it also provides a channel into your computer. If it isn't secure someone could use it to steal your personal or financial information for malicious purposes.
Use this guidance to learn how to secure your internet connection and home network.
Remember: If you don’t take steps to protect your internet connection and network, they could be used illegally and without your knowledge.
Protect your internet connection
There are a number of easy things you can do to make your internet connection and network more secure. Computer security professionals refer to these steps as ‘hardening’ measures and they do just that – they make your software, your devices, your network and the connections between them harder to access and more resilient to attack.
If you use a modem or router to access the internet
- Change the default administrator (admin) password for the device. The default passwords for these devices are often publicly available online. Make sure you change the password the very first time you use the device. Find out how to set and use strong passwords.
- Ensure remote management is disabled. Remote management on your modem or router can allow you to make changes to your internet connection – including passwords – by logging into your device via the internet . By disabling this function, you are protected from unauthorised people remotely accessing your router and tampering with it.
If you have a home Wi-Fi network
Because wireless networks do not require a wire between a computer and the internet connection, it is possible for anyone within range to intercept the signal if it is unprotected. Find out how to secure your wireless network.
