Mobile broadband gives us the flexibility to stay connected from anywhere but this ease of access also creates opportunities for cybercriminals to compromise our data. Smartphone tethering, mobile routers and USB dongles should all have their network connections secured. There are a few preventive measures which, when adopted, can minimise the threat posed by mobile broadband.
Why Protect Mobile Broadband
Mobile broadband connections are used on-the-go, making them more vulnerable to cyberattacks. Attackers can easily target mobile routers from the public Wi-Fi hotspots that are often poorly secured, attempting to breach their attendees’ connections to steal data and access any connected devices. Protecting your mobile broadband connection is the first defence needed as hackers can obtain information such as email, passwords, banking account information and other personal details.
Password Protect Mobile Networks
Setting a password on your mobile network is a necessary and effective means of ensuring its protection and security from cybercriminals. Never leave your mobile broadband network without a password and be sure to set strong passwords which will be difficult to guess. Cybercriminals can easily guess simple passwords such as ‘password123’. Effective passwords combine upper and lower case letters, numbers and special characters.
Enable the Highest Level of Encryption
Always confirm that your mobile broadband device employs the most robust encryption standard (WPA2 or WPA3). While encryption does not protect the network alone, it makes it nearly impossible for hackers to read or steal information (data) from it.
Keep Your Device Software Updated
New features aren’t the only focus of software updates. Updates are necessary to incorporate additional security patches that protect devices from potential vulnerabilities. Regular updates to your mobile router, smartphone or hotspot firmware are ideal.
Limit the Number of Connected Devices
The more devices connected to your mobile broadband network, the larger the potential attack surface. Disconnect devices you’re not using and avoid sharing your connection widely. Fewer connections make it easier to monitor activity and spot anything unusual.
Turn Off Your Hotspot When Not in Use
Leaving your hotspot on unnecessarily increases the chance of unauthorized access. Turning it off when you’re not actively using it reduces exposure and conserves battery life at the same time.
Use a Virtual Private Network (VPN)
A VPN encrypts your internet traffic and hides your online activity from potential attackers. This is especially useful when using mobile broadband in public or crowded areas. A reputable VPN adds a strong extra layer of privacy and security.
Avoid Suspicious Websites and Downloads
Even with a secure connection, unsafe online behavior can expose you to risks. Avoid clicking on suspicious links, downloading files from unknown sources, or visiting untrusted websites, as these can introduce malware that compromises your connection.
Enable Firewall and Security Features
Many mobile routers and devices include built-in firewall or security options. Enabling these features helps block unauthorised access attempts and suspicious traffic before it reaches your devices.
Monitor Your Network Activity
Regularly checking which devices are connected to your mobile broadband network can help you spot intruders early. If you see unfamiliar devices, change your password immediately and review your security settings.
