Mobile Broadband

Mobile broadband security

Before you get online, you’ll want to make sure that you’ve taken the correct security measures to ensure that no one can hack into your laptop and start downloading over your new mobile broadband connection.

But what are the risks when using a USB dongle, and what security measures should you take?

The biggest risk

Because a mobile broadband connection is essentially a mobile phone contract, with a SIM card, the biggest risk is that you’ll lose your modem, or it will get stolen, because anyone could simply plug it into their own computer and download as much as they want - all of which will go on your bill at the end of the month.

If you do lose your modem, or if it does get stolen, you need to ring your provider and tell them as soon as possible to make sure that the line is cancelled or suspended - just as you would with your mobile phone.

Local IP connection

Unlike a normal, fixed line broadband connection, mobile broadband users aren’t assigned an internet IP address. Instead, you’ll have a local IP address like you would in an office.

Although you won’t notice any difference when you’re browsing the internet, this actually makes your connection more secure. Just like in an office, your connection sits behind the provider’s firewall, with a local IP address - making it far harder to hack into.

However, this does mean that you won’t be able to connect to your mobile broadband connection remotely from another computer.

Built-in encryption

Because mobile broadband uses the provider’s mobile network where everything is already encrypted, it’s like having a WEP or WPA key built into your connection.

It’s not like wireless

Although it feels like you have a “wireless broadband” connection, no one else could scan for your signal as they would be able to do with wifi. So if you’re using your modem on a train or in a coffee shop you don’t need to worry about other people in the area hacking in.

Mobile broadband routers

However, if you are using a mobile broadband wireless router or a mobile wifi dongle, you’ll have to take the usual wifi precautions - such as setting a secure WEP or WPA key - so that unauthorised users can’t simply scan for your signal and connect to your router.

General security

Anyone accessing the internet needs to ensure that they have a reliable, up-to-date security software such as Norton or McAfee installed on their PC to protect them from viruses, Trojans and hackers.
