Why home Wi-Fi poses a business risk – The Australian Financial Review

“The key vulnerability in the home network is the Wi-Fi router. A lot of people are still using the routers from when they first signed up for the internet. They could be 10 years old. And you can bet that the firmware on those routers isn’t being updated,” he said.

“People have bought a $50 router, and it’s the only thing standing between their home network and the entire internet.”

Strategic consideration

Insecure Wi-Fi routers make it easier for hackers to compromise computers on the network; they make it possible for hackers to snoop on corporate apps that haven’t been secured with end-to-end encryption; and they can be used in “man-in-the-middle” attacks, where hackers divert traffic to their own computers before forwarding it on to its destination.

“The best way for a corporation to deal with this is to send staff home with a corporate-managed laptop with a 4G or 5G dongle, so (data) never has to go through the home network,” he said.

Tim Dillon, a founder and analyst at Tech Research Asia, said that because of the security and connectivity lessons learnt from the lockdown, 5G is now becoming a strategic consideration for corporations, rather than just a handset consideration.

Mr Dillon said the past few months had been a catalyst for businesses to consider how they approach their security strategies for mobile devices, within which sits 5G.

“The whole connectivity thing has become much more important since COVID,” he told the Financial Review.

“As they deal with a mass migration of employees to working from home, and then a phased return to work, in an environment that is much more digital than it was, they’re asking where does mobility fit within that?

“And what they’ve realised is that connectivity is absolutely critical. Some of it will be dongles, some of it will be fixed broadband, some of it will be fixed wireless, some of it will be tethering to mobiles,” he said.
