Telstra says its shared Wi-Fi network will be secure

Shared connections should be secure with correct settings, says privacy expert

Telstra CEO David Thodey asserts that public Wi-Fi network will be secure.

Telstra CEO David Thodey asserts that public Wi-Fi network will be secure.

Telstra has stressed that customers should have no security concerns about sharing their broadband connection with other users over Wi-Fi or – conversely – accessing another customer’s shared connections as a hotspot.

The sharing of home and business broadband connections is a key part of a national public Wi-Fi network announced today by Australia’s biggest telco. Telstra home and enterprise broadband users will be able to access 2 million Wi-Fi hotspots around Australia in five years if they agree to share their own connection, according to the plan.

“Security is a really important aspect,” Telstra CEO David Thodey said today.

“We want to make sure you’ve got the bandwidth and your connection is protected, and then we’re making sure that the public access side has the normal Wi-Fi security and ... authentication.”

The modem will be secure and locked down, and the public configuration for hotspots will be the same as existing public hotspots, said Mike Wright, Telstra group managing director of networks.

Telstra customers who opt in to sharing their connection should be able to do so securely if the right settings are ticked, according to Malcolm Crompton, managing partner of consultancy Information Integrity Solutions.

“If people apply the maximum security (MAC address filtering, strong passwords etc.), the risk shouldn’t be too great,” said Crompton, a former Australian privacy commissioner.

“So the question is to what lengths should individuals go and to what lengths will they go in practice (potentially two different things),” he said.

“And the gap between the two, in turn, is likely to depend on the defaults that Telstra puts in place when individuals join or install.”

Telstra plans to make it completely “opt in” for customers to share their connections with other users. Crompton said this is essential from a privacy perspective and in fact probably unavoidable.

“Even if [Telstra] tried, there are likely lots of ways to frustrate any ‘opt out’ or ‘compel’ model,” including by changing Wi-Fi settings or setting up MAC address filters, he said. “But more than that, I think we are reaching the stage in public awareness of privacy online where compulsion would be commercially unacceptable: the backlash too strong.”

US cable company Comcast attracted some controversy in the US when it turned on Wi-Fi sharing by default and required users to opt out.

I find the numbers very hard to believe.

I know Telstra has a large share of the market. This is because they rely on their historical precedence as a telephone provider. They also specifically target a non-technical audience, that doesn't understand just how much of a premium they are paying for using Telstra as an ISP, witness their charging for uploads, and incredibly high excess usage fees.

So we are expected to believe they can activate 2million hotspots, with their own rollout, and voluntary enablement by the same non-technical subscriber base? If these users get anywhere near their quota, they have likely already been slugged with a Telstra excess usage bill, whats the chances of them letting others use their connection no matter how many assurances Telstra utter.
Perhaps they planning on 1.9 million Telstra hotspots and <100k home users, because 2 million out of a population of 25 million staggers belief!



First, your characterisation of Telstra customers being with them only because they are non-technical is both incorrect and offensive. My preference is to deal with the organ grinder and avoid the monkeys, so I give those just reselling what others build wide berth.

You demonstrate your own ignorance by failing to understand the difference between a user ticking a box on a form to opt into this service and having to physically configure their own modem to make use of it. There are mechanisms that allow the complexity of modem configuration to be hidden from end users. Maybe your ISP is still operating in the dark ages and has yet to come across this.

Finally, if you had any clue about this service you would know that guests on your Wi-Fi modem are using their own service and data allowance, not yours. If you are close to your limit, test assured that visitors won't push you over. They are sharing bandwidth and the amount of bandwidth shared can be controlled by the owner, but that is all.
