Norton by Symantec surveyed more than 5000 consumers from Australia, the US, UK, Canada and Japan about their fears concerning the "connected world" and the Internet of Things.
The use of mobile apps to control connected devices is most common in Australia, with 63% of respondents using at least one mobile app to manage their finances or control connected devices such as home entertainment systems, fitness trackers, baby monitors, cars, home entry systems, light switches and smart home appliances.
A total of 66% of Australians do not have security software on their smartphones and 33% don't even take the basic precaution of setting a password or PIN, yet 61% said the prospect of their financial and banking information stored on their phone being hacked is upsetting.
"There is a general lack of security awareness amongst consumers when it comes to managing IoT devices from mobile apps. Getting hacked is not something consumers worry about with the devices they use to monitor their children, lock their front doors or manage their entertainment systems," said Norton by Symantec's Pacific region director Mark Gorrie.
"Most of the research into attacks on IoT devices has focused on attacking the device directly, but there is another way these devices are at risk: many IoT devices are controlled by mobile apps and by not protecting these apps, Australians are leaving the door wide open for hackers."
Norton by Symantec's recommendations are the usual ones, including:
• Use a reputable mobile security app
• Download apps from official app stores
• Be mindful of app settings (especially requests to disable settings that protect you from installing unsecure apps)
• Keep device software up-to-date
• Protect devices with strong passwords (at least eight mixed characters)
• Use WPA2 when connecting devices to Wi-Fi networks, or better still use a wired network connection
• Disable device features that you don't use
"The solution is not to panic, nor is it to stop using these devices. Mobile apps and IoT devices aren't going away but there are some simple, best practices Australians can adopt to keep their IoT devices and mobile apps secure," said Gorrie.
