The US intelligence chief has acknowledged for the first time that agencies might use a new generation of smart household devices to increase their surveillance capabilities.
As increasing numbers of devices connect to the internet and to one another, the so-called internet of things promises consumers increased convenience – the remotely operated thermostat from Google-owned Nest is a leading example. But as home computing migrates away from the laptop, the tablet and the smartphone, experts warn that the security features on the coming wave of automobiles, dishwashers and alarm systems lag far behind.
In an appearance at a Washington thinktank last month, the director of the National Security Agency, Adm Michael Rogers, said that it was time to consider making the home devices “more defensible”, but did not address the opportunities that increased numbers and even categories of connected devices provide to his surveillance agency.
However, James Clapper, the US director of national intelligence, was more direct in testimony submitted to the Senate on Tuesday as part of an assessment of threats facing the United States.
