The rush to enable remote work in March 2020 understandably led to some fairly loose interpretations of security policies, but a year and a half later, although ad hoc agreements are being formalized, a threat persists in the form of the Internet Connected Things (IoT) devices seem so harmless that they barely think.

Some, mainly in industrial applications, provide essential data useful for businesses. Others are a little more suspicious. Anyone who suspects the proliferation of IoT devices should just look @InternetOfShit Twitter account and marvel at the range of useless data MAC address devices.

Others are also on the way: the proliferation of 5G networks will see ‘smart city’ projects grow. Even if autonomous machines, first tested in 2005, remain somewhat distant, high-speed, low-latency networks will launch a revolution in edge processing applications – and processing equipment.

Just what is in these devices is a key issue. Digital sovereignty has now reached the top of the diplomatic table with a diverse caste of troubling characters: both former US President Donald Trump and his successor Joe Biden imposed restrictions on Huawei, while French President Emmanuel Macron, increasing his country’s research budget. , stressed the importance of the development of its technology by the EU. Concern also exists among friends: Britain has raised the alarm about the sale of Arm Holdings to US chip giant Nvidia.

Beyond the possibility of slipping home phone firmware into corporate networks, a more immediate concern is consumer-level devices, where the use of cheap components, driven by thin boundaries like blades, means that devices often do not are secure or left unpacked as the support disappears along with the manufacturer.

Research recently published by Palo Alto Networks found that a wide range of curious computers were returning to work alongside staff: 78% of respondents who have IoT devices connected to their network reported an increase in non-business IoT devices in corporate networks in recent years. vit.

The report said the most impossible equipment, from routines to automated pet foods, was coming in. He also found that 78% of IT decision makers reported an increase in IoT security incidents.

IoT devices are often seen as having low computing power, but this is not necessarily true nor is the problem: poorly secured or unsupported devices create a vector for attack.

“The bad guys are using ML and bots. They are using the same technologies as organizations are using to stop them. “All these guys are trying to do is use some form of organization,” said Palo Alto Networks Ireland Country Manager Paul Donegan.

Of course, the threat is more severe with remote workers and requires education on what should and should not be connected, as well as router tactics such as network segmentation, he said.

“It simply does not make sense [but] back to education. “For example, I have my work laptop and other work equipment connected separately from everything else,” said Donegan.

However, IoT devices are also finding their way into offices. Just think of the proliferation of smart TVs or the existence, for some reason, of connected lamps. Any other IT purchases should be made on the basis of a business case, so perhaps replacing them with ones that do not contain as much silicon would be a great idea.
