Essential IoT insights from Q2 20


In this Tech Quarterly

The Internet of Things (IoT) promises to connect many of the devices of daily life and has proven invaluable in the current coronavirus (COVID-19) crisis. Security is a perennial topic, though, and rightly so. As inexperienced work-from-home staff risk attaching vulnerable devices to corporate networks, security experts warn that 98 per cent of IoT data traffic is unencrypted.

Essential IoT insights from Q2 20

26/04/2020 |


1. IoT security shortcomings threaten data privacy and integrity

The current state of IoT security is “scary”, says Mike Nelson, VP of IoT security at PKI provider DigiCert, with 98 per cent of IoT data traffic being unencrypted. The three most common IoT vulnerabilities are lack of proper authentication, lack of data protection (98 per cent unencrypted, remember?) and lapses in data integrity (making sure those often-unencrypted data packets haven’t been altered in transmission).

2. Rumours spread that 5G causes or exacerbates COVID-19 infection

Disturbing news for the reliability of IoT devices that help keep emergency services, healthcare providers, businesses and ordinary people connected: nutjobs are blaming them for causing COVID-19 infections. The baseless rumour has high-profile proponents such as actor Woody Harrelson, who is most famous for playing an idiot.

3. Researchers develop IoT opt-out app

Researchers at Carnegie Mellon University have developed an IoT opt-out app. The IoT Assistant app (for iOS and Android) will, they claim, inform you of internet-connected devices around you and tell you what type of information those devices are collecting. The idea is to allow users to control access to their data and to allow owners of those internet-connected smart devices to comply with privacy regulations such as the GDPR and CCPA.

4. IoT tech proving important in the COVID-19 fight

The journal Nature has identified the IoT as an enabler of essential research, saying “the proliferation of the IoT (e.g. devices and instruments) in hospitals and clinics facilitates the establishment of a highly interconnected digital ecosystem, enabling real-time data collection at scale, which could then be used by AI and deep learning systems to understand healthcare trends, model risk associations and predict outcomes.”

5. IoT has a role to play in increasing security for insurers

Insurance market Lloyd’s sees great potential in using IoT devices to monitor and report information back to insurance organisations, whether it’s monitoring a house for water damage or gathering data at every step of the supply chain to better assess risk. Better accuracy, reduced costs and less fraud are seen as potential benefits.

6. Prognosis for IoT in healthcare is good

Applications in healthcare will become a greater priority for IoT developers in the wake of the COVID-19 pandemic. That’s the conclusion of Achim Granzen, principal analyst at market research firm Forrester. The ad hoc applications coming into play now will, when there is time for greater insight and analysis, form the basis for future development.

7. That sounds terrible

Sonos, the manufacturer of premium smart speakers, illustrated a problem that will likely face many IoT companies as products approach end of life. Sonos declared no further software updates for older hardware and, if users added new Sonos hardware to their existing networks, those devices would also not get updates if older speakers were attached to the same network. It then offered users a 30 per cent discount to upgrade to new hardware that bricked the old hardware. Much backpedaling followed.

8. Is it time to make IoT harder to use?

With many IoT devices found to be lacking in security, is it now time to consider making changes to improve security? Even if that means making it more difficult to use these devices, which have always been sold on their convenience and ease of use? What level of IoT attacks is acceptable?

9. Low-power chips could mean more powerful IoT devices

Wi-Fi power requirements have generally meant IoT devices need large batteries, frequent charging or a power cable plugged into the wall. Now, a new ultra-low-power Wi-Fi radio developed by electrical engineers at the University of California San Diego could change that. It requires just 0.02 per cent of the power of a typical Wi-Fi chip. New uses and smaller devices await.

10. Home networks come with risks for WFH

Workers new to remote working, pressed into carrying on their duties from home without full planning and preparation, may be putting organisations’ whole networks at risk by using vulnerable IoT devices. This is true whether they’re relying on those devices to work from home, or simply using such devices on their home networks.
