Computer Weekly December 2018:
The proliferation of poorly secured network-connected devices has prompted the UK government to publish new best practice guidelines. Do these go far enough?
Wireless functionality has improved workplace efficiency and organisations are no longer restricted by cabling access. Unfortunately, many of these devices are poorly secured and rarely have their firmware updated.
“The proliferation of IoT devices with poor security posture has increased the attack surface for threat actors dramatically,” says John Sheehy, vice-president of ioActive. “Compromised devices can be used by threat actors for anything from listening in on conversations and harvesting sensitive data, to cryptomining and jumping to traditional IT systems.”
Incidents where hackers have been able to exploit poor device security to obtain sensitive data have resulted in significant reputational damage, as happened to vTech in 2016. Such incidents could now – under the Data Protection Act 2018 – see companies fined.
As such attacks have become more frequent, the UK government has decided to step in. Earlier this year, the Department for Digital, Culture, Media and Sport (DCMS) published the Secure by Design report and later the Code of Practice for Consumer IoT Security – a guidance document advising on the best practices for securing IoT devices.
These guidelines are currently voluntary and are broken down into thirteen steps, as follows:
- No default passwords – all IoT device passwords should be unique and not resettable to any universal factory default value.
- Implement a vulnerability disclosure policy – all companies that provide internet-connected devices should provide a public point of contact as part of a vulnerability disclosure policy in order that security researchers and others are able to report issues. Disclosed vulnerabilities should be acted on in a timely manner.

For all of the challenges that come with this, organisations can nonetheless benefit from following such guidelines. In a survey by Bain and Co, it was discovered that executives would be prepared to spend 22% more on IoT devices that were proven to be secure.
This increase in income could be used by manufacturers to offset the costs associated with following these best practice guidelines. Furthermore, reputation of the company would be protected by having secured their devices appropriately.
