Security needs to be put in
place early and needs to be holistic”
Security
As with all information technology, protection of data is vital with the IoT. So far, though, success in this area has not been universal. Mark Begbie recounted a story he heard recently about a traffic light system deployment that had no authentication or encryption. “Someone with a drone and a wireless system flying over them could have turned the lights whatever colour they wanted. That could have ended up like a scene from the Italian Job.”

It is clear, then, that there are some gaping holes in this area. “Security is a huge issue, and something we are working on ourselves. For instance, we are currently funding a research programme involving Napier University and Keysight Technologies looking at platform security and how you test and certify small devices.” He continued: “A lot of the devices on the IoT are going to be low powered and will be moving very small amounts of data. You have to look at the processing power you require, the security you need to protect that and what you can afford.” As well as vulnerability, those
deploying the technology will need to
assess the value of the data to others, Mark added. “If you are using it to monitor the
temperature of your vegetable patch, there would probably be very little impact in a hack. But if it involves critical medical care, clearly that is very different and you have to take appropriate steps to protect your systems.” Dr Ivano Bongiovanni, a fellow at
the Adam Smith Business School at the University of Glasgow, said that the opportunities offered by the Internet of Things have to be set alongside the accompanying risk of deployment. “Sometimes you will be trying to
connect across legacy systems. The security levels enabled by those older systems may not be the same as required for modern connected devices.
“It might actually make more sense
to go for a green field approach, designing from scratch with the required protection built in. “Security needs to be put in place early and needs to be holistic. And it’s worth remembering that human collaboration is one of the most effective ways of achieving information security.”
