Internet-connected appliances have created a smart hub of endless opportunities. But outside this hub, there’s always someone trying to peer inside…
How many smart devices do you have in your house? Most adults in the developed world are fortunate enough to own a smartphone, maybe two because of work. You might also have a laptop at home, but our houses are also becoming increasingly populated with smart speakers, TVs, fridges. You might be wearing a smart watch on your wrist as you read this.
All these internet-enabled devices make up what we call the Internet of Things (IoT). This is a network of devices, whereby sensory devices collect data on how they are used in the context of their surroundings, then send this info to the cloud, which stores and processes it before sending the data to the general devices in the network to make them ‘smarter’, in a cycle known as machine learning.
IoT originates from the Carnegie Mellon University in the early 80s, where students connected a vending machine to the internet to gage its drinks’ temperature from their computer screens. Ever since, smart devices have been on the rise.
Corporate advantages of IoT
In that first instance, the technology enabled individuals to make smarter, more efficient decisions, and its benefits remain much the same today, both in a personal and professional setting. In a business context, IoT is most utilised in the utilities sector through office equipment that are used across all industries, as well as more trade-specific apparatus.
IoT also offers great benefits when used as part of an agile working environment – it can unlock more data about their internal systems and thus drive greater performance and revenue. Furthermore, it allows for the automation of certain tasks, which saves time and ultimately money. When combined these factors generate higher profit margins, which epitomises the advantages that IoT offers.
Security risks posed by IoT
Smart technology can make things run much smoother, but when appliances are collectively reliant on the internet, there are great security risks. Concerns regarding smart speakers like Amazon Echo or Google Nest and the extent to which they collect data have been widely publicised in recent years. If hackers gained access to your Gmail account, they could quite easily gain access to the information that your Nest device has picked up, such as passwords and bank account details.
The threat is much worse on a corporate level as the breach of a small device could lead to a firm’s entire IoT network being compromised. At last month’s InfoSecurity Europe conference, one speaker recalled a client case whereby the hacking of a smart kettle led resulted in the capturing of confidential board meetings via a smart TV camera. Such incidents leave companies vulnerable to ransomware attacks, which can end up costing firms large sums.
Measures to protect IoT
There are some simple steps to prevent your IoT network being attacked:
