An overview of security challenges associated with IoT

IoT is the latest emerging technology. Experts estimate that there are already 25 billion connected devices across the world. Connected Cars, Smart TVs, Smart Refrigerators, Smart Watches, Smart Glasses – we can see a big list of applications of IoT in every aspect of our life.

Undoubtedly, there are many benefits of IoT, including ease of life, better productivity, health services, and better quality of life, just to name a few. But there are many risks as well, such as the invasion of privacy, ethics violation, a lack of standards, and more. Here is a list of security challenges associated with the IoT-enabled smart devices:

a. Insufficient testing and updates

b. Brute force and Botnet attacks

c. Malware and Ransomware

d. Data breaches

e. Lack of trust

f. User privacy

We can see security is one of the biggest challenges of IoT. What if the IoT solution gets hacked – the driving path, speed, and other parameters get altered for a self-driving car, your smart tv becomes host to DDoS attack, or your AC thermostat starts misbehaving? Well, the result is a disaster.

In the year 2015, Fiat Chrysler recalled 1.4 million vehicles due to a vulnerability in its system. The exploit was demonstrated by remotely taking control of the 2014 Jeep Cherokee. The experts were able to take control of various components including steering, braking system, engine, etc.

Smart appliances, smart health devices, and other smart sensors generate a huge amount of data that gets stored on the server-side for computation and generates feedback to the device or other applications. Individually, it might not be problematic if it gets leaked but collectively, if this data goes into the wrong hands, it could come back to us as a quite bigger threat later.

Individuals, meanwhile, should think about what kind of data they are producing and how that is managed. What are the policies and guidelines getting followed on how that information is stored and protected.
