In 2015, a group of security researchers hacked a Jeep, turned its windshield wipers and air conditioners on and then stopped the functioning of the accelerator. Not only this, they said that they were capable of disabling the engine and the brakes. They could do it by infiltrating the vehicle’s network through manufacturer Chrysler’s in-vehicle connectivity system, Uconnect.
In another instance of IoT security vulnerability, in October 2016, when a hacker exploited a loophole in a specific model of the security camera, more than 300,000 video recorders started to attack many social network websites. This brought down Twitter and other platforms for more than two hours.
The examples above shed light on the vulnerability of IoT and what can happen to IoT systems with poor security apparatus.
According to market analysis, the IoT connected devices worldwide are estimated to reach over 60 billion by the end of 2025. The rising worldwide popularity of IoT usage is unexpected as it brings with it several business advantages across all the industries. The advantages include increased efficiency and cost savings among others wherever IoT is used. However, along with varieties of benefits and advantages come several daunting security challenges at all levels.
