A quick recap In the previous article, we looked at the typical architecture of an end-to-end IoT solution and different components playing role in it. We also saw a couple of terms used in discussing IoT security. In this article, we will focus on end devices. We will consider factors which can influence device security making them vulnerable to hacking. We will also discuss different ways to make them safe. End devices End devices are generally small, have minimal hardware and limited intelligence. More commonly they are either sensors or actuators, sometimes a combination of both. There might be some local processing power present, but it cannot be taken for granted generally. Because of these reasons, they generally send data and understand a limited set of commands. Since these devices are small and relatively cheaper, they come with minimal provisions to configure them. This constrained ability and resources might sometime be a disadvantage to a hacker, because i

Scene 1   It’s a pleasant Sunday morning, a perfect weather and you are out on a long drive cruising a stretch of highway in your latest car. The same car which caused some sensation when you showed this latest techno-wonder to your friends. Today you feel lucky because there is almost no traffic at this hour. Your all-time connected car is constantly updating you about weather, road conditions, nearest places of interest and of-course your social feeds. You driving at moderate speed enjoying the drive. Suddenly something seems to be wrong. Without you doing so, your car starts accelerating, you feel engine revving up, steering wheel feels so heavy and the breaks seem so hard to apply. The car seems to be out of your control. Instead of showing the usual data, navigation panel in your car is showing some funny messages. Fortunately, after few minutes things seem to be under control again. But you are damn scared. Scene 2 Your neighbour has returned home after a major heart s
