What is IoT Security?

The activities, design, and processes put in place to safeguard and secure the IoT devices, their communication channel is covered under IoT security.

IoT devices or “things” as they are called have unique identifiers and all most all of them generate data in some form. These devices could be connected to sensors, actuators, mobile phones and/or with could server either directly or indirectly. IoT devices collect a lot of data depending on their usage and domain. IoT devices have capabilities to transmit data when connected to a network or another device. Since, IoT devices can collect data, generate data, process data and transmit data they are prone to attacks from unauthorized  and unwanted users.

Objectives of attackers could be anything from just getting to know how data is collected to intercepting data and changing the data either at collection point or during the transmission. The attack could be to reach to sensitive information about the user of the IoT device or manipulate the information coming out IoT device to benefit the attacker or somebody else.

There are a lot of ways to safeguard IoT devices right from having the right Operating System on the devices to secure device access through strong credentials, from encrypting data for communication to applying various layers of firewalls in the network.

IoT security has many challenges today as the number of IoT devices are growing at very fast pace. There millions of devices already in the market and are used by consumers. Thousands of devices are getting connected to the internet each day, making IoT devices prey for attackers. Security vulnerability could come from many aspects like devices released with old and unpatched operating systems, devices not having the ability to update their firmware or operating systems, users not changing the default credentials provided for device set up.

A lot of advancements have been made in product design, operating system, authentication methods to address various security pain areas but there is a long road ahead. No matter how much we progress security will always be of prime importance for IoT devices.

What is Internet of Things?

Internet of Things is nothing but a network of physical devices connected to each other on a computer based network. The devices here could be anything like a refrigerator, door look, microwave, lights, fitness bands, phones …just about anything you can imagine. The devices have software, sensors, actuators and microcontroller embedded in them which helps these devices to connect to a computer based network system. Using the sensors, microcontroller and the software the performance and behavior of these devices can be controlled remotely through a computer or mobile phone. The sensors in the devices help to record various data points, the microcontrollers can be programmed to take specific actions based on the data recorded – the data can also be sent to a cloud server for storage depending on the application on the device. IoT devices have application in wide range of areas, nowadays they are everywhere from manufacturing, healthcare, pollution monitoring to flood and environment monitoring to agriculture, animal husbandry to home and more.
