What is IoT Security? Internet of things (IoT) is a collection of many interconnected objects, services, humans, and devices that can communicate, share data, and information to achieve a common goal in different areas and applications.
IoT has many implementation domains like transportation, agriculture, healthcare, energy production and distribution. Devices in IoT follow an Identity Management approach to be identified in a collection of similar and heterogeneous devices.
By 2025, it is expected that there will be more than 30 billion IoT connections, almost 4 IoT devices per person on average and that also amounts to trillions of sensors connecting and interacting on these devices. State of the IoT 2020: 12 billion IoT connections (iot-analytics.com). According to The McKinsey Global Institute, 127 new devices connect to the internet every second.
IoT mainly operates on three layers termed as Perception, Network, and Application layers. Each layer of IoT has inherent security issues associated with it.
An active attack directly stops the service while the passive kind monitors IoT network information without hindering its service. At each layer, IoT devices and services are susceptible to Denial-of-Service attacks (DoS), which make the device, resource or network unavailable to authorized users.
Typical security goals of Confidentiality, Integrity and Availability (CIA) also apply to IoT. However, the IoT has many restrictions and limitations in terms of the components and devices, computational and power resources, and even the heterogonous and ubiquitous nature of IoT that introduce additional concerns.
The security challenges of IoT can be broadly divided into two classes, Technological challenges and Security challenges. There are different mechanisms to ensure security including but not limited to: –
