Internet of Things (IoT) Security Requirements: Issues Related to Sensors

The last couple of years have seen IoT-enabled sensors continuing to experience massive growth. Sensors have enhanced the possibility of large-scale IoT deployments in grid systems, vehicles, homes, and so forth. A network that incorporates different embedded systems has the underlying capability of transmitting information and receiving instructions through distributed sensor networks. Sensors are especially essential in gathering different pieces of information that relate to different IoT devices. However, security has become a critical concern for sensor networks that are enabled by the IoT. This is partly because of their design limitations like limited memory, weak processing capability, weak processing ability, and exposure to entities that are malicious. Even more, some ad hoc wireless sensor networks that are enabled by IoT are to some extent also prone to frequent changes in topology. This dynamic aspect tends to aggravate the security issues that are associated with sensors, thus enhancing the need to find a lasting solution. This paper sheds light on the IoT security requirements with special attention to issues related to sensors.
