Layer-wise Security Challenges and a Secure Architectural Solution for Internet of Things at Physical, Network and Application Layers
In recent years, the Internet of Things has emerged as one of the most important technologies of the twenty-first century. We can now connect everyday objects to the internet via embedded devices such as kitchen appliances, cars, thermostats, and baby monitors, allowing for seamless communication between people, processes, and things. Because of low-cost computing, the cloud, big data, analytics, and mobile technologies, physical things can share and collect data with minimal human intervention. In this hyper-connected world, digital systems can record, monitor, and adjust every interaction between connected things. The physical and digital worlds intersect and work together. By enabling connected cars, IoT is reinventing the automobile. The global market for connected cars is expected to grow significantly in the coming years as connectivity innovations transform the automotive industry. However, as with any other device that connects to the internet, cyber criminals pose a threat to automotive security. Personal data leaks, threats to a vehicle’s essential security and safety mechanisms, and, in extreme cases, full remote control of the vehicle can all result from security breaches. And, as the industry moves toward more self-driving vehicles, these risks are only going to grow due to increased reliance on applications, connectivity, and more complex and integrated electronic components. Failure to address these risks could have disastrous consequences for consumer trust, privacy, and brand reputation. Worse, customer safety is jeopardized. In this paper, the author discusses Layer-wise Security Challenges, Attack Vectors, and Architectural Flaws in the Physical layer by taking an example of a device connected to Connected cars and proposes a secure architectural solution for the Internet of Things (IoT) that assists in delivery teams in securely designing/architecting resource-intensive smart Internet of Things (IoT)/Narrowband (NIoT) use cases earlier in the Life cycle by employing the Secure Design Shift Left approach.
