The IoT market is projected to hit the $1.5 Trillion mark by 2025. Doesn’t that number look staggering? Putting in perspective, it’s a 600% growth from 2019, when the IoT market was pegged at $250 Billion. It is expected that 25 billion devices will be a part of the IoT network by 2025 with smartphones making 24% or 6 billion of the total devices. The biggest beneficiary of the IoT revolution is Industry 4.0. The IoT revolution can take off only if we can secure troves of data flowing through billions of IoT connections. This brings us to the focus point – IoT Security. IoT Security – The key that unlocks Industry 4.0 IoT security involves securing software, hardware, and networks that store, handle, collect, transmit, and process data. Be it your garage shutter, rolling up when your car enters your home perimeter, or your lights turning on the moment you enter the room, work on sensors. These sensors collect and send the data to a Command Center, which then processes and sends the response. This data needs to be secured. Your devices need to be secured. The entire network needs to be secured. This is what IoT security deals with. It comprises tools, strategies, and methods to secure you from bad actors who constantly keep coming back to find vulnerabilities in your networks. Unlike device-based security, like a smartphone or a laptop, IoT security is cloud-based. It is the fundamental block of the IoT – Big Data – Cloud Computing ecosystem. While IoT devices help in generating and collecting the data, the Big Data platform deals with analytics. The cloud computing system stores, processes, and addresses other aspects related to data mobility. IoT security ensures that everything taking place in the cloud and within the IoT devices is well protected. “The fate of Industry 4.0 is in the hands of IoT security and not just IoT device interconnectivity”, opines major players in Technology, Industries, Logistics, Commerce, and Government agencies. To tackle IoT Security challenges, Sectrio believes in the deployment of a robust IoT security management plan. At a design level, adopting security-by-design architecture is the best way to prevent and mitigate IoT security threats and vulnerabilities. A network without IoT Security is a house without a roof! What would it be like to lose control over a 100-Tonne machine on an industrial site? What would happen if a subway railway signaling system fails? It’s even difficult to imagine. Complex systems like power distribution, water management, traffic management, smart homes, and a ton of other systems and devices are interconnected via IoT devices, forming complex networks.

Any compromise on the security of these complex networks can lead to a catastrophic event. If a military network, nuclear plant network, or power transmission grid is compromised, the threat could be at a national level. Robust IoT security is imperative for complex and sensitive networks which keep this world on its wheels. From a cybersecurity expert’s POV, there are a host of IoT security challenges that a cybersecurity team has to deal with. Let us take an example of a smart automotive manufacturing factory. The functioning and competence of the factory highlight what the IoT revolution has to offer with time. On the other side, the same factory is a strong case to understand how important IoT security is. Upon infiltrating the factory’s network, hackers can get access to key systems and processes running on the factory floor. It’s only a matter of time before they get control over ‘privilege escalation’ permissions. In the case of our automotive manufactory factory, hackers can tinker with the settings of a manufacturing unit or an assembly unit, putting hundreds of lives in jeopardy. Similarly, if they manage to enter a Medical Command Control that monitors hundreds of medical devices like artificial pacemakers, there is a chance for greater human loss. Even in-home gadgets like CCTVs, Smart TVs, Smart Refrigerators, and others are not safe. These devices are configured to the home networks without their default credentials being changed. This puts the entire network at risk and the mercy of bad actors. It is important to have all endpoints of a network secured. The data passing between the devices and the cloud should be encrypted at all times. This mitigates the risk even during a data breach. Understanding the IoT Security Framework Most guides based on various IoT Security frameworks strictly depend on protocols and pre-defined policies that are actioned via the cloud. Depending on the nature of the industry, level of data collected, data processing, and other parameters, enterprises meet certain compliance standards as required by local laws. While this holds good for secure data processing on the IoT device, even manufacturers and consumers should be cognizant of their practices. IoT Security Framework is primarily spread across three levels: Physical Layer: 1. Security-by-design IoT Security by design should be strictly implemented. The development team should consider the ‘security’ feature as important as the device itself, being embedded into the SoC (System on Chip). This minimizes IoT security threats during the lifetime of the IoT device. Patch and firmware updates should be provided only through a secure mechanism. 2. Accessing the device At all times, user access credentials should be confidential and private. To prevent ‘brute force’ unlocking and abusive login attempts, steps should be undertaken. A thorough IoT security testing can help minimize IoT security risks. MFA should be mandatory to access sensitive data. 3. Detection and Anti-tamper Mechanism Manufacturers should ensure that no tampering with the IoT device can take place with minimal tools during shipping and installation. A comprehensive detection system should be in-built to alert the command control if needed. Complying with certain security certifications can help consumers make better choices in buying IoT devices. This is of primary importance owing to the
