December - 2019ENTERPRISE SECURITY| | 9Best practices to adoptThe threats and vulnerabilities are manifold, so there is currently no silver bullet for securing IoT. However, business and organisations can still implement a few best practices that will aid them in securing the IoT offerings, as shown below.IoT is at an inflection point and expanding rapidly into mission-critical areas, especially with the imminence of 5G.Security and privacy concerns will be the biggest hindrances to IoT adoption and growth, and therefore enterprises must seek to implement robust security measures to alleviate these apprehensions. Additionally, governments must focus on driving unified standards/regulations for IoT security that don't exist today, while those in academia must disseminate learnings to all the key stakeholders and increase research focus on IoT security. To strengthen trust in IoT, all the stakeholders need to join together and dedicate themselves to making IoT security a mandatory aspect and a crucial point of integration into their operations. ESarchitecture of an IoT system, the functionality assumed by the components, the data, and the control flow across the systems involved.It is impossible to make any IoT solution comprehensively secure. However, understanding the possible vulnerabilities across different layers and the corresponding threat vectors, coupled with adoption of best practices, can certainly strengthen the security position of IoT solutions. Possible vulnerabilities and threat vectorsIoT systems tend to be intricate and heterogeneous; they include multiple tiers, technologies, deployment locations, device manufacturers, APIs and much more. From a security standpoint, end-to-end IoT systems have numerous vulnerabilities across different strata, encompassing multiple components that are each subjected to distinctive attacks. Below is a summary of possible vulnerabilities and corresponding attacks that can affect each of the componentsThere are a myriad threat vectors, and so attacks can ensue with or without any human involvement. Also, the scale of the infection spread is very high and rapid in case of IoT, making the negative ramifications even more pronounced. For instance, there are several focused and evolving malwares exploiting the vulnerabilities across different levels of an IoT solution.
