With the exponential rise in the popularity and the implementation of Industrial Internet of Things, or as commonly called, IIoT, there has been a corresponding rise in the levels of security concerns in this arena. This is especially true in the case of industrial organizations as they are inclusive of smart devices which are networked and are responsible for operating heavy machinery and potentially dangerous systems.
In the past, there have been instances where massive nuclear centrifuges have been affected, as well as events where there were attacks on power grids, in particular in the zone dedicated to cyber warfare.
With such events in mind, there has been an aggregate concern regarding the safeguarding of the security levels where Industrial IoT has been involved.
Nevertheless, this situation is not without a solution. In this vein, enumerated below are a few practical tips that would be of great help to improve the levels of security in Industrial IoT.
Study the Situation
In the court of the manufacturer, there are several IoT devices that are equipped with the basic security controls, which in some cases might even be absent. In this scenario, the lack of standardization, deficient patch management, network issues and clarity of asset ownership are aspects that need to be taken into account and inspected thoroughly.
Know The Risks of Converging IT and OT
IIoT mandates the melange of IT and OT for it to work together. However, it is imperative that their discrepancies in purposes and functions, like the premier concern of IT being infrastructure, security and administration, whereas OT is more concerned with the aspects of yield, quality assurance and levels of efficiency, are accounted for as well. The enterprises must be meticulous in the relegation of responsibilities in the area of IoT so that the employees have a concretized goal to work for. In this context, it is also important to mention that IT and OT have differing approaches to the issue of security itself. Thereby, the evaluation of risk factors, inclusive of protocols, patching cycles, and the like would need to be looked into.
Segregate The Risk
It needs to be harped that risk (and risk factors) are not stagnated. The industrial organizations have to have legal ownership of IoT components and the ancillary systems as a rule. This is solely because the negative effects of IIoT malfunctions could be considerably worse than external IoT breaches.
In this case, alongside the security precautions for IIoT, the operations need to be considered as well. After the inspection and classification of the potential risks, an organization could very well construct a model to ensemble their security measures to counter and prevent this issue from manifesting.
