In my opinion, six parameters drive data security and data architecture in the IIoT framework. These are management, quality, governance, integration, analytics and privacy.
This step defines standards for data aggregation and for enabling right access across different levels. There are multiple layers and sources of data that are addressed to avoid information chaos.
The quality of the data is determined by its source, further dependent on how updated and automated the machines are. Good data quality helps provide insights which are based on relevant analytics, in real-time. Legacy systems without necessary upgrades may not provide data that can be successfully used in the IIoT framework. This step may also reveal areas where data quality is poor or non-existent.
Data is now amongst the most valuable company assets and needs stringent access controls. Data governance determines where the feed comes from, how it is analyzed, and who can access what data. The extension of this is finalizing insights that are helpful and relevant for diverse stakeholders to create a comprehensive platform.
The entire management-quality-governance data cycle influences the choice of protocols, data centers and edge gateways that are deployed as part of the IIoT architecture.
The key to analytics lies in knowing what data from aggregated sets are to be used, and the insights that should be delivered. Assets have to be optimized in a digitalized environment to enable predictive models. It is important, therefore, to get the choice of IIoT architecture right based on the plant and its readiness for Industry 4.0.
The volume of data and impact on business mean privacy requirements that are greater than ever before. Remote access to systems and data increases the probability of unauthorized access and cyberattacks. Privacy extends from personal data and data security to IT security. Processes must, therefore, be defined at the planning stage itself.
