Practical Industrial Internet of Things Security

Building blocks of industrial IoT security architecture

For the three-tier architecture discussed in the previous section, the IIoT security architecture has to span end-to-end across the three tiers – from device endpoints at the edge, through the platform tier, and ultimately to the enterprise tier. In the case of layered databus deployments, the security framework needs to encompass the databus communication and schemas, the endpoints at each layer, and also the interlayer communication through the databus gateways. This proves the pervasive nature of IIoT security. Besides, security can't be bolted on as an afterthought, rather security risks should be evaluated early in the deployment lifecycle; and countermeasures must be built into ...
