Access Rules Enhanced by Dynamic IIoT Context

The Industrial Internet of Things is a fast-growing business with many opportunities but also security risks. For instance, a crucial risk is an attack on customer’s or company’s internal data to violate the integrity, like order information or machine configurations. In addition, an attacker could inject packets which contain harmful manufacturing machine tool commands. This work introduces a novel rule-based approach which uses subcontexts of the Industrial Internet of Things (IIoT) context for deep packet inspection to protect the privacy of data and to increase the resilience of the system against attacks. Furthermore, formal definitions for the Industrial Internet of Things context, subcontexts and context rules have been investigated and developed. The subcontexts are used in combination with a new protocol called context enhancement protocol, to add context information to packets.
