Description

The severity of cyber threats towards existing and future industrial systems has
resulted in an increase of security awareness in the industrial automation domain.
Compared to traditional information security, industrial communication
systems have different performance and reliability requirements. The safety
and availability requirements can also sometimes conflict with the system security
design of plants. For instance, it is not acceptable to create a secure
system which may take up additional time to establish security and as a consequence
disrupt the production in plants. Similarly, a system which requires
authentication and authorization procedures before any emergency action may
not be suitable in industrial plants. Therefore, there is a need for improvement
of the security workflow in industrial plants, so that the security can be realized
in practice. This also leads to the requirement of secure device deployment and
secure data communication inside the industrial plants.

In this thesis, the focus is on the initial trust establishment in industrial devices.
The initial trust establishment is the starting point for enabling a secure
communication infrastructure. Reusability analysis with financial sectors has
been considered as the reuse of security solutions from this adjacent application
domain can be a simple and an effective way to achieve the desired system security.
Through this analysis, the reusability features have been identified and
workflows have been proposed which can be used to bootstrap initial trust in
the industrial process control devices and manage security workflow. A proof-of-
concept implementation to prove the feasibility of the device deployment
workflow has also been provided.
