Query: Putting Things in Context: Securing Industrial Authentication with
  Context Information   The development in the area of wireless communication, mobile and embedded
computing leads to significant changes in the application of devices. Over the
last years, embedded devices were brought into the consumer area creating the
Internet of Things. Furthermore, industrial applications increasingly rely on
communication through trust boundaries. Networking is cheap and easily
applicable while providing the possibility to make everyday life more easy and
comfortable and industry more efficient and less time-consuming. One of the
crucial parts of this interconnected world is sound and secure authentication
of entities. Only entities with valid authorisation should be enabled to act on
a resource according to an access control scheme. An overview of challenges and
practices of authentication is provided in this work, with a special focus on
context information as part of security solutions. It can be used for
authentication and security solutions in industrial applications. Additional
information about events in networks can aid intrusion detection, especially in
combination with security information and event management systems. Finally, an
authentication and access control approach, based on context information and -
depending on the scenario - multiple factors is presented. The combination of
multiple factors with context information makes it secure and at the same time
case adaptive, so that the effort always matches, but never exceeds, the
security demand. This is a common issue of standard cyber security, entities
having to obey strict, inflexible and unhandy policies. This approach has been
implemented exemplary based on RADIUS. Different scenarios were considered,
showing that this approach is capable of providing flexible and scalable
security for authentication processes.
