The Internet of Things (IoT) and Edge Computing
are starting to go hand in hand. By providing cloud services
close to end-users, edge paradigms enhance the functionality of
IoT deployments, and facilitate the creation of novel services
such as augmented systems. Furthermore, the very nature of
these paradigms also enables the creation of a proactive de-
fense architecture, an immune system, which allows authorized
immune cells (e.g., virtual machines) to traverse edge nodes
and analyze the security and consistency of the underlying IoT
infrastructure. In this article, we analyze the requirements for
the development of an immune system for the IoT, and propose
a security architecture that satisfies these requirements. We
also describe how such a system can be instantiated in Edge
Computing infrastructures using existing technologies. Finally,
we explore the potential application of immune systems to other
scenarios and purposes
