  Imagine interconnected objects with embedded artificial intelligence (AI),
empowered to sense the environment, see it, hear it, touch it, interact with
it, and move. As future networks of intelligent objects come to life,
tremendous new challenges arise for security, but also new opportunities,
allowing to address current, as well as future, pressing needs. In this paper
we put forward a roadmap towards the realization of a new security paradigm
that we articulate as intelligent context-aware security. The premise of this
roadmap is that sensing and advanced AI will enable context awareness, which in
turn can drive intelligent security mechanisms, such as adaptation and
automation of security controls. This concept not only provides immediate
answers to burning open questions, in particular with respect to non-functional
requirements, such as energy or latency constraints, heterogeneity of radio
frequency (RF) technologies and long life span of deployed devices, but also,
more importantly, offers a viable answer to scalability by allowing such
constraints to be met even in massive connectivity regimes. Furthermore, the
proposed roadmap has to be designed ethically, by explicitly placing privacy
concerns at its core. The path towards this vision and some of the challenges
along the way are discussed in this contribution.
