An architecture to manage security operations for digital service chains

Evolving business models are progressively pushing for increasing digitalization of existing and novel processes. The ICT industry is already addressing this need by massive introduction virtualization paradigms tight integration with the physical environment, which allow creation multi-domain complex service chains. Emerging technologies undoubtedly bring more agility in deployment operation but also break traditional security models, have not been conceived dynamic multi-tenancy environments. In paper, we briefly elaborate on gaps research challenges towards advanced assurance protection trustworthy reliable chains spanning multiple administrative domains heterogeneous infrastructures. We consolidate our analysis a reference architecture, includes all functional elements to effectively tackle agile nature emerging paradigms.
