Authentication was externalised more than a decade ago, yet externalising authorization has proven elusive. With the rise of advanced threat actors, regulation, compliance and pressures for greater business agility, authorization is more relevant than ever, so what have we learnt and why may it be different this time? It is tempting to think of externalising authorization as a technology problem. Technology like policy languages, authorization engines and workflow systems are necessary to enable the externalisation of authorization, but it is not sufficient. External authorization requires three pillars to be in place namely, value for all stakeholders from engineers to customers, robust business processes and technology to support these. In this session we explore each of these pillars in terms of mapping value for all stakeholders, the process and culture needed to make authorization policies explicit and finally the need to drive authorization infrastructure, from policy language to enforcement engines, into the compute and network fabric to make authorization ubiquitous.
