What's Systems Security all about?
This category within the Cyber Body of Knowledge, covers 4 wider knowledge areas:
Cryptography - core primitives of cryptography as presently practised and emerging algorithms, techniques for analysis of these and the protocols which use them.
Operating Systems & Virtualisation Security - operating systems protection mechanisms, implementing secure abstraction of hardware and sharing of resources, including isolation in multi-user systems, secure virtualisation and security in database systems.
Distributed Systems Security - security mechanisms relating to larger scale coordinated distributed systems, including aspects of secure consensus, time, event systems, peer-to-peer systems, clouds, multi-tenant data centres, and distributed ledgers.
Authentication, Authorisation & Accountability (AAA) - all aspects of identity management and authentication technologies, and architectures and tools to support authorisation and accountability in both isolated and distributed systems.
