Aleph Insights was asked to develop a data framework that could be used to structure the MOD’s cyber data in a format which would enable easy sharing across all parts of the organisation and with partners. Rather than designing a whole new framework and introducing additional adoption barriers, we built on the most appropriate existing frameworks, designing and specifying a number of object extensions to meet the specific needs of the defence community. The comprehensive architectural artefacts developed by Aleph Insights are now being used as the basis for consistent data structuring by the client.
