TSSG recently became a contributing member of the OASIS international standardisation organisation. OASIS (the Organization for the Advancement of Structured Information Standards) is a non-profit consortium that drives the development, convergence and adoption of open standards for the global information society. Its members produce standards for security, Cloud computing, SOA, Web services, the Smart Grid, electronic publishing, emergency management, and other areas.
TSSG’s main current interest in OASIS relates to standardisation of the eXtensible Access Control Markup Language (XACML) a language used to express rules that govern users’ acess to computing resources in IT systems. TSSG researchers Dr Brendan Jennings, Dr Steven Davy and Bernard Butler have a strong interest in XACML and have done significant work on the both the authoring/analysis of XACML rules and on the performance of XACML rule evaluation. TSSG’s work on this area was recently present to the OASIS XACML technical committee and the team are planning their further engagement in XACML standardisation activities.
