SERSCIS

Integral to system governance is the concept of a Service Level Agreement (SLA). SERSCIS is reviewing a number of existing SLA languages, including GRIA SLAs, SLAng, WSLA and WS-Agreement to ascertain their extensibility for the description of dependability metrics and guarantees. Management models and mechanisms, such as WS-Management, WSDM and the proposed convergence of these two standards, are also under review. In order to enforce the terms of an SLA, security policy representations including PBAC, XACML and SecPAL are being considered.
