Abstract
In this paper, we present our ongoing work of a policy-driven approach to security requirements of grid data management systems (GDMS). We analyse the security functionalities of existing GDMS to determine their shortcomings that should be addressed in our work. We identify a comprehensive set of security requirements for GDMS followed by the presentation of our proposed Security Requirements Model. Derivation of security policies from security requirements and their consequent refinement is also presented in this paper. Our approach of addressing modelling issues by providing requirements for expressing security related quality of service is the key step to turn storage systems into knowledge representation systems.KeywordsGrid securityrequirements analysisdistributed data management
