Abstract

In the rapidly changing e-business environment, organizations need to share information, process business transactions, and enhance collaborations with relevant entities by taking advantage of the various technologies. However, there are always the security issues that need to be handled in order for the e-business operations to be run efficiently. In this research, we suggest the new security authorization model for safety flexible supporting the needs of e-business (e-marketplace) in an organization. This proposed model provides the scalable of access control policy among multi-domains, and preservation of flexible authorization management in distributed system environments. For servers to take the access control policy and enforcement decisions, we also describe the feasible authorization architecture is concerned with how they might seek advice and guideline from formal access control model.
