A Survey of XML-based Security Standards for Handling Security Requirements of Grid and Cloud

The purpose of this paper is to present a survey of XML-based security standards that can be used for handling security requirements of distributed computing systems like Grid and Cloud. Distributed systems are expanding and their growth is apparent from the advancements in the field of distributed computing technologies like Grid, Peer-to-peer, Cloud, Pervasive Systems etc. As a result of this expansion, security requirements are also increasing and becoming important. The expansion of Grid and Cloud demands new security standards for handling specialized security requirements and concerns of these systems. Different security standards are in use for handling security requirements of different systems. This paper presents a survey of important XML-based security standards, identifies general and specialized security requirements of Grid and Cloud like systems and then relates them to security standards. The paper also presents a general, security standards based view of distributed computing systems showing the applicability of XML-based security standards in handling security concerns of these systems.
