As new concepts for eSciene like grid computing and cloud computing tend to leave the research phase and develop towards production quality, the security eventually moves into focus. Up to now research in the security area concentrates on authentication and authorization on the resources themselves, but to enhance network security more generally, access control must be pushed back to the entry point...
A spatial data access control model in grid environment was proposed base on Globus Security Infrastructure (GSI). Firstly, A spatial datasets sharing framework was built up by Monitor and Discover Service (MDS), and then a common control model was proposed to realize spatial data access control. In this model, every user was mapped to a given role, and every role had a unique digital certificate...
Tycho was conceived in 2003 in response to a need by the GridRM [1] resource-monitoring project for a ldquolight-weightrdquo, scalable and easy to use wide-area distributed registry and messaging system. Since Tycho's first release in 2006 a number of modifications have been made to the system to make it easier to use and more flexible. Since its inception, Tycho has been utilised across a number...
Grid computing provides users with transparent access to substantial compute and storage resources. Up to now the main focus lay in the development of Grid infrastructures and the development of services providing access to grid resources. This leads to a negligence of security aspects, which, for example, leads to the recommendation of open wide port ranges on firewalls protecting the Grid resources...
Security is the condition that prevents unauthorized persons from having access to official information that is safeguarded in the interests of some particular purpose. Data security ensures that kind of private and sensitive data from corruption and the access to it is suitably controlled. Enterprise businesses and government agencies around the world face the certainty of losing sensitive data from...
