Abstract
Globus Toolkit version 4 (GT4) leads to a set of new services and tools. This is the culmination of a first step towards the migration to web services from previous Globus Toolkit versions. GT4 directly addresses basic issues, in the form of services, inherent to any distributed system like, for example, security, resource discovery, data movement and management, etc. However, we believe that an advanced management is still needed in the framework, in order to provide a system-wide view of these services. This is especially true in the case of security related services. They must be properly managed all across different collaborating organizations within the grid infrastructure. This paper presents the major achievements when designing and developing a semantic-aware management framework for GT4 security services.
