Abstract

Due to the dynamic and multi-institutional nature, auditing is fundamental and difficult to solve in grid computing. In this paper, we identify security-auditing requirements, and propose a Cross-Domain Security Auditing (CDSA) architecture, in which mobile agent is applied to help gathering security information in the grid environment. Whilst a new authorization mechanism is presented to improve the performance by changing the traditional manner "route once, switch many" over the network into the "audit once, authorize many" in the Grid, and a multi-value trust relationship model is constructed in order to carry out the dynamic auditing. The system enforces these mechanisms to enable cross-domain security in the aid of special services based on Globus Toolkit version 3.0 and IBM Aglet.
