【摘要】 对通用访问控制框架(GFAC)进行了研究,提出了一种基于J2EE的通用访问控制框架(JGFAC),并给出了其基于Java技术的实现。采用代理机制实现了多种安全策略的共存;通过对URL请求过滤有效控制了对系统资源的访问,并基于此实现了统一的授权管理。更多还原

【Abstract】 On study of GFAC(Generalized Framework for Access Control),this paper proposes a J2EE-based GFAX(JGFAC) and details its implementation using Java technology.To achieve the coexistence of multi-policy,it introduces a proxy mechanism.It also proposes a unified method to protect system resource and manage permissions,by enforcing access control on URL request.更多还原
