摘要
访问控制在信息系统中是个重要的保护机制.访问控制加强了主体对访问对象的限制,使得合法用户可以访问到需要访问的对象,非法用户则不可以越权获得数据,由此可以看出访问控制是多用户和多对象的工作流管理系统当中非常重要的安全管理技术.如果这些访问控制方面较为复杂的规则采用XML描述就会大大提高工作流系统在管理用户的访问控制这些较为复杂的事务方面的安全性与平台的无关性.
Access Control in Information System is an important protection mechanism. It strengthens the restraint to the objects so that the legitimate subjects can visit what they want to visit but unauthorized users can not access data beyond his or her authority. So the access control is a very important technology in a multi-user and multi-object world＇low management systems. If these access control rules are described by XML, the safity of the workflow in managing compound transactions and platform independence will be greatly enhanced.
