【摘要】 传统的用户名加口令和访问控制列表机制已经不能适应电子政务的进一步发展,本文运用分布式访问控制模型来解决这一问题。该模型把安全管理分为两层:第一层为全局安全管理层,它负责协调控制政务网所有控制对象的安全管理;第二层为局部安全管理层,它负责本部门或本项目组内对象的安全管理。通过对FreeBSD 5.0 RC2版内核的重新编译,实现上述访问控制模型。更多还原

【Abstract】 Since the method of using username and password and the traditional access-control list mechanism can no more keep up with the further development of E-Government,a distributed-access-control model is realized to settle this problem.This model divides the security management into two levels: First is global security management level which is responsible for harmonizing and controlling the security management of all the control objects of the e-government network;Second is local security management level which is in charge of the security management of local departments or objects inside local project group.By recompiling the kernel of FreeBSD 5.0 version RC2,the access control model described above is realized.更多还原
