多级安全的分布式管理和动态行为

Distributed management and dynamic behavior for multi-level security

传统的多级安全模型和在模型指导下设计出来的多级安全系统存在集中式管理和缺乏明确的动态管理机制这两个重要问题.本文研究了多级安全的分布式管理体系和动态多级安全管理策略.给出一个基于域的多级安全分布式管理模型,该模型集成了域分离、域隔离和域冗余的域管理安全策略.着重讨论了多级安全的动态行为和规范这些行为的安全管理策略.分别论证了所提出的安全策略的有效性和可行性.

The centralized management and lack of dynamic multi-level security policies are two important limitations of the traditional multi-level security models and the real systems designed in light of them. This paper studies the distributed management and dynamic behavior for multi-level security. A domain-based distributed management model for multi-level security is presented. Several dynamic multi-level security policies are discussed. All the proposed security policies and present the corresponding implementation mechanism are analyzed.
