This thesis deeply researches the J2EE security strategy on the application tier of enterprise system. The security strategy predigests the information security model and meets the security requirements expediently. But there are some disadvantages when the security requirements become more complex. The expositive security on the Web-Tier can not offer more information for authentication; there is no authentication for EJB-Tier to use, make the EJB-Tier depend on the Web-Tier; J2EE uses database or application server to manage the role information. Use database to manage the role information will increase the complex of enterprise application, and the way of application server will reduce the ability of migrate other J2EE platform. To solve these problems, the thesis designs an improved security strategy model.

本文从企业级系统应用层安全的角度出发，深入研究J2EE多层体系结构的安全策略模型。J2EE提供的安全策略简化了系统的信息安全模型，能够很方便地满足基于J2EE的分布式应用系统的安全需求，但是在面对更加复杂的安全需求时，J2EE安全策略在验证授权和角色管理中还存在不足之处：其在Web层的声明式验证机制无法为用户提供更多验证信息，可扩展性较差；在EJB层缺少业务逻辑层可供采用的验证机制，而是借助于Web层的验证机制，其耦合程度较高有悖于业务逻辑分离于表现逻辑的原则；在角色管理方面，J2EE采用数据库或者应用服务器来管理角色信息，其中，数据库管理角色的方式增加了应用开发的复杂度，应用服务器管理角色降低了系统的可移植性，两者都具有片面性。
