本章介绍智能客户端的安全性问题。智能客户端将逻辑和数据分布到客户端计算机；因此需要考虑的安全性和与瘦客户端应用程序相关的安全性是不同的，后者的数据和逻辑更多地被限制到服务器。本章讨论智能客户端应用程序中的数据安全性、身份验证、授权以及代码访问角色的安全性。-chapter describes smart client security issues. Smart client will be logic and data distribution to the client computer; Hence the need to consider the safety and FOR THIN CLIENT applications with the relevant safety is different. The latter data and more logical to be limited to the server. This chapter discusses the smart client applications of data security, authentication, authorization and role of the code access security.
