【摘要】 安全是评价分布式系统性能的重要指标,它可能在客户层、业务层或数据层实现。在数据层只有低级别安全控制能力的分布式系统中,往往在业务层实现附加的安全控制以保障整个系统的安全。本文分析了微软分布式企业应用框架(WindowsDNA)的业务层组件框架———MTS(Mi crosoftTransactionServer)的安全模型,并探讨了在数据层只有低级别安全控制的WindowsDNA应用系统中如何实现MTS的安全控制。更多还原

【Abstract】 Security is a key criteria for a distributed system,it can be realized at client layer、business layer or data layer. In these distributed systems with lower security at data layer, additional security control have to be realized at business layer to guarantee the whole system’s security. This paper analyzes a component frame of Windows DNA at business layer——MTS’s security model and discusses how to use it to protect the whole system in such Windows DNA system with lower security control at data layer.更多还原
