D.It allows an administrator to configure and manage how identification t

44、akes place within the network.解析：解析：C 正确。大多数企业都有包含公司网络资源和用户信息的某种类型的目录。基于 X500 标准(不是 X509)和一种协议类型，即轻量目录访问协议(Lightweight Directory Access Protocol，LDAP)，大多数目录都遵循分层的数据库结构，允许主体和应用程序与这个目录进行交互。应用程序可以通过向目录提出一个 LDAP 请求来获得某一特定用户的信息；用户也可以使用相似请求获得某个特定资源的信息。目录服务基于 X500 标准，给数据库中的每个客体分配一个 LDAP 可访问的可分辨名称(distingui

45、shed names)。每一个可分辨名称都代表着某个特定客体的属性的集合，并作为一个条目存储在目录中。 A 不正确。因为层次数据库中的客体都是通过日录服务进行管理的。目录服务允许管理员配置和管理网络内的身份识别、身份验证、授权和访问控制如何进行。目录内的客体都被贴上标签并用命名空间来标识，这也是目录服务保证客体有序的方式。 B 不正确。因为目录服务的确通过控制访问和身份管理功能加强了配置好的安全策略。例如，当用户登录到 Windows 环境中的一个域控制器时，目录服务(活动目录，Active Directory)便可以确定出他能访问哪些网络资源，不能访问哪些资源。 D 不正确。因为目录服务的确

46、允许管理员配置和管理网络内部身份识别的方式。它同时也允许对身份验证、授权和访问控制进行配置和管理。2.Hannah has been assigned the task of installing Web access management(WAM) software. What is the best description for what WAM is commonly used for?（分数：2.00）A.Control external entities requesting access through X.500 databasesB.Control external enti

47、ties requesting access to internal objects C.Control internal entities requesting access through X.500 databasesD.Control internal entities requesting access to external objects解析：解析：B 正确。Web 访问管理(Web Access Management，WAM)软件控制着用户在使用 Web 浏览器与基于 Web 的企业资产进行交互时能访问的内容。随着电子商务、在线银行、内容提供和 Web 服务等使用的日益增长，这

48、类技术变得越来越强大，应用也越来越多。Web 访问控制管理流程中最基本的部分和活动如下： a)用户向 Web 服务器发送证书； b)Web 服务器验证用户的证书； c)用户请求访问某个资源(客体)；d) Web 服务器使用安全策略确定是否允许该用户执行此操作： e)Web 服务器允许拒绝访问请求访问的资源。 A 不正确。因为目录服务应该在 X500 数据库不是 Web 访问管理软件的目录中进行访问控制。目录服务管理入口和数据，并通过实施强制访问控制和身份管理功能来巩固已配置的安全策略。活动目录和 NetWare 目录服务(NDS)就属于目录服务的例子。尽管基于 Web 的访问请求可能针对的是数

49、据库中的客体，但 WAM 主要控制 Web 浏览器和服务器之间的通信。Web 服务器通常通过目录服务与后端数据库进行通信。 C 不正确。因为当内部实体使用 LDAP 请求访问 X500 数据库时，目录服务应该执行访问控制。这种类型的数据库为所有客体(主体和资源)提供了一种分层结构。目录服务为每一个客体制定一个独一无二的可分辨名称，并根据需要将对应的属性追加到每个客体后面。目录服务实行安全策略(由管理员配置)来控制主体和客体的交互方式。如果基于 Web 的访问请求针对的可能是数据库中的客体，WAM 主要控制的是 Web 浏览器和服务器之间的通信。尽管 WAM 可以用于内部到内部的通信，但它主要是为了外部到内部的通信而开发的。B 选项是这 4 个选项中的最佳答案。 D 不正确。因为 WAM 软件主要用于控制外部实体对内部客体的请求访问，而不是这个答案项所描述的。例如，银行可能会使用 WAM 控制顾客访问后端账户数据。3.There are several types of password management approaches used by identity management systems. Which of the following reduces help-desk call volume, but is also cri
