试题五(25 分)阅读以下关于信息系统安全性的叙述,在答题纸上回答问题1 至问题3。某企业根据业务扩张的要求,需要将原有的业务系统扩展到互联网上,建立自己的B2C 业务系统,此时系统的安全性成为一个非常重要的设计需求。为此,该企业向软件开发商提出如下,要求:(1)合法用户可以安全地使用该系统完成业务;(2)灵活的用户权限管理;(3)保护系统数据的安全,不会发生信息泄漏和数据损坏;(4)防止来自于互联网上各种恶意攻击;(5)业务系统涉及到各种订单和资金的管理,需要防止授权侵犯;(6)业务系统直接面向最终用户,需要在系统中保留用户使用痕迹,以应对可能的商业拆讼。该软件开发商接受任务后,成立方案设计小组,提出的设计方案是:在原有业务系统的基础上,保留了原业务系统中的认证和访问控制模块;为了防止来自互联网的威胁,增加了防火墙和入侵检测系统。企业和软件开发商共同组成方案评审会,对该方案进行了评审,各位专家对该方案提出了多点不同意见。李工认为,原业务系统只针对企业内部员工,采用了用户名/密码方式是可以的,但扩展为基于互联网的B2C 业务系统后,认证方式过于简单,很可能造成用户身份被盗取;王工认为,防止授权侵犯和保留用户痕迹的要求在方案中没有体现。而刘工则认为,即使是在原有业务系统上的扩展与改造,也必须全面考虑信息系统面临的各种威胁,设计完整的系统安全架构,而不是修修补补。

【问题3】(8 分)请解释授权侵犯的具体含义;针对王工的意见给出相应的解决方案,说明该解决方案的名称、内容和目标。
