     One day Walt Disney had a vision. It was a vision of a place where children and parents could have

fun together. The more Walt dreamed of a "magical park," the more imaginative and elaborate it became.

     The original plans for the park were on 8 acres next to the Burbank studios where his employees and

families could go to relax. Although, World War II put those plans on hold. During the war, Disney had

time to come up with new ideas, and creations for his magical park. It was soon clear that 8 acres

wouldn't be enough.

     Finally in 1953, he had the Stanford Research Institute conduct a survey for a 100-acre site, outside

of Los Angeles. He needed space to build rivers, waterfalls, and mountains; he would have flying

elephants and giant teacups; a fairy-tale castle, moon rockets, and a scenic railway; all inside a magic

kingdom he called "Disneyland."

     The search for the best venue for the park ended in the rural Anaheim, California with a purchase of a

160-acre orange grove near the junction of the Santa Ana Freeway (I-5) and Harbor Boulevard.

     Construction for Disneyland began on July 21, 1954, 12 months before the park was scheduled to

open.

     Some 160-acres of citrus trees had been cleared and 15 houses moved to make room for the park.

However, when the real designing came around, Disney met with inevitable questions. How do you make believable wild animals, that aren't real? How do you make a Mississippi paddle ship? How do you go

about building a huge castle in the middle of Anaheim, California? Disney asked his movie studio staff for

answers. The design of Disneyland was something never done before.   There would be four uniquely

different theme parts: Adventure land , Frontier land , Fantasyland Tomorrow land. Bit by bit, Disneyland

got ready for   Opening Day. The staff worked around the clock to get ready.

     But opening day was a terrible disaster. Beside the terrible opening day conditions, the park did

eventually pick up. By 1965, ten years after opening day, 50 Million visitors had come through the gates.

信息系统安全

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,不会发生信息泄露和数据损坏。

④防止来自于互联网上的各种恶意攻击。

⑤业务系统涉及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,以应对可能的商业诉讼。

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。

认证是安全系统中不可缺少的环节,请简要描述主要的认证方式,并说明该企业应采用哪种认证方式。
