参考解析
解析：
分析为了适应当今的快速竞争环境，组织正逐步允许承包商、合作伙伴、访问者和顾客访问它们的企业内部网络，这些用户可以在会议室或办公室通过有线端口连接网络，或通过无线访问点。在这种允许第三方进行的开放式访问中，局域网变得难以防守。第三方可能以各种方式带来风险，从用一台受感染的膝上型计算机到连接未授权访问的网络资源进行恶意活动。然而，对很多组织而言，考虑到操作的复杂性和保证系统安全的成本，第三方网络访问是禁止的。接受调查的注册信息安全管理人员中，有52%的人表示他们目前使用防火墙，而且承认在内部的防御措施是脆弱的。来自内部用户的威胁也正在逐步成为安全考虑的一个因素。怀有恶意的员工可能发起拒绝服务攻击或通过窥探网络窃取机密信息。当移动的和远程的用户访问网络时，他们一不小心就会使网络感染来自未受保护的公众网络的病毒和蠕虫。黑客伪装成内部用户，会利用脆弱的内部安全获得访问机密信息的权限。

问答题Most U.S. businesses, large or small, belong to what is called the private enterprise system. 1)This means simply that firms operate in a dynamic environment where success or failure is determined by how well they match and counter the offerings of competitors. Competition is the battle among businesses for consumer acceptance. 2)Sales and profits are the yardsticks by which such acceptance is measured.3)The business world has abundant examples of firms that were once successful but that failed to continue satisfying consumer demands.Competition assures that, over the long run, firms that satisfy consumer demands will be successful and those that do not will be replaced. The private enterprise system requires that firms continually adjust their strategies, product offerings, service standards, operating procedures, and the like. 4)Otherwise the competition will gain higher shares of an industry’s sales and profits.Consider the following cases. A P was long the largest supermarket chain. Now Safeway is the largest, and A P is attempting a recovery. Ford once was the dominant automaker. Today, it is second to General Motors, among domestic producers. These events suggest the dynamic environment of the private enterprise system. 5)Competition is a critical mechanism for guaranteeing that the private enterprise system will continue to provide the goods and services that make for high living standards and sophisticated life styles.Few organizations that offer a product or service can escape the influence of competition. The American Cancer Society competes for contributions with the American Heart Association, your own college, and other nonprofit enterprises. The armed forces compete in the labor market with private employers. Even the U.S. Postal Service faces competition. United Parcel Service competes for package shipments. Express Mail faces competition from Western Union’s mailgrams. And firms like The Mailbox, which rents post office boxes in the Seattle area, compete for the post-office-box business.
