Secret passwords are often used to control access to computers. When employees are allowed to make up their own passwords, they are likely to setup as passwords their initials or birth dates. To improve security, employers should assign randomly generated passwords to employees rather than allowing employees to make up their own

Which of the following, if true, most seriously undermines the conclusion drawn above?

If passwords are generated randomly, it is theoretically possible that employees will be assigned passwords that they might have selected on their own. Randomly generated passwords are so difficult for employees to recall that they often record the passwords in places where the passwords could be easily seen by others. Computer systems protected by passwords are designed to ignore commands that are entered by employees or others who use invalid passwords. In general, the higher the level of security maintained at the computer system, the more difficult it is for unauthorized users to obtain access to the system. Control of physical access to computers by the use of locked doors and guards should be used in addition to passwords in order to maintain security

题干翻译
当员工设置密码时，他们很可能设置自己的姓名首字母或出生日期作为密码。为了提高安全性，雇主应该给员工分配随机生成的密码，而不是让员工自己设置密码。 逻辑链
员工自设密码不安全→随机分配密码 问题类型
削弱题。 推理过程
题干认为因为员工自设密码不安全，所以要采用随机分配密码的方式来提高安全性，我们需要找到能说明随机分配密码也无法提高安全性的选项。 选项分析
A选项：随机生成的密码理论上可能是员工自己会选的密码。但这并不能说明随机生成密码就不安全，无法削弱，排除。 B选项：随机生成的密码很难记住，员工常常把密码记在容易被他人看到的地方。这表明随机生成密码会带来新的安全隐患，无法提高安全性，有力地削弱了结论，当选。 C选项：受密码保护的计算机系统会忽略无效密码输入。这与随机生成密码是否能提高安全性没有直接关系，排除。 D选项：一般来说，计算机系统维护的安全级别越高，未经授权的用户越难访问系统。这是在说安全级别和访问难度的关系，与随机生成密码的安全性无关，排除。 E选项：除了密码之外，还应使用锁门和警卫来控制对计算机的物理访问以维护安全。讨论的是其他安全措施，与随机生成密码能否提高安全性话题不一致，排除。
