求教 GWD - 31 - Q12 一个选项的理解~~~~
Secret passwords are often used to control access to computerswhen employees as 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?
A.If passwords are generated randomly, it is theoretically possible that employees will be assigned passwords that they might have selected on their own.
B.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.
C.Computer systems protected by passwords are designed to ignore commands that are entered by employees or others who use invalid passwords.
D. 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.
E. 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
OA:B
正确答案B我明白,可是A为什么不对呢?我的理解A是虽然passwords可以随意设定,但是员工自己能够修改,这样的话不是还是削弱了argument里面要improve secrurity的目的么~~ 难道是我A选项里面theoretically的理解有问题~ |
