Answer: C
The compromise of the password is the highest risk. The best
control is a preventive control through validation at the
time the password is created or changed. Changing the
company's security policy and educating users about the risk
of weak passwords only provides information to users, but
does little to enforce this control. Requiring a periodic
review of matching user ID and passwords for detection and
ensuring correction is a detective control.
