CompTIA Security+ Question E-30

A security administrator is concerned about the strength of user’s passwords. The company does not want to implement a password complexity policy. Which of the following can the security Administrator implement to mitigate the risk of an online password attack against users with weak passwords?

A. Increase the password length requirements
B. Increase the password history
C. Shorten the password expiration period
D. Decrease the account lockout time

Answer: C

Reducing the password expiration period will require passwords to be changed at the end of that period. A password needs to be changed if it doesn’t meet the compliance requirements of the company’s password policy, or is evidently insecure. It will also need to be changed if it has been reused, or due to possible compromise as a result of a system intrusion. This will give online password attackers less time to crack the weak passwords.
