A security administrator wants to check user password complexity. Which of the following is the
BEST tool to use?

A.
Password history

B.
Password logging

C.
Password cracker

D.
Password hashing

Explanation:
The most important countermeasure against password crackers is to use long, complex
passwords, which are changed regularly. Password-cracking tools compare hashes from potential
passwords with the hashes stored in the accounts database. Each potential password is hashed,
and that hash value is compared with the accounts database. If a match is found, the passwordcracker tool has discovered a password for a user account.
