Vulnerability discussion

Password strength is a measure of the effectiveness of a password in resisting guessing and brute force attacks. The ability to crack a password is a function of how many attempts an adversary is permitted, how quickly an adversary can do each attempt, and the size of the password space. A minimum level of complexity is needed to ensure a simple password or easily guessed password is not used.SFR ID: FMT_SMF_EXT.1.1 #47
