Description
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. The longer the minimum length of the password is, the larger the password space. Having a too-short minimum password length significantly reduces password strength, increasing the chance of password compromise and resulting device and data compromise. SFR ID: FMT_SMF_EXT.1.1 #1a
