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.
This validation procedure is performed on both the MDM Administration Console and the Samsung Knox for Android device. Check whether the appropriate setting is configured on the MDM Administration Console: 1. Ask the MDM administrator to display the "Min Length" setting in the "Android Password Restrictions" rule. 2. Verify the value of the setting is the same or greater than the required length. On the Samsung Knox for Android device: 1. Open the device settings. 2. Select "Lock screen". 3. Select "Screen lock". 4. Enter current password. 5. Select Password. 6. Attempt to enter a password with fewer characters than the required length. 7. Verify the password is not accepted. If the configured value of the "Min Length" setting is less than the required length or if device accepts a password of less than the required length, this is a finding. (**) When device encryption is enabled, Samsung Knox for Android automatically enforces a minimum length 6.
Configure the MOS to enforce a minimum password length of 6 characters. On the MDM Administration Console, set the "Min Length" value to 6 or greater in the "Android Password Restrictions" rule. (**) When device encryption is enabled (always enabled by the DoD configuration), Samsung Knox for Android automatically enforces a minimum length 6.
