Description
Password strength is a measure of the effectiveness of a password in resisting guessing and brute force attacks. Passwords that contain repeating or sequential characters are significantly easier to guess than those that do not contain repeating or sequential characters. Therefore, disallowing repeating or sequential characters increases password strength and decreases risk. SFR ID: FMT_SMF_EXT.1.1 #01b

Check Text ( C-70143r1_chk )
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 "Max Sequential Characters" and "Max Sequential Numbers" settings in the "Android KNOX Container >> Container Password Restrictions" rule. 2. Verify the value of the setting is the same or less than the required length. On the Samsung KNOX for Android device: 1. Open the KNOX Container. 2. Select "KNOX Settings". 3. Select "Lock type. 4. Enter current password. 5. Select "Password". 6. Attempt to enter a password that contains sequential characters or sequential numbers of length greater than the required length. 7. Verify the password is not accepted. If the configured values of the "Max Sequential Character" and "Max Sequential Number" settings are greater than the required length, or if the device accepts a password that contains sequential characters or sequential numbers of length greater than the required length, this is a finding.

Fix Text (F-75905r1_fix)
Configure the mobile device to enforce a password that does not contain more than two sequential or repeating characters or numbers. On the MDM Administration Console, set the "Max Sequential Characters" and "Max Sequential Numbers" values to "2" in the "Android KNOX Container >> Container Password Restrictions" rule.
