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 #1b

Not Applicable for the COBO use case. Review Samsung Android 7 with Knox configuration settings to determine if the mobile device is prohibiting container passwords with more than two repeating or sequential characters. If feasible, use a spare device to try to create a password with more than two repeating or sequential characters (e.g., bbb, 888, hij, 654). This validation procedure is performed on both the MDM Administration Console and the Samsung Android 7 with Knox device. On the MDM console, do the following: 1. Ask the MDM administrator to display the "Maximum Sequential Characters" setting in the "Android Knox Container >> Container Password Restrictions" rule. 2. Verify the value of the setting is set to two or less sequential characters. 3. Ask the MDM administrator to display the "Maximum Sequential Numbers" setting in the "Android Knox Container >> Container Password Restrictions" rule. 4. Verify the value of the setting is set to two or less sequential numbers. On the Samsung Android 7 with Knox device, do the following: 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 more than two sequential characters or sequential numbers. 7. Verify the password is not accepted. If the MDM console "Maximum Sequential Character" and "Maximum Sequential Number" are set to more than two repeating or sequential characters for the Knox container or on the Samsung Android 7 with Knox device, a password with more than two repeating or sequential characters is accepted for the Knox container, this is a finding.
