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 complete 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

Review the configuration to determine if the Samsung Android devices' Work Environment is enforcing a minimum password length of six characters. This validation procedure is performed on both the management tool and the Samsung Android device. On the management tool, in the Work Environment password policies, verify "minimum password length" is set to "6". On the Samsung Android device, confirm if the user has "One Lock" enabled (Settings >> Security and privacy >> More security settings >> Work profile security >> Use one lock). If "One Lock" is enabled: 1. Open Settings >> Lock screen >> Screen lock type. 2. Enter current password. 3. Tap "PIN". 4. Verify the text "PIN must contain at least", followed by a value of at least "6 digits", appears above the PIN entry. If "One Lock" is disabled: 1. Open Settings >> Security and privacy >> More security settings >> Work profile security >> Work profile lock type. 2. Enter current password. 3. Tap "PIN". 4. Verify the text "PIN must contain at least", followed by a value of at least "6 digits", appears above the PIN entry. If on the management tool "minimum password length" is not set to "6", or on the Samsung Android device the text "PIN must contain at least" is followed by a value of less than "6 digits", this is a finding.
