Discussion

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

Review the configuration to determine if the Samsung Android devices are disallowing passwords containing more than four repeating or sequential characters.

This validation procedure is performed on both the management tool and the Samsung Android device.

On the management tool, in the device password policies, verify "minimum password quality" is set to "Numeric(Complex)" or better.

On the Samsung Android device: 
1. Open Settings >> Lock screen >> Screen lock type. 
2. Authenticate using current method. 
3. Tap "PIN". 
4. Verify that PINs with more than four repeating or sequential numbers are not accepted.

If on the management tool "minimum password quality" is not set to "Numeric(Complex)" or better, or on the Samsung Android device a password with more than four repeating or sequential numbers is accepted, this is a finding.
