Vulnerability discussion

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.SFR ID: FMT_SMF.1.1 #01

Check content

This validation procedure is performed on both the MDM Administration Console and the LG Android device. Check whether the appropriate setting is configured on the MDM Administration Console: 1. Ask the MDM administrator to display the "Password length" setting in the MDM console. 2. Verify the setting for the password length equals or is greater than the required length. On The LG Android device: 1. Unlock the device 2. Navigate to the password entry screen: Settings >> Lockscreen >> Select screen lock >> Password 3. Attempt to enter a password with a length less than the required value. If the configured value of the "Password length" setting is less than the required length, or if device accepts a password of less than the required length, this is a finding.
