Description
The more attempts an adversary has to guess a password, the more likely the adversary will enter the correct password and gain access to resources on the device. Setting a limit on the number of attempts mitigates this risk. Setting the limit at 10 gives authorized users the ability to make a few mistakes when entering the password but still provides adequate protection against dictionary or brute force attacks on the password.

Check Text ( C-67463r2_chk )
This validation procedure is performed on both the MDM Administration Console and the LG Android device. On the MDM Console, do the following: 1. Ask the MDM administrator to display "Maximum failed password attempts" in the password policy. 2. Verify the value is 10 or less. On the LG Android device: Note: It is recommended that this procedure be performed only on a test device. Enter the wrong Password until the device performs a factory reset. Note: The number of password attempts needed before the device performs a factory reset. If on the MDM console the "Maximum failed password attempts" is not set to 10 or less or the LG Android device did not perform a factory reset before a wrong password was entered eleven times, this is a finding.
