The LG Android 5.0 platform must be configured to prohibit more than 10 consecutive failed authentication attempts.

Overview

Description
Users must not be able to override the system policy on the maximum number of consecutive failed authentication attempts because this could allow them to raise the maximum, thus giving adversaries more chances to guess/brute-force passwords, which increases the risk of the mobile device being compromised. Therefore, only administrators should have the authority to set consecutive failed authentication attempt policies. SFR ID: FMT_SMF.1.1 #02

Check Text ( C-59617r1_chk )
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 "Maximum failed password attempts" setting in the MDM console. 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. 1. Enter the wrong Password until the device performs a factory reset. 2. Note the number of password attempts needed before the device performs a factory reset. If the "Maximum failed password attempts" is not set to 10 or less or the device did not perform a factory reset before a wrong password was entered eleven times, this is a finding.
