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
