By limiting the number of failed logon attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute-forcing, is reduced.
This should not be configured in Device >> Setup >> Management >> Authentication Settings; instead, an authentication profile should be configured with lockout settings of three failed attempts and a lockout time of zero minutes.
Go to Device >> Authentication Profile
Select the configured authentication profile or select 'Add' (in the bottom-left corner of the pane) to create a new one.
In the 'Authentication Profile' field, enter the name of the authentication profile that will be used to control each person's authentication process.
The 'Lockout Time (min)' field is the lockout duration; this must be set to '0'. This will keep the lockout in effect until it is manually unlocked.
In the 'Failed Attempts' field, enter '3'.
Apply the authentication profile to the Administrator accounts.
Go to Device >> Administrators
Select each configured account or select 'Add' (in the bottom-left corner of the pane) to create a new one.
In the 'Authentication Profile' field, enter the configured authentication profile.
This authentication profile should not be applied to the emergency administration account since it has special requirements.
Commit changes by selecting 'Commit' in the upper-right corner of the screen.
Select 'OK' when the confirmation dialog appears.
