Setting Description
Lock Port after Specifies the number of failed login attempts allowed before
Failed Logins the system locks a remote access login port from accepting
logins. If set to Off, the system does not lock remote access
login ports due to failed login attempts.
Port Lock Duration Specifies the amount of time that a remote access login port
in Minutes remains locked due to failed login attempts.
The following is an example of how the port lockout feature works.
An HDX system is configured with these settings:
• System > Admin Settings > General Settings > Security > External
Authentication is disabled.
• System > Admin Settings > General Settings > Security > Security
Settings > Require Login for System Access is enabled.
• System > Admin Settings > General Settings > Security > Remote
Access Settings > Lock Port after Failed Logins is set to 3.
• System > Admin Settings > General Settings > Security > Account
Management > Admin Account > Lock Account after Failed Logins is set
to 5.
A user fails to log in to the Admin account twice on the web interface, and at
the same time another user has also failed twice to log in to the Admin account
on the local interface. If the next attempt to log in to the Admin account on the
web interface is unsuccessful, the web interface is locked to further logins until
the expiration of the Port Lock Duration in Minutes period. However, the
user on the local interface still has three more attempts to successfully login
before the local interface locks. As this example illustrates, the failed login
attempts made to a port are specific to that port and do not accumulate across
other login ports. Each port has its own counter.
