Controller Security
Micro800 security generally has two components:
•
Exclusive Access
which prevents simultaneous configuration of the
controller by two users
•
Controller Password Protection
which secures the Intellectual Property
contained within the controller and prevents unauthorized access
Exclusive Access
Exclusive access is enforced on the Micro800 controller regardless of whether the
controller is password-protected or not. This means that only one Connected
Components Workbench session is authorized at one time and only an
authorized client has exclusive access to the controller application. This ensures
that only one software session has exclusive access to the Micro800
application-specific configuration.
Exclusive access is enforced on Micro800 firmware revision 1 and 2. When a
Connected Components Workbench user connects to a Micro800 controller, the
controller is given exclusive access to that controller.
Password Protection
By setting a password on the controller, a user effectively restricts access to the
programming software connections to the controller to software sessions that can
supply the correct password. Essentially, Connected Components Workbench
operation such as upload and download are prevented if the controller is secured
with a password and the correct password is not provided.
Micro800 controllers with firmware revision 2 and later are shipped with no
password but a password can be set through the Connected Components
Workbench software (revision 2 or later).
In Connected Components Workbench software revision 10 or later, a stronger
password algorithm is introduced to provide better security. To take full
advantage of this enhancement, the Micro800 controller must have firmware
revision 10 or later, and the project must also be version 10 or later.
The controller password is also backed up to the memory backup module (that is,
2080-MEMBAK-RTC2 for Micro830, Micro850 and Micro870;
2080-MEMBAK-RTC for Micro830 and Micro850; 2080-LCD for Micro810;
and microSD card for Micro820 controllers).
