User Management
All about authorization, authentication and login-customization.
- User Administration
  The WinCC OA user administration provides important features for controlling users that use the system. Security is an important issue in the automation technology when controlling highly sensitive systems and it is of utmost importance that the users of the system have only access to the specified area of operation. With the WinCC OA user administration, you can administer users so that they can use the resources effectively without inflicting damage to the system inadvertently or otherwise
- Device Management
  The Device Management allows you to define which WinCC OA UI connections (mobile application and Desktop UI) are allowed to connect to your project. Additionally a direct overview over the available licenses and currently connected devices is shown.
- Inactivity/AutoLogout
  The inactivity management in WinCC OA prevents not authorized persons or persons with a wrong identity to use a workplace for forbidden or not traceable operations.
- Access Control Plug-in
  The WinCC OA Access Control Plug-in can be used to control the access to data points (read, write, display) via user rights.
- Authorization Check Plug-in
  The authorization check plug-in allows setting access rights on data point element level (data point values).
- Authentication via Kerberos, basics
  In a more and more networking world, a WinCC OA system could be exposed to different types of attacks. An unauthorized WinCC OA system could connect to the distribution manager or hackers could try to manipulate WinCC OA messages.
- Login Framework
  The WinCC OA login framework provides a framework that is easy to extend. The WinCC OA login panels can be easily replaced by user-specific panels without having to re-implement the functionality.
- System Use Notification
  You can use the system use notification panel to display an instruction to the user when logging into the WinCC OA system. The user must confirm the notification before logging into the WinCC OA project.

Example panel for the Access Control Plug-in

An example panel for the Access Control Plug-in can be found in your WinCC OA installation directory: wincc_oa_path/Panels/Examples/accessControlPlugin/accessControlPluginConfigExample.pnl

To use the example panel, one of the Demo Access Control Plug-ins, which are installed as part of the WinCC OA API installation component, can be used. These plug-ins are:

CNSPlugin
CommonConfigPlugin
GeneralConfigPlugin

Set the accessControlPlugin config entry ([general] section) to one of these Demo Plug-ins mentioned above. The panel then automatically recognizes the selected demo plug-in and behaves accordingly.

The example panel provides two different views: the data point view (for CommonConfigPlugin and GeneralConfigPlugin) and the plant model tree view (for CNSPlugin).

In the panel you can set different permissions for read, write and visibility of data points.

By selecting a data point, the corresponding settings are displayed on the right side of the example panel, see figure below.
