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.

Access Control Plug-in Project Integration

The AccessControlPlugin is a shared library with a user-defined name. To use the library inside of your project, add the entry:

accessControlPlugin =<AccessControlPluginFilename>

to the [general] section of the config file. If you omit the shared library extension, the configuration is OS independent. When loading the shared library on WINDOWS, the extension “.dll” and on UNIX the extension “.so” is automatically appended to the given name.

Note:

Note that the name accessControlPlugin above is just an example. You can use a customized name for your accessControlPlugin.

For more information see the Config entry description for accessControlPlugin or the WinCC OA implementation of the Access Control Plug-in.
