Notes on Data and System Security

Introduction
System security when using WinCC can be increased by implementing simple measures.
You can find additional information in the WinCC Release Notes under "Notes on Operation
> Windows Operating System"
Preventing Access to the Operating System Layer in Runtime
If the Windows Selection dialog is opened in an activated WinCC project, access to the
Windows operating system is possible using this function. A Windows Selection dialog is
opened, for example, when data is imported or files are selected.
Protect the corresponding function by executing a Permission Check via the User Administrator
to prevent unauthorized access to the operating system.
Preventing access to the Windows toolbar
You can use the computer properties to prevent the Windows taskbar from being displayed in
Runtime. Open the "Parameters" tab in the "Computer properties" dialog and deactivate all
the shortcut keys in the "Disable Keys" area.
