ClearSCADA security helps to protect the SCADA system from unauthorized access. System access requires a password. The actions that you perform as a user are logged by the system (see Events).
As a system user, you will be assigned access permissions according to the functions you need to perform, and you will only be able to see the functions that this makes available to you.
You will use a ViewX or WebX client that has been configured by a higher level user, which will provide access to the displays and features that you need to carry out your tasks, such as performing actions on database items and managing alarms.
System security allows you to:
- Log On to ViewX
- Log Off from ViewX
- Change your Password via ViewX.
(You can only change your password in ClearSCADA if your user account is managed directly in ClearSCADA and you have sufficient permissions to change your own password. If your user account is associated with a Windows User Profile, password changes are managed via the relevant Windows domain.)
When you log off from ViewX, the current settings for the following interface components are stored locally as a client setting and associated with your user account:
- Tool Windows
- Alarm Banner (see Alarm Banner in the ClearSCADA Guide to Alarms)
- ViewX ribbon
- Quick Access Toolbar
- Recent Documents (see File Menu).
These settings are then restored when you log on to the same computer. If no one is logged on, the most recent settings for the Guest user account are displayed.
