Security of the program, the subsystem "Security"
OpenSCADA is a ramified program that consists of a dozen subsystems and can include many modules. Therefore, giving everyone unlimited access to these resources is reckless, to say the least. In order to differentiate access, OpenSCADA provides the subsystem "Security" whose main functions are:
- storing user accounts and user groups;
- authentication of users;
- verifying access rights to a particular resource.
