SCADA Security

Derived from Iotellect, Iotellect SCADA/HMI inherits its powerful and flexible role-based security model. System operators have separate user accounts. These accounts may own resources (controller accounts, HMIs (dashboards), alerts, reports, event filters). However, the system allow to share resource view/edit permissions between different accounts. See Security and Permissions for more information.

HMI Security

Some SCADA systems associate permission levels and checks with every component of HMI interfaces. Iotellect SCADA/HMI uses a smarter method of controlling what a certain HMI (dashboard) can and cannot do:

  • Dashboard components have no security-related information associated with them

  • The working dashboard inherits the permissions of the user who launched it

  • Every read or write request to the server data model uses the same effective permission level (i.e. permissions of the user that started the HMI dashboard)

  • Permissions are checked on the server side, therefore compromising security by "hacking" the client-side dashboard is not possible

  • Fine-grained permission control is performed by giving system operators different levels of access to different system resources and devices
