SCADA System Security
The HT3 SCADA Software program is password protected to prevent unauthorized access to the system. A valid user account login and password are required to access the system. All passwords are MD5 encrypted for optimum security protection.
The login parameters let the system administrator specify a user's capabilities when assigning the user a login name and password.
Once logged in, actions within HT3 are limited by the permissions assigned to that particular login account. With this level of security, access to system functions and operator displays can be limited, or restricted altogether. The screenshot and definitions, below, describe the different levels of permissions.
When logging in, you can also choose the type of audio that you want to hear at the workstation when an alarm occurs: voice alarm messages; a beep instead of a voice alarm message; or no sound at all (uncheck both the Enable Audio and the Beep Only options).
User Settings and Permissions:
- Printer - Printer to which this user's reports will be sent.
- Partition - Partition to which this user belongs. Partitions are logical divisions of telemetry information. Partitioning allows RTUs in a telemetry system to be configured in any one of four separate partitions; one telemetry system can be shared by four different departments (for example, Wastewater Collections, Reclaimed Water Distribution, Water Treatment Plant, and Storm Water Control). When an operator is given permission to access a particular partition and logs in to the system, they are blocked from accessing the telemetry components of the other partitions. This feature makes it appear as if the system only serves the segment that the operator has accessed. Since all four partitions can use the same Hyper SCADA Server, software, networks, radio frequencies, CTUs, RTUs, etc., the cost-effectiveness of this feature becomes a valuable asset.
- Skin ID - This option, which is part of the legacy HyperTAC II software, is not supported in this release of HT3.
The first three permission settings, Control, Acknowledge Alarms, and Shutdown System have two states to select from - enabled or disabled.
- Control - Allows manual control of control points.
- Acknowledge Alarms - Allows alarm acknowledgment.
- Shutdown System - Allows system shutdown (stop and start telemetry), rebooting of the Hyper Server Module (HSM), backup battery testing for the Hyper SCADA Server (HSS), and HSS hardware resetting.
The remaining settings have an additional option - View - that allows a user to view the information but prevents them from taking any action. For example, selecting View for Configure Telemetry would allow a user to view all of the telemetry configurations, but wouldn't allow them to credit, edit, or delete any of the components.
- Configure Users - Allows creation and editing of user accounts.
- Configure Telemetry - Allows addition, deletion, and editing of partitions, keywords, drivers, stations, modules, points, alarms, and auto controls.
- Configure Ladder Logic - Allows the creation of virtual processes via Virtual Logic Builder.
- Configure Scheduled Controls - Allows the creation of scheduled controls, events that automatically occur on certain scheduled days and/or times.
- Configure Screens - Allows the creation of custom screens via Screen Builder.
- Configure Voice - Allows recording of voice alarms.
