CONSIDERATIONS
Physical Security
General Public
Facility Staff
Inmates
System Stability / Redundancy / Failover Required
Each HMI capable of standalone operation
Prioritized sequence of failover
System activity mainly user driven, not automated/process driven
Emphasis on “human” part of HMI
HMI COMPUTER SECURITY
Physical
InduSoft Hardkeys are secured to the HMI to prevent removal
HMIs secured in locked cabinets
Keyboard / mouse removed on touchscreen based systems
Auto-Run features of the Operating System disabled
HMI COMPUTER SECURITY
InduSoft
Project runs automatically on HMI startup
Security System used to prevent access to the Operating System
Close Project disabled
Task Switch (Alt-Tab) disabled
Task Manager disabled
Security System used to prevent Engineering Access by application users
Auto-Logoff enabled for all groups with Engineering Access
USER GROUP CONFIGURATION
HMI COMPUTER SECURITY
Application
InduSoft startup screen prevents access to the system without a valid logon
Once logged in, navigation is restricted based on HMI station and user
Device icon commands are disabled by default and must be enabled by the
PLC in order for them to operate
Some devices have additional security restrictions (interlocks, exterior
doors, etc.)
Some functions have additional restrictions (Group Release, Emergency
Release, etc.)
HMIs can be remotely disabled in the event of a security breach
SYMBOL LEVEL SECURITY
Position Properties
Command Disable Field
User / Group Level Checks
DOOR CONTROL ARCHITECTURE
Class based
All doors have identical capabilities
Individual door functionality based on the parameters assigned to the class
members
Provides flexibility to modify functionality without modifying code
DOOR CONTROL ARCHITECTURE
Database back end
Used for loading / storing device parameters
Provides flexibility (device names, etc.)
Retentive tags allow offline operation
DOOR CONTROL ARCHITECTURE
Communication
PLC Communication accomplished primarily Standard Driver Sheets
Allows enabling/disabling of individual sheets to optimize efficiency
Scripting
Extensive use of global procedures to centralize code
Extensive use of VBScript within global procedures to enhance built-in
functionality
Graphics
Symbols created for all devices to make modifications easy
Symbols primarily indicate device status only and contain minimal logic
