  • 5. DETENTION INDUSTRYCONSIDERATIONS 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
  • 6. 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
  • 7. 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
  • 8. USER GROUP CONFIGURATION
  • 9. 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
  • 10. SYMBOL LEVEL SECURITY Position Properties Command Disable Field User / Group Level Checks
  • 11. 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
  • 12. DOOR CONTROL ARCHITECTURE Database back end  Used for loading / storing device parameters  Provides flexibility (device names, etc.)  Retentive tags allow offline operation
  • 13. 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
