Make sure that workstations are physically housed in secure locations.
Emerson offers the following recommendations for DeltaV workstations:
- The ProfessionalPLUS
workstation is a mission-critical machine. Make sure it is located in an
extremely secure location to avoid physical tampering.
- Make sure the Application
Station is located in a heightened-security area. However, if it must be
located in the engineer’s workspace, take precautionary measures to prevent
unauthorized physical access to this workstation.
- Physically isolate the
Operator Station CPU from the operator working on it so that it cannot be
booted with custom media but can still be reset in the event of a system crash.
- Use the DeltaVScreenSaver
for multi-user operator workstations to make sure that the workstation is
locked when the user leaves it and to prevent operators from locking out other
operators.
