Center --> Field:
field equipment configuration settings
Definitions
field equipment configuration settings (Information Flow): Control settings and parameters that are used to configure field equipment.
Center (Source Physical Object): This general physical object is used to model core capabilities that are common to any center.
Field (Destination Physical Object): This general physical object is used to model core capabilities that are common to any piece of field equipment.

Interoperability | Description |
---|---|
Local | In cases where an interface is normally encapsulated by a single stakeholder, interoperability is still desirable, but the motive is vendor independence and the efficiencies and choices that an open standards-based interface provides. |

Basis | Commands could be sensitive; monitoring of center-based control could enable an attacker's situational awareness, thus should be MODERATE. | Commands to Field Equipment must be authenticated as having come from a source entitled to issue that command, or roadway equipment may be comprimised. Similarly, commands and configuration must be guaranteed to be correct; not manipulated midstream or corrupted, or the roadway equipment may be mis-configured or compromised. | The ability to remotely diagnose and configure devices is inherent to their successful operation. If this link is down it either suggests or will prompt field maintenance activity, which has a non-trivial cost and resource impact. |
