personnel device software install/upgrade (Information Flow): This flow supports installation and update of software residing in Personnel Devices. It supports download of the software installation files, including executable code and associated support files.

Center (Source Physical Object): This general physical object is used to model core capabilities that are common to any center.

Personnel Device (Destination Physical Object): 'Personnel Device' represents devices used by emergency personnel or maintenance and construction personnel in the field. In the case of emergency personnel, the devices would include body cameras or smartphones (and their peripherals) that can be used by emergency personnel to provide images or video as well as send or receive data regarding the incident. The devices could also be used for incident scene safety messages to the personnel. In the case of maintenance and construction field personnel, the devices could be cellular phones or specialized safety devices that would be used for work zone safety messages to the personnel.

Proprietary Data - Proprietary Comm (16)
(None-Data) - Secure Wireless Internet (EU) (32)

Solutions are sorted in ascending Gap Severity order. The Gap Severity is the parenthetical number at the end of the solution.

Selected Solution

TUF - Secure Wireless Internet (ITS)

Solution Description

This solution is used within the U.S.. It combines standards associated with TUF with those for I-M: Secure Wireless Internet (ITS). The TUF standards include upper-layer standards required to install and update application software. The I-M: Secure Wireless Internet (ITS) standards include lower-layer standards that support secure communications between two entities, either or both of which may be mobile devices, but they must be stationary or only moving within wireless range of a single wireless access point (e.g., a parked car). Security is based on X.509 or IEEE 1609.2 certificates. A non-mobile (if any) endpoint may connect to the service provider using any Internet connection method.

Security

Information Flow Security
	Confidentiality	Integrity	Availability
Rating	High	High	Moderate
Basis	PID control, configuration and software/firmware update should all be protected from view. A hostile third party could use this information to reverse engineer control/configuration/update processes, and use that information in an attack across a broad swatch of similar devices, which would have severe effects to the installed base.	PID control, configuration and update need to be correct or the PID may be misconfigured, which for some applications could have severe safety impacts.	PID control, configuration and update needs to be available; however the availability requirement is probably less than Integrity, as without this flow the PID can continue to operate. The exception would be post-cyber attack, when this flow becomes critical.
