While time reference should be universally available, time reference coupled with vehicle location is tracking data. This flow is internal to a vehicle, but should probably be encrypted to discourage hacking and snooping on the vehicle bus. Thus MODERATE. Location and time data is the basis for crash imminent safety and a host of other applications. Corruption of this flow could lead directly to a vehicle accident.

Unlikely that this includes any information that could be used against the originator. Status information should be correct, but modification will cause only minor inconvenience. Since this monitors the health and safety of the vehicle and that information is eventually reported to the driver and fleet manager, it should be available at all times as it directly affects vehicle and operator safety.
Center Maint and Constr Management Center equipment maintenance request Moderate Moderate Moderate
Device operational status information should be known only by those entities that need to know for operations and maintenance. Allowing others to read this information may enable abuse of those systems, 3rd party monitoring of system status when that may not be desireable, and reverse engineering of this and similar information flows. If this data is incorrect or unavailable then maintenance assets may not be appropriately assigned, resulting in inefficient use of maintenance assets and higher overall downtime.

The operational state of field devices, if known to an attacker or individual with criminal intent, could be used to facilitate the commission of a crime. Individual devices may be more or less important in this context; for example knowing whether a security camera is operating is probably more relevant to the criminal than knowing if the DMS is operating, though the latter could still be useful info. Instances of this flow that are local minimize this risk however, so for these local flows Confidentiality is considered LOW. If incorrect or changed, could lead to inappropriate maintenance activity, which has a significant cost in itself and contributes negatively to system operational status. This must be timely to support operational uptime requirements. Lack of monitoring will lead to less uptime, which will impact security, mobility and in some cases, safety.

Field Maintenance Equipment Field field equipment commands Low Moderate High
Commands could be sensitive, however this flow is local, meaning the Field Support Equipment is proximate to the ITS Roadway Equipment. Thus the risk of interception should be low. There may also be constraints on this flow that require this information to be transmitted in the clear. Commands to ITS Roadway 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. Without the ability to locally diagnose, operate, update and configure ITS Roadway Equipment, the equipment is effectively out of control and would have to be taken out of service.
Field Maintenance Equipment Field field equipment configuration settings Moderate Moderate Moderate
Configuration settings could be sensitive; if an attacker knows precisely how a device is configured, it may facilitate an attack. Commands to ITS Roadway 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.
Field Maintenance Equipment Field field equipment software install/upgrade Moderate High High
Field equipment software could be sensitive, both from a vulnerability assessment standpoint and because the software itself may be competition-sensitive. Software updates to Roadway Equipment must be authenticated as having come from a source entitled to provide that software, or roadway equipment may be comprimised. Similarly, such software must be guaranteed to being the intent of the originator; not manipulated midstream or corrupted, or the roadway equipment may be mis-configured or compromised.

Direct interactions between personnel and systems in a backoffice environment are effectively protected by physical means, so long as the interaction is in a dedicated facility. If this interaction is virtual (i.e. ,the MCMC is not directly in front of the MCMC Personnel, like in a cloud-based system) then the user's input requires some degree of obfuscation depending on sensitivity of information. Given that this could include information about compromised or ineffectual systems, including security systems, the potential for damage is high. Thus, HIGH.

Linked to the asset inventory, so the same concerns with this flow as that one, namely that when placed in one spot becomes a "one stop shop" for a nefarious person looking for infrastructure targets. Given the narrow focus of this flow it might be LOW, except that it infers information about specific targets. Infrastructure information should be correct or maintenance assets may be inappropriately assigned. While this changes more than other asset flows, the impact should still be minimal.
Maint and Constr Management Center Center equipment maintenance status Moderate Moderate Moderate
Data is not overly sensitive, but is a bulk statement about the status of all field equipment managed by the maintenance center. A hostile actor could use this information in the commission of a crime, for instance by understanding which cameras were not working and thus what areas are not under surveillance. Center-based data exchanges are expected to be correct, and deserving of at leas some error checking. If this data is corrupted, the receiving center will be misinformed as to the state of field equipment maintenance. Depends on the update frequency required. Possibly LOW, depending on the amount of equipment and what this flow is used for at the terminus.

Contents of this flow enable specialized or elevated use of transportation facilities, which if copied could enable misuse of transportation assets. Incorrect data or unvailability will hamper legitimate maintenance, incident management and emergency use, which can have a significant effect. However, alternative means to allow those behaviors should already exist, at least for well marked emergency and safety vehicles, thus MODERATE and not HIGH.

System maintenance flows should have some protection from casual viewing, as otherwise imposters could gain illicit control over field equipment Information presented to backoffice system operators must be consistent or the operator may perform actions that are not appropriate to the real situation. The backoffice system operator should have access to system operation. If this interface is down then control is effectively lost, as without feedback from the system the operator has no way of knowing what is the correct action to take.

Maintenance vehicle dispatch and routing information is predictive of maintenance vehicle location, and should be protected from hostile actors, as they may use this information for target acquisition or selection or damage assessment, for example. Maintenance vehicle dispatch instructions need to be correct and timely so that road maintenance activities are performed when and where they should be. Corruption of this information would cost time and money and may impact mobility.

Control flows, even for seemingly innocent devices, should be kept confidential to minimize attack vectors. While an individual installation may not be particularly impacted by a cyberattack of its sensor network, another installation might be severely impacted, and different installations are likely to use similar methods, so compromising one leads to compromising all. Control flows, even for seemingly innocent devices, should have MODERATE integrity at minimum, just to guarantee that intended control messages are received. Incorrect, corrupted, intercepted and modified control messages can or will result in target field devices not behaving according to operator intent. The severity of this depends on the type of device, which is why some devices are set MODERATE and some HIGH. There should be multiple mechanisms for this information to arrive at the end recipient. If this is the only mechanism, should be raised to MODERATE.

Typically intended for public distribution. While there are many sources of weather information, some guarantee of correctness is justifiable to keep confidence in provided service. In areas with severe weather it may be justifiable to raise this to HIGH. There should be other sources of this data. It does need to be reliable however; weather can change quickly, and depending on the destination and its operational strategies, timely response may be important. In areas with severe weather it may be justifiable to raise this to HIGH.

Typically intended for public distribution. While there are many sources of weather information, some guarantee of correctness is justifiable to keep confidence in provided service. Even for areas with significant weather events that drive maintenance activities, it would be difficult to justify HIGH for this flow. While the repurcussions of inaccurate data may be significant, they are probably not catastrophic. M&MC relies on weather data for planning and decision making, so this flow needs to be reliable. In areas with flash-weather issues, this might be HIGH.
