In order to participate in this service package, each information flow triple should meet or exceed the following security levels.

Information Flow Security
Source Destination Information Flow Confidentiality Integrity Availability
Basis Basis Basis
Center Center Personnel center operator data High High High
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 center is not directly in front of the Center 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. Backoffice operations flows should generally be correct and available as these are the primary interface between operators and system. Backoffice operations flows should generally be correct and available as these are the primary interface between operators and system.
Center Service Monitor System center status High High High
System operational status information could be used to either initiate or confirm attacks, leading to significant downtime of related C-ITS systems. System status information needs the greatest possible correctness, as if it is incorrect then inappropriate actions may be triggered that, for large backoffice and core systems, have widespread repurcussions. Monitoring of system operational status has the highest possible needs for availability, as without an understanding of system state it is difficult to impossible to manage the system.
Center Support Maintenance Equipment center equipment status Moderate Moderate Moderate
The operational state of center systems, if known to an attacker or individual with criminal intent, could be used to facilitate the commission of a crime. Individual centers may be more or less important in this context; for example knowing whether a traffic management center is operating is probably more relevant to the criminal than knowing if a weather information center 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.
Center Support Maintenance Equipment service 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, systems may not be repaired on time, resulting in inefficient use of maintenance assets and higher overall downtime. If this data is incorrect or unavailable then maintenance assets may not be appropriately assigned, systems may not be repaired on time, resulting in inefficient use of maintenance assets and higher overall downtime.

Backoffice operations flows should generally be correct and available as these are the primary interface between operators and system.
Service Monitor System Center center fault data Moderate Moderate Moderate
Device status information should not be viewable by third parties, as those with criminal intent may use this information toward their own ends. If incorrect or changed, could lead to inappropriate maintenance activity, which has a significant cost in itself and contributes negatively to system operational status. Scope is small, but impact significant if this occurs with many instances. A delay in reporting this may cause a delay in necessary maintenance. Considered higher availability requirement than the source flow (RSE status) because this information aggregates many instances of the source.
Support Maintenance Equipment Center center equipment commands Moderate High High
Commands could be sensitive and should include authentication data, thus should be MODERATE. Commands to Centers 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 center may be mis-configured or compromised. Considered HIGH as opposed to MODERATE because the operational scope of a Center is typically quite large compared to a Field device. Without the ability to locally diagnose, operate, update and configure Center Equipment, the equipment is effectively out of control and would have to be taken out of service.
Support Maintenance Equipment Center center equipment configuration settings Moderate High High
Commands could be sensitive and should include authentication data, thus should be MODERATE. Center system control, configuration and update need to be correct or the center may be misconfigured, which for some applications could have severe safety impacts. If the center has no safety-related functions, or little impact on regional mobility, this could be MODERATE. Without the ability to locally diagnose, operate, update and configure Center system Equipment, the Center is effectively out of control and would have to be taken out of service.
Support Maintenance Equipment Center center equipment software install/upgrade Moderate High Moderate
Equipment software is sensitive and should include authentication data, thus should be MODERATE. Software updates to Center components 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. The ability to remotely update and configure software 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.
Support Maintenance Equipment Center service maintenance status 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, systems may not be repaired on time, resulting in inefficient use of maintenance assets and higher overall downtime. If this data is incorrect or unavailable then maintenance assets may not be appropriately assigned, systems may not be repaired on time, resulting in inefficient use of maintenance assets and higher overall downtime.
Support Maintenance Equipment Support Maintenance Personnel support equipment status presentation Moderate Moderate High
System maintenance flows should have some protection from casual viewing, as otherwise imposters could gain illicit control over field equipment 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.
Support Maintenance Personnel Support Maintenance Equipment support personnel equipment input Moderate Moderate High
System support flows should have some protection from casual viewing, as otherwise imposters could gain illicit control over support equipment or the equipment managed by the support equipment. System support flows are the primary interface between support personnel and support equipment, and must present accurate data or inappropriate support actions may be taken.
