D.11.1 - Ground transportation
Ground Transportation involves the activities related to ensuring the availability of transit and the safe passage of passengers and goods over land.
Water and fuel pipelines are included among ground transportation assets. Note: The protection of ground transportation from deliberate attack is included in the Transportation Security information type under the Homeland Security mission area. The recommended provisional security categorization for the ground transportation information type is as follows:
Security category
Confidentiality Low
The confidentiality impact level is the effect of unauthorized disclosure of ground transportation information on the ability of responsible agencies to ensure the availability of transit and the safe passage of passengers and goods over land. The protection of ground transportation from deliberate attack is included in the Transportation Security information type under the Homeland Security mission area. For most cases, unauthorized disclosure of ground transportation information will have only a limited adverse effect on agency operations, assets, or individuals. Special Factors Affecting Confidentiality Impact Determination: Some regulatory and tariff enforcement functions associated with the safe passage of passengers and goods over land involve relatively sensitive information. These are included in Law Enforcement. Unauthorized disclosure of accident investigation information that has not yet been adequately researched, coordinated, or edited can result in serious economic harm to individuals and to corporations. Loss in public confidence is a further potential consequence. Additionally, some information associated with ground transportation functions is proprietary to corporations or subject to privacy laws (e.g., the Privacy Act of 1974). (The Privacy Act Information provisional impact levels are documented in the Personal Identity and Authentication information type.) In such cases, the confidentiality impact resulting from unauthorized disclosure may be moderate. Some military ground transportation information is national security information and is outside the scope of this guideline. Recommended Confidentiality Impact Level: The provisional confidentiality impact level recommended for ground transportation information is low.
Integrity Low
The integrity impact level is based on the specific mission and the data supporting that mission, not on the time required to detect the modification or destruction of information. In most cases, the adverse effects of unauthorized modification or destruction of ground transportation information on agency mission functions and public confidence in the agency will be limited. Special Factors Affecting Integrity Impact Determination: Some ground transportation functions are time-critical (e.g., track switching functions associated with rail travel). Unauthorized modification or destruction of time-critical information necessary to these functions can result in large-scale property loss and in loss of human lives. Such information will have a high integrity impact level. Recommended Integrity Impact Level: The provisional integrity impact level recommended for ground transportation information is low.
Availability Low
The availability impact level is based on the specific mission and the data supporting that mission, not on the time required to re-establish access to ground transportation information. Most ground transportation processes are tolerant of reasonable delays. In most cases, disruption of access to ground transportation information can be expected to have only a limited adverse effect on agency operations, agency assets, or individuals. Special Factors Affecting Availability Impact Determination: Some ground transportation functions are time-critical (e.g., track switching functions associated with rail travel). Loss of availability of time-critical information necessary to these functions can result in large-scale property loss and in loss of human lives. Such information will have a high integrity impact level. Recommended Availability Impact Level: The provisional availability impact level recommended for ground transportation information is low.
