D.2.1 - Border and transportation security
Border and Transportation Security includes facilitating or deterring entry and exit of people, goods, and conveyances at and between U.S.
ports of entry, as well as ensuring the security of transportation and infrastructure networks, facilities, vehicles, and personnel within the United States. Border control involves enforcing the laws regulating the admission of foreign-born persons (i.e., aliens) to the United States. This includes patrolling and monitoring borders and deportation of illegal aliens. Some border control information is also associated with other mission information types (e.g., criminal apprehension, and criminal investigation and surveillance information). In such cases, the impact levels of the associated mission information may determine impact levels associated with border control information. Some aspects of ensuring security of transportation and infrastructure networks, facilities, vehicles, and personnel within the United States are also covered under the information types associated with the transportation mission. In some cases the border control information may be classified. Any classified information is treated under separate rules established for national security information. The recommended categorization for unclassified border and transportation security information follows:
Security category
Confidentiality Moderate
The confidentiality impact level is the effect of unauthorized disclosure of border control information on the ability of responsible agencies to enforce laws regulating the admission of foreign-born persons (i.e., aliens) to the United States. Generally, the effects of unauthorized disclosure of border control information are usually confined to a single geographic region, immigration case, or deportation case. Even so, unauthorized disclosure may have a serious adverse effect on mission functions, cause significant degradation in mission capability, or place the agency at a significant disadvantage with respect to its border control responsibilities. Particularly in the case of immigration, naturalization, and deportation activities, unauthorized disclosure of information can violate privacy policies. Such unauthorized disclosures can have a serious effect on public confidence in the agency. Special Factors Affecting Confidentiality Impact Determination: Where border control information is also associated with other mission information types (e.g., criminal apprehension, and criminal investigation and surveillance information), the confidentiality impact level associated with the information may be high. Where unauthorized disclosure of border control information may put the physical safety of personnel into serious jeopardy, the confidentiality impact level associated with the information may be high. Unauthorized disclosure of confidentiality of information associated with ensuring security of transportation and infrastructure networks, facilities, vehicles, and personnel within the United States can result in facilitation of terrorist activities that endanger human life. In some cases, the consequent threat to critical infrastructures, key national assets, and human life can be catastrophic. Consequently, the confidentiality impact level associated with information associated with ensuring security of transportation and infrastructure networks, facilities, vehicles, and personnel within the United States is normally high. Recommended Confidentiality Impact Level: The provisional confidentiality impact level recommended for most border control information is moderate.
Integrity Moderate
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. Unauthorized modification or destruction of information affecting external communications (e.g., web pages, electronic mail) may adversely affect operations or public confidence in the agency, but the damage to the mission would usually be limited. The consequences of unauthorized modification or destruction of information can be very serious if the information is critical to tactical operations. Special Factors Affecting Integrity Impact Determination: Unauthorized modification or destruction of information associated with ensuring security of transportation and infrastructure networks, facilities, vehicles, and personnel within the United States may seriously affect mission operations or result in the loss of human life. Unauthorized modification or destruction of information affecting anti-terrorism information may adversely affect mission operations in a manner that results in unacceptable damage to critical infrastructures and/or key national assets or loss of key national assets and/or human life. Consequently, the integrity impact level associated with information that ensures the security of transportation and infrastructure networks, facilities, vehicles, and personnel within the United States is high. Recommended Integrity Impact Level: The provisional integrity impact level recommended for border control information is moderate.
Availability Moderate
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 border control information. Functions and processes supported by most border control information are not time-critical. Also, disruption of access will have only a limited adverse effect on agency operations (including mission functions and public confidence in the agency), agency assets, or individuals. Special Factors Affecting Availability Impact Determination: There may be time critical cases, for example, information regarding transport of illegal aliens or information about a physical threat posed by aliens that border control personnel have been assigned to interdict. In such cased, the availability impact will be high. The consequences of disruption of access to information or information systems associated with ensuring security of transportation and infrastructure networks, facilities, vehicles, and personnel within the United States may be severe. Also, anti-terrorism missions are not reliably tolerant of delays. The availability impact level for information systems that ensure the security of transportation and infrastructure networks, facilities, vehicles, and personnel within the United States is high. Recommended Availability Impact Level: Except for such time-critical cases, cases where impact is driven by information shared with associated missions (e.g., anti-terrorism), the provisional availability impact level recommended for border control information is normally moderate.
