Design Basis Threat
Information about the spectrum of potential adversaries can be ascertained through a variety of sources, including national or local intelligence, law enforcement, news reports, and government directives. The type of information needed includes, but is not limited to, a group's motivation, size, capabilities, financial resources, technical skills, weapons, equipment, and tactics. Once this information has been collected, it is organized and condensed into a representative set of attributes and characteristics for adversaries. This process is completed by the competent authority, which is the entity with the legal or invested responsibility of ensuring that facilities are sufficiently protected against potential adversaries.
The Design Basis Threat (DBT) is the condensed threat that the operator of a facility will receive from the competent authority. The DBT is the maximum credible threat that the PPS must be designed to defeat. It is used to establish objectives and requirements of the PPS and is the criteria against which the PPS will be evaluated.
