Final answer:
National insider threat policies apply to government bodies and organizations handling national security information, involving measures to identify risks from insiders and safeguard sensitive data, guided by statutes such as the National Security Act and the Patriot Act.
Step-by-step explanation:
National insider threat policies pertain to measures within governmental bodies and affiliated organizations designed to identify and mitigate risks posed by individuals who have authorized access to sensitive information, facilities, or systems and may use that access to harm national security. Such policies are applicable across various departments and agencies that are part of a nation's government, encompassing the intelligence and counterintelligence communities, defense establishments, and any other sectors that deal with national security information. These policies enact safeguards guided by numerous statutes, such as the National Security Act, the Patriot Act, the Homeland Security Act, and more. They ensure that intelligence and counterintelligence services work efficiently to both protect the nation from internal threats and to defeat external threats.
Using intelligence services to defeat threats involves the collection, analysis, and dissemination of information regarding foreign entities that may pose risks. Conversely, using counterintelligence services to protect against internal threats includes identifying and neutralizing espionage, sabotage, or other activities conducted by insiders who may have malicious intent. The implementation of these policies includes ongoing vetting, training, and awareness programs, employing an insider-outsider model to ensure that individuals within the organization (insiders) are consistently scrutinized and that the information they handle is carefully controlled.
