Which law addresses interagency sharing of foreign intelligence or counterintelligence information between law enforcement and intelligence/national-security personnel?

• A. FISMA
• B. E-Verify
• C. Section 203 of the Patriot Act
• D. CIIA

Answer: (C)

Interagency sharing of foreign intelligence or counterintelligence information is driven by a need to break down silos between law enforcement and national-security entities so they can collaborate effectively to prevent threats. The provision that directly enables this kind of sharing is Section 203 of the Patriot Act, which authorizes and outlines how information obtained in criminal investigations and intelligence work can be shared across agencies to improve detection and prevention of terrorist activities. This makes it the best choice for addressing how such information is exchanged. By contrast, FISMA focuses on securing federal information systems, E-Verify concerns employment eligibility verification, and while a Counterintelligence Information Act relates to counterintelligence matters, it does not establish the explicit cross-agency sharing framework that Section 203 provides.
