Which statement best defines Sensitive/Critical Information Systems (SCIS)?

• A. SCIS are systems and components used to process sensitive but unclassified information or, if compromised, could result in a Denial of Service that would adversely affect the national interest of the conduct of federal programs.
• B. SCIS are only used for public information and do not affect national interests.
• C. SCIS must always be classified information.
• D. SCIS are systems that handle only physical security data.

Answer: (A)

Sensitive/Critical Information Systems focus on protecting information and operations where disruption would affect national interests, even if the data isn’t officially classified. The best definition recognizes that data can be sensitive without being classified and that the stakes lie in what could happen if the system is compromised—such as a Denial of Service or other disruption that harms federal programs or national interests. The wording emphasizes both the sensitivity of the information and the potential impact on operations, not merely the classification status of the data. The other statements miss this point by limiting SCIS to public information, requiring classification, or restricting the scope to physical security data, which does not capture the full range of sensitive and critical systems.
