• A. National Security Special Event
• B. National Special Security Event
• C. National Special Security Emergency
• D. National Strategic Security Event

Answer: (B)

NSSE stands for National Special Security Event, a designation used in U.S. security planning for major events with potential risk to public safety. When an event is designated as NSSE, federal, state, and local authorities (often with the private sector) coordinate to implement a comprehensive security plan. This includes enhanced protective measures, risk assessment, specialized security operations centers, unified command structures, and interoperable communications to ensure rapid response and coordination across agencies. The purpose is to manage and mitigate risks associated with high-profile events, such as presidential inaugurations, major international summits, or other events with large crowds and potential threats. The other wordings don’t reflect the actual term used in security planning, whereas NSSE is the established designation for these high-security events.
