What are the key terminal security measures?

• A. Visible Law Enforcement
• B. Airport signage and announcements
• C. Random screening of passengers
• D. K-9 patrols

Answer: (A)

Visible law enforcement serves as the primary terminal security measure because the presence of uniformed officers and security personnel creates a strong deterrent and enables immediate response to incidents. This ongoing visibility signals that security is active, helps identify suspicious behavior early, and allows rapid coordination with cameras, access controls, and other layers to contain threats, manage crowds, and evacuate if needed. Other measures like signage and announcements support safety by informing passengers, but they don’t deter or detect threats in real time. Random screening adds another layer but requires substantial resources and isn’t as universally preventive as a constant security presence. K-9 patrols provide valuable supplemental capability for certain threats, but they’re not the overarching measure that establishes ongoing terminal security.
