Which zones are used at an Entry Control Point (ECP)?

• A. Assessment, Warning
• B. Access, Control
• C. Assessment, Warning, Threat
• D. Detection, Delay, Denial

Answer: (C)

When thinking about an Entry Control Point, you want a progression that handles people from initial observation to decisive action if needed. The three zones used at an ECP are Assessment, Warning, and Threat. The Assessment zone is where screening happens—guards observe credentials, verify purpose, and look for suspicious behavior to decide whether someone can proceed. Next, the Warning zone is for signaling requirements and deterring access—clear indicators, barriers, and cues that help people understand what’s expected and what will happen if they don’t comply. Finally, the Threat zone is where a credible risk is addressed—if a threat is detected, procedures trigger denial of entry or escalation according to policy. Other options don’t fit because they either omit a zone (only Assessment and Warning), refer to generic terms rather than specific ECP zones, or describe a broader security model (detection, delay, denial) that isn’t the zoning framework used at an ECP.
