In a security context, the term "cordon" refers to a barrier that restricts movement and access to certain areas. It serves as a protective measure to control the flow of people or vehicles, often established during security incidents, emergencies, or special events to ensure safety and maintain order. The implementation of a cordon is crucial for limiting entry to sensitive zones, ensuring that unauthorized individuals cannot access potentially dangerous or secure locations. This tactic is commonly used by law enforcement and security personnel to create a safe perimeter around an area that needs to be isolated for various reasons, such as crowd control, investigation, or confinement of hazardous situations. Thus, understanding the role of a "cordon" is essential for recognizing its function in security operations.
