What are structural barriers used for security purposes called?

The term 'walls' accurately describes structural barriers used for security purposes because they are solid structures that provide a robust form of protection and obstruction. Walls can serve various functions including preventing unauthorized access, securing perimeters, and providing a physical barrier that enhances security. They are typically built from durable materials and designed to withstand various threats, making them more effective in safeguarding spaces compared to other types of barriers.

While options like fences and partitions may also be used for security, they usually serve different primary purposes. Fences are often more about delineating space and may not provide the same level of security as solid walls. Partitions, on the other hand, are generally used to divide interior spaces rather than to secure perimeters or provide comprehensive security solutions. Thus, walls clearly represent the most suitable choice for structural barriers aimed at enhancing security.
