+# Physical security in ISO 27001
+
+The article (or control) that deals explicitly with identifying secure areas, which are required to be protected, is **Control 7.1, "Physical security perimeters,"**.
+
+This control is categorized under Clause 7, "Physical controls," of ISO/IEC 27002.
+
+The purpose of Control 7.1 is **"To prevent unauthorized physical access, damage and interference to the organization’s information and other associated assets"**.
+
+The guidance for this control explicitly states that:
+
+- **Security perimeters should be defined and used to protect areas** that contain information and other associated assets.
+- The definition, siting, and strength of each perimeter should be **in accordance with the information security requirements related to the assets within the perimeter**.
+- A secure area can be considered a lockable office or several rooms surrounded by a continuous internal physical security barrier.
+
+Following the definition of secure perimeters (7.1), **Control 7.2, "Physical entry,"** then addresses how these secure areas should be protected by appropriate entry controls and access points.
