+
+## Chapter 8: Security Perimeter
+
+- Goal: prevent escape and contraband passage
+
+### Ingredients of Security
+
+- Denial (aka prevention): Restrict inmate access to unauthorized internal areas or the outside; provide physical separation for various inmate classifications; control inmate movement using sallyports, staff supervision; eliminate contraband passage with a secure perimeter
+- Detection: regular inmate counts, random cell counts, searches, guard notices inmate climbing wall, etc
+- Response: triggering lights, lighting selected area, closing gates, etc
+- Assessment: determining the nature, degree of a situation
+
+### Design focus
+- Creating an overall, 3d barrier called a security perimeter
+    - Prevents contraband from coming in
+    - Prevents unauthorized people from coming in or leaving
+- Internal security zones
+    - Control internal movement
+    - Maintain separation between key activities, inmate occupied areas, especially inmates who pose the highest risk
