This document discusses implementing security measures in multiple layers or "rings" to protect assets. It recommends conducting a security threat assessment and identifying probable threat elements before implementing security systems. A local security expert can then guide setting up deterrents like barriers and lighting to prevent threats. Detection systems like CCTVs and intrusion detection help identify threats attempting to enter. Assessment, delay, response, and denial systems activate as threats progress further to ultimately protect the core assets. The document stresses centering all security efforts and systems around saving protected assets.
