Google Infrastructure Security Design Overview

This document provides an overview of how security is designed into Google’s technical infrastructure. It is intended for security executives, security architects, and auditors.

We design and build our own data centers, which incorporate multiple layers of physical security. Access to these data centers is tightly controlled. We use multiple physical security layers to protect our data center floors. We use biometric identification, metal detection, cameras, vehicle barriers, and laser-based intrusion detection systems. For more information, see Data center security.
