Google Infrastructure Security Design Overview


This document gives an overview of how security is designed into Google’s technical infrastructure. This global scale infrastructure is designed to provide security through the entire information processing lifecycle at Google. This infrastructure provides secure deployment of services, secure storage of data with end user privacy safeguards, secure communications between services, secure and private communication with customers over the internet, and safe operation by administrators.

Quite a few interesting bits in this document, including this:

A Google data center consists of thousands of server machines connected to a local network. Both the server boards and the networking equipment are custom-designed by Google. We vet component vendors we work with and choose components with care, while working with vendors to audit and validate the security properties provided by the components. We also design custom chips, including a hardware security chip that is currently being deployed on both servers and peripherals. These chips allow us to securely identify and authenticate legitimate Google devices at the hardware level.
