Google Reveals Its Servers All Contain Custom Security Silicon
Google has published an Infrastructure Security Design Overview that explains how it secures the cloud it uses for its own operations and for public cloud services. From a report on The Register: The document outlines six layers of security and reveals some interesting factoids about the Alphabet subsidiary's operations, none more so than the disclosure that: "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." That silicon works alongside cryptographic signatures employed "over low-level components like the BIOS, bootloader, kernel, and base operating system image." "These signatures can be validated during each boot or update," the document says, adding that "the components are all Google-controlled, built, and hardened. With each new generation of hardware we strive to continually improve security: for example, depending on the generation of server design, we root the trust of the boot chain in either a lockable firmware chip, a microcontroller running Google-written security code, or the above mentioned Google-designed security chip."Read more of this story at Slashdot.
