The ISO 27000 series is a set of important security documents released by the International Organization for Standardization (ISO) to provide a guideline for best practices in IT security management, ISMS development and organizational security and risk management practices. The earlier documents (27001, 27002, etc.) serve as a baseline for this series, and many of the following documents build from that foundation.
Later documents in the series develop guidelines describing more specialized applications. One of these, ISO 27017, address security practices for the expanding area of cloud infrastructure that most of our business operations rely on.
