The document discusses the Trusted Site Infrastructure (TSI) certification program for data centers. It describes the TSI certification process and criteria, which evaluate the data center's physical security, technical security, and organizational security. The criteria cover factors like the data center building's location, structural protections against threats like fire, water, and electromagnetic interference, and maintaining defined temperature and humidity limits. TSI certification provides assurance that a data center has robust security measures in place to protect sensitive information and systems from various risks and failure scenarios.
