Minimum Physical Security Standards for Critical IT Spaces
What is a Critical IT Space?
Critical IT Spaces are areas that contain Critical IT Infrastructure. Critical IT Spaces include:
- Data Centers (e.g. Amazon Web Services, Microsoft Azure, Google Cloud Platform)
- Network/Telecom main distribution rooms
- Telecom remote closets
What is Critical IT Infrastructure?
Critical IT Infrastructure is an IT System that meets any of the following criteria:
- An IT system that unrelated IT systems have a dependency on, and/or;
- An IT system that is complex or specialized in nature. This complexity requires special protections beyond Yale’s Minimum Security Standards.
All Critical IT Infrastructure is designated by Yale’s Chief Information Security Officer. Email us with any questions, including:
- The designation of an IT System as Critical IT Infrastructure.
- The designation of an area as a Critical IT Space.
Minimum Physical Security Standards for Critical IT Spaces
These physical security standards categorize Critical IT Spaces based on their criticality.
- Level 1 Critical IT Spaces include Data Centers and Network/Telecom main distribution rooms.
