Minimum Security Standards

These standards are intended to reflect the minimum-security configurations necessary for devices that create, access store or transmit Yale data. Devices should be configured in accordance with the highest data classification used on the device.

Every data user is responsible for ensuring the appropriate level of security for the data they use. More information on this requirement can be found in Procedure 1604 PR.01. Additionally, any Data User creating, accessing, storing or transmitting personally identifiable patient information or human subject data is required to comply with the Yale University HIPAA Policy 5100.

Please note that these standards will be revised and updated accordingly to ensure and compliance with current cybersecurity best practices.

Critical IT Spaces 

All Critical IT Spaces are required to meet the Minimum Physical Security Standards for Critical IT Spaces

Critical IT Spaces are defined as any area that contains Critical IT Infrastruture. Critical IT Infrastructure can contain low, moderate, or high risk data and is defined as any IT System that meets 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 and needs special protections beyond Yale’s Minimum Security Standarsd.
