ISO 27001 data center control requirements

ISO 27001 does not prescribe specific controls for data centers, although controls from ISO 27001 Annex A can be applied to data centers as well. To identify which controls would be applicable to your data center you need to perform a risk assessment process. Some common adopted controls are:
- Physical Access Control
- Uninterruptible Power Supply (UPS)
- Audit Logs of all user activities and monitoring the same

 For requirements for a data center, you can take a look at the ANSI/TIA-942 standard. Although it is not ISO (it is an American National Standard) it provides several specifications considering availability and other security needs.
