YALE-MSS-7.6: Delete data when it is no longer required
Details
Removing unneeded data reduces risk.
When the use and retention period of data is complete, that data must be:
- destroyed,
- rendered unrecoverable, or
- returned to the owner
If the data are not available anywhere else, the University may require you to keep them. Review the Yale Records Retention Schedule maintained by the Office of General Counsel. This outlines how long certain records must be preserved.
For normal use of a system with full-disk encryption, it is acceptable to delete files through the operating system's features (e.g., dragging a file to a trashcan and emptying the trash, or issuing an appropriate delete command from a command prompt).
For systems without full-disk encryption, delete data using operating system utilities and ensure procedures for repurposing and recycling are followed.
