Key concepts
The guide summarizes the clear, purge and destroy methods, including cryptographic erase, and asks organizations to choose a method based on data sensitivity, verify results and keep records. Detailed per-device instructions moved to referenced standards such as IEEE 2883. A sample certificate of sanitization is included.
How it is organized
- Background
- Summary of sanitization methods: clear, purge, destroy, cryptographic erase
- Media sanitization program: roles, sensitivity-based decisions, verification, documentation
- Appendices: device characteristics, sample certificate of sanitization
What a school district should take from it
- Contracts that cite 'SP 800-88 Rev. 1' are out of date; update them to Rev. 2.
- Require a certificate of sanitization from recyclers and resellers, listing each device.
- Copiers, phones and network gear store data too.
How to use it in your district
- Write a one-page sanitization procedure covering laptops, Chromebooks, servers, copiers and phones.
- Update recycler and lease-return contracts to require SP 800-88 Rev. 2 methods and per-device certificates.
- Record disposed devices in your inventory with the certificate as evidence.
- Spot-check a sample of wiped devices before they leave district custody.
Common misconceptions
- Deleting files or a factory reset is enough.
- Depending on the device and data, you may need purge or destroy methods, and you should verify the result.
