Hi everyone,
A customer is requiring a certificate of sanitization as per NIST SP 800-88 guidelines. I've done some research on my own but, from the articles I read, it is a bit of a grey area and I have hit a wall. I'm aware that in the background, google, AWS, and Azure are all following NIST SP 800-88 when it comes to decommissioning storage media but this doesn't really help me in providing a certificate to the customer. The guidelines recommend cryptographic erasure and provide some guidance on generally how to verify cryptographic erasure which seems to be the right direction but I am still not confident on how compliant data sanitization is performed in the cloud.
Does anyone have any experience with needing certificates of sanitization in the cloud that could help guide me in understanding the process? Any help is appreciated!
