WipeOS supports the requirements of Clear and Purge according to IEEE 2883 - 2022
IEEE Standard for Sanitizing Storage
This standard has been developed by the Cybersecurity and Privacy Standards Committee
This standard details the methods for sanitization and physical storage, as well as for providing technology-specific requirements and guidance for the elimination of recorded data, are specific in this standard.
WipeOS support this standard in a variety of ways - here are some for reference.
On devices without Purge availability, we unlock the DCO and HPA, and overwrite on blocks. We have a method for working around SSD controller's wear leveling to overwrite every user addressible block.
For devices which support Purge commands, we also support these methods, including TCG Opal on devices which support it, cryptographic erase, security erase, and others.
We perform verification of sanitization on every method where applicable.
