A government agency needs to dispose of hard drives containing classified information. Which data destruction method provides the highest level of assurance that the data cannot be recovered?
Degaussing the hard drives
Physical destruction of the storage media
Multiple-pass overwriting
Cryptographic erasure
Physical destruction, such as shredding or pulverizing hard drives, provides the highest level of assurance that data cannot be recovered. This method physically damages the storage media beyond repair, making data recovery impossible even with advanced forensic tools. While degaussing can be effective for magnetic media and overwriting can work for functioning drives, neither provides the same level of assurance as complete physical destruction. Cryptographic erasure relies on the strength of encryption and key management, which could potentially be compromised. For highly classified or sensitive information, physical destruction is the recommended approach to ensure data is permanently and irreversibly destroyed.
