How should dead files be destroyed in a secure manner?

Dead files should be destroyed securely by following established protocols, such as shredding physical documents using a cross-cut shredder to ensure they cannot be reconstructed. For electronic files, utilize data wiping software that complies with recognized standards, such as DoD 5220.22-M, to overwrite data multiple times, rendering it unrecoverable. Additionally, it's important to maintain a log of destruction activities to provide accountability and compliance with legal and regulatory requirements.
