Episode 110: Secure Disposal and Media Sanitization

Data doesn’t disappear just because you delete it. In this episode, we focus on how to securely dispose of media and sanitize storage devices to prevent data recovery. We cover techniques such as overwriting, degaussing, cryptographic erasure, and physical destruction, as well as when and how to apply each. You’ll also learn about documentation requirements, chain of custody for retired media, and applicable standards like NIST SP 800-88. CISSPs must ensure that end-of-life processes are consistent, auditable, and aligned with regulatory and organizational data protection obligations.
