Episode 28: Data Remanence and Secure Disposal Techniques

from Certified: The CISSP Audio Course Hosted by Dr. Jason Edwards

Even when you delete a file, remnants can linger—posing serious security risks. This episode delves into the concept of data remanence and the techniques used to ensure secure data disposal. You'll learn about data wiping, degaussing, shredding, cryptographic erasure, and the standards that guide their use, such as NIST SP 800-88. We also cover the importance of disposal audits, chain of custody for media, and the role of policy in enforcing proper end-of-life procedures. Secure disposal is a small step with massive implications for data confidentiality.
