What is secure disposal of media, and why is it important for a TA?

Secure disposal of media means making sure data on devices is irretrievable when the device is retired or repurposed. The goal is to prevent anyone from recovering erased information, protecting privacy and sensitive data from being exposed. For a trusted agent, this is essential because media often contain confidential information such as candidate data, exam materials, or system credentials. If disposal is sloppy, data could be recovered and misused, leading to privacy breaches, regulatory issues, and loss of trust. Techniques include secure data wiping, cryptographic erasure (destroying the keys so data becomes unreadable), degaussing for magnetic storage, and physical destruction for end-of-life hardware. In contrast, simply freeing up storage, allowing casual recovery, or focusing on hardware maintenance does not address the risk of data exposure after disposal.
