NIST SP 800-88 Rev. 2, Guidelines for Media Sanitization, frames sanitization as a program based on information sensitivity, media type, intended disposition, organizational risk, available techniques, verification, and documentation. Clear, purge, and destroy are categories whose suitability depends on the media and the organization’s requirements.
\nCISA’s guidance on protecting data stored on devices emphasizes understanding what data is present, controlling access, using encryption, maintaining backups, and securely disposing of devices and media. Those practices address confidentiality and recovery but do not replace malware prevention, safe transfer, or system-specific operating restrictions.
\nThe sources do not require one universal choice among prohibition, authorization, encryption, scanning, write restriction, managed media, or physical destruction. A recovery team, service technician, isolated operational system, and ordinary office user can have different legitimate needs and consequences.
\n\nBegin with the business workflow. Eliminate casual use, then provide a controlled path for the transfers and recovery functions that remain necessary.
\nInclude removable media in incident response. Define when a device is isolated, who may handle it, how a forensic image or hash is obtained when appropriate, how exposed systems are identified, and when credentials or data transfers require investigation. Do not reconnect suspected media merely to determine whether it still works.
\nFactual boundary: Sanitization effectiveness depends on media technology, device implementation, condition, encryption, and intended disposition. Antivirus scanning cannot guarantee a file is safe, and encryption does not prevent an authorized endpoint from reading malicious content. Legal, contractual, records, safety, and vendor requirements can change the appropriate control.
\nMeasure personal or unknown media detections, approved transfers, inspection failures, lost media, recovery-read tests, overdue returns, sanitization verification, and exceptions past expiry. The target is a usable controlled path with traceable custody—not a policy statement that ignores the work people must perform.
