NIST SP 800-88 NISTSP88-5: Media Inventory, Tracking, Chain of Custody, and Sanitization Records

Maintain media inventory and tracking per NIST SP 800-88 Rev 1 Chapter 3 (Information Sanitization Process) + Chapter 4 (Decision Flow). Inventory must (a) track every piece of storage media from acquisition through sanitization or destruction, (b) record media type + serial number + system assignment + security categorization + data classification + location + ownership, (c) tag media at acquisition to enable lifecycle tracking, (d) interface with property management + IT asset management + records management + procurement systems. Chain of Custody per Section 3.4 must (a) document transfer of media between custodians at every step (system owner to sanitization personnel to disposal vendor to disposition), (b) record handler identity + date + time + purpose + receiving party + verification of integrity, (c) survive across organisational boundaries (when media leaves the organisation) with signed handover documentation, (d) align with legal hold + e-discovery + litigation requirements. Sanitization records per Section 4.7 + Appendix G must capture (a) Certificate of Sanitization (Section 4.8) for every sanitization event covering media identification + sanitization method + date + personnel + verification + witness where applicable, (b) record retention aligned with regulatory + investigative + organisational policy (typically minimum 3 years + longer for high-sensitivity media).
