I am Stuart Barker, the ISO 27001 Lead Auditor and author of the Ultimate ISO 27001 Toolkit.
Using over 30 years of industry experience across hundreds of audits, I’m giving you the exact templates, walkthroughs, and practical examples you need to achieve ISO 27001 certification.

Implementing ISO 27001 Annex A 7.14 Secure Disposal or Re-use of Equipment is a mandatory security protocol for managing end-of-life hardware. The Primary Implementation Requirement involves forensic-grade media sanitisation and verifiable decommissioning logs, delivering the Business Benefit of eliminating data breach risks from retired hardware assets effectively.
1. Establish a Physical Hardware Decommissioning Log
Control Requirement: Equipment containing storage media must be verified to ensure sensitive data is removed before disposal.
Required Implementation Step: Open a physical or local spreadsheet log and record every device serial number destined for retirement. Cross-reference this with your master asset register to ensure “ghost” devices aren’t being handed to recyclers without formal tracking.
Minimum Requirement: A serial-numbered list of all equipment awaiting disposal, physically matched to the items in the secure “holding” area.
2. Secure Physical Holding for End-of-Life Assets
Control Requirement: Items awaiting disposal must be protected from unauthorised access.
Required Implementation Step: Clear a space in a locked server room or a caged area for decommissioned hardware. Do not leave “old” laptops under desks or in open cupboards; if the storage media hasn’t been wiped yet, it is a live data breach risk sitting in plain sight.
Minimum Requirement: A locked, restricted-access room or cage used exclusively for equipment pending sanitisation.
3. Execute Forensic-Grade Media Sanitisation
Control Requirement: Data must be made unrecoverable using recognised standards.
Required Implementation Step: Use a hardware-based “wiper” or certified software (e.g. Blancco) to perform a NIST 800-88 Purge or Clear. Standard OS formatting is insufficient; you must run a multi-pass overwrite and generate a technical log proving every sector of the HDD or SSD was addressed.
Minimum Requirement: A technical sanitisation report for every drive, matched explicitly to the device serial number.
