Secure Disposal or Re-use of Equipment
Plain English Translation
ISO 27001 Annex A.7.14 requires organizations to verify that any hardware containing storage media, such as laptops, servers, or external drives, is thoroughly wiped of sensitive data and licensed software before it is disposed of, sold, or reassigned to another user. This ensures that confidential information cannot be recovered by unauthorized parties and that the organization remains compliant with software licensing agreements when equipment leaves its direct control.
Technical Implementation
Use the tabs below to select your organization size.
Required Actions (startup)
- Ensure all laptops have full-disk encryption enabled by default so that a simple factory reset securely crypto-erases the stored data.
- Manually verify that local user data and licensed software are removed before giving a used device to a new employee.
Required Actions (scaleup)
- Implement an end-of-life IT asset management process that standardizes device wiping using industry-standard tools (e.g., NIST 800-88 compliant secure erase).
- Collect and safely store a certificate of data destruction for every hard drive or device sent to an external recycling vendor.
Required Actions (enterprise)
- Automate the tracking and verification of secure data destruction across global offices using centralized IT Service Management (ITSM) platforms.
- Perform physical destruction (e.g., shredding or degaussing) on-site for highly classified media before handing the remnants over to third-party disposal services.
It requires organizations to verify that items of equipment containing storage media have any sensitive data and licensed software removed or securely overwritten prior to disposal or re-use.
Verification involves establishing documented procedures aligned with industry standards like NIST 800-88, utilizing specialized wiping software that confirms successful erasure, and maintaining a verifiable audit trail or log.
Acceptable methods depend on the media type and data sensitivity, ranging from multiple-pass secure overwriting for older magnetic drives, to secure erase commands and crypto-erase for modern encrypted solid-state drives.
Traditional overwriting is generally insufficient for SSDs due to wear-leveling algorithms. Organizations must use manufacturer-supported secure erase commands, cryptographic erasure, or physical shredding to properly sanitize SSDs.
Degaussing or physical shredding should be used when storage media is severely damaged and cannot be wiped via software, when dealing with highly classified information, or when the cost of software wiping exceeds the value of the hardware.
Auditors typically expect to see an IT equipment disposal policy, tracking logs indicating chain of custody, and a formal certificate of data destruction for each disposed asset containing storage media. Tools like WatchDog Security's Compliance Center can centralize these records and link them to the A.7.14 control for easier retrieval during audits.
Yes, if an organization uses a third-party vendor to dispose of equipment, obtaining a formal certificate of destruction is a critical piece of audit evidence to demonstrate the control was effectively met.
Organizations must follow standard procedures to uninstall or securely overwrite licensed software to prevent software piracy, ensure compliance with vendor licensing agreements, and avoid unnecessary ongoing license consumption.
Mobile devices and tablets should be factory reset using built-in secure wipe features, often managed centrally via Mobile Device Management platforms, while inexpensive removable media like USB drives are typically physically destroyed.
The policy should detail the end-of-life IT asset management process, specify approved sanitization methods for different storage media types, outline chain of custody requirements, and mandate the removal of licensed software before reassignment.
A common failure point is losing the audit trail between decommissioning, sanitization, and vendor disposal. Tools like WatchDog Security's Asset Inventory can maintain an asset-level record of lifecycle status, custody, and disposal evidence, while WatchDog Security's Compliance Center can organize certificates of destruction and related logs as control evidence for audits.
The risk usually comes from inconsistent offboarding and rebuild steps across teams, which can leave licensed apps installed or credentials cached. WatchDog Security's Policy Management can publish and track acceptance of standardized disposal and re-use procedures, and WatchDog Security's Asset Inventory can help confirm which devices are being reassigned so the right removal and wipe steps are consistently applied.
