Equipment Maintenance
Plain English Translation
ISO 27001 Annex A.7.13 requires the organization to correctly maintain its information processing equipment to ensure ongoing availability, integrity, and confidentiality. This involves following manufacturer guidelines for physical servicing, consistently deploying firmware updates, and maintaining an accurate log of all repairs or maintenance activities to prevent unexpected hardware failures.
Technical Implementation
Use the tabs below to select your organization size.
Required Actions (startup)
- Maintain a basic inventory of IT assets and ensure OS and firmware updates are applied automatically where possible.
- Rely on cloud providers to maintain physical server infrastructure and review their compliance reports.
Required Actions (scaleup)
- Establish an IT equipment maintenance schedule for all on-premise servers and network devices.
- Create a preventive maintenance checklist for IT equipment and retain logs of all completed service tasks.
Required Actions (enterprise)
- Implement automated patch management policy tools across all hardware endpoints.
- Enforce strict vendor supervision and a secure repair and servicing process (chain of custody) when third-party technicians perform maintenance.
It is a physical security control requiring that information processing equipment be maintained correctly to ensure the continued availability, integrity, and confidentiality of the organization's information.
Auditors look for ISO 27001 A.7.13 equipment maintenance evidence such as a documented Physical Security Policy, an equipment maintenance log template for audits filled with recent data, and compliance certificates from cloud providers. Tools like WatchDog Security's Compliance Center can help link these artifacts to the control and maintain an evidence trail over time.
An IT equipment maintenance schedule should align with manufacturer recommendations, statutory requirements, and the organization's own risk assessments to ensure optimal performance.
Yes, implementing a comprehensive patch management policy and following firmware update policy best practices are essential technical components of maintaining the integrity and security of the equipment.
You create it by identifying all critical hardware, establishing intervals based on manufacturer guidelines, utilizing a preventive maintenance checklist for IT equipment, and tracking it in an IT service management platform.
When looking at how to document hardware maintenance for ISO 27001, logs should include the date, the specific equipment identifier, the technician's name, a description of the service performed, and any parts replaced.
Organizations must enforce third-party maintenance access controls and supervision, ensuring external technicians are escorted, their logical access is restricted, and any maintenance is performed under a signed NDA. WatchDog Security's Vendor Risk Management can help document vendor onboarding, access requirements, and maintenance attestations as part of a repeatable workflow.
A secure repair and servicing process (chain of custody) must be maintained, and mandatory data sanitization before equipment repair or disposal must be completed to prevent unauthorized access.
Before performing maintenance, the organization should verify current backups exist, enforce least-privilege access for the maintenance tasks, and ensure full-disk encryption protects data at rest while the device is serviced.
Maintenance relies heavily on an accurate asset inventory and lifecycle management for compliance, utilizes defined maintenance windows and change management procedures to prevent unplanned disruptions, and acts as a core proactive measure for incident prevention.
A common challenge is keeping maintenance schedules, logs, and related policies consistent across teams and sites. Tools like WatchDog Security's Compliance Center can centralize the control requirements, map them to evidence requests, and track maintenance records and review cadence in one place for audit readiness.
Third-party servicing often creates gaps in documentation (who accessed what, when a device left the site, and whether data was sanitized). WatchDog Security's Vendor Risk Management can help maintain vendor records and assessments, while WatchDog Security's Secure File Sharing can be used to exchange repair attestations and chain-of-custody documents with strong access controls and audit logs.
