Ensuring Operational Integrity and Security
Introduction
Proper equipment maintenance is essential to preserving the availability, integrity, and confidentiality of organisational information. By adhering to structured maintenance protocols, organisations can prevent loss, damage, theft, or compromise of information assets and minimise operational disruptions caused by equipment failures.
Purpose of Equipment Maintenance
The primary goal of equipment maintenance is to ensure the reliability and security of organisational assets, safeguarding against risks associated with inadequate maintenance. This includes protecting sensitive information, maintaining operational efficiency, and meeting compliance requirements.
Guidelines for Effective Equipment Maintenance
Scheduled Maintenance
Maintain equipment according to the supplier’s recommended service frequency and specifications to ensure optimal performance and longevity.
Maintenance Programme Implementation
Establish and monitor a comprehensive maintenance programme to address preventive and corrective needs proactively.
Authorised Personnel
Restrict repairs and maintenance activities to authorised personnel only. Ensure they are adequately trained and qualified.
Record-Keeping
Maintain detailed records of all suspected or actual faults, preventive measures, and corrective maintenance activities to track performance and identify recurring issues.
Controls During Maintenance
Apply appropriate controls when equipment is undergoing maintenance, whether on-site or off-premises. Ensure maintenance personnel sign confidentiality agreements and are supervised during the process.
Remote Maintenance Security
Authorise and control access for remote maintenance activities. Ensure secure communication channels and monitor remote sessions to prevent unauthorised actions.
Off-Premises Maintenance
When equipment containing sensitive information is taken off-premises for maintenance, apply relevant security measures (see Section 7.9). This includes tracking the equipment’s location and ensuring data protection.
Compliance with Insurance Requirements
Adhere to maintenance obligations imposed by insurance policies to maintain coverage and mitigate liability.
Post-Maintenance Inspection
Before returning equipment to operation, inspect it thoroughly to confirm it has not been tampered with and is functioning correctly.
Secure Disposal or Reuse
If equipment is deemed for disposal, apply secure disposal or reuse measures in accordance with organisational policies (see Section 7.14).
Types of Equipment Covered
Equipment requiring maintenance includes, but is not limited to:
Technical components of information processing facilities
Uninterruptible power supplies (UPS) and batteries
Power generators, alternators, and converters
Physical intrusion detection systems and alarms
Smoke detectors and fire extinguishers
Air conditioning systems
Lifts and other operational infrastructure
Supporting Measures
Confidentiality Agreements: Ensure all maintenance personnel are subject to confidentiality agreements to protect sensitive information.
Supervision: Supervise maintenance activities to monitor compliance with organisational policies and prevent unauthorised access.
Inspection Logs: Maintain inspection logs to verify that equipment meets operational and security standards.

Conclusion
Equipment maintenance is a critical aspect of organisational resilience and security. By implementing structured maintenance practices, organisations can ensure that their assets remain secure, functional, and compliant with operational standards.
A proactive approach to equipment maintenance reduces the risks of downtime, data breaches, and asset compromise, contributing to the overall stability and efficiency of the organisation.
