In the current era of technology, the IT infrastructure plays a critical role in the functioning of any organization. 

It is important to ensure that the supporting utilities and equipment are functioning properly to minimize the risk of downtime and potential losses. 

In this article, we will discuss one of the important aspects of information security – equipment maintenance. 

We will provide a checklist to help you assess whether the equipment in your organization is being properly maintained and serviced by qualified personnel.

Sample Checklist:

  • Qualified personnel: Verify that only qualified personnel carry out maintenance of equipment. This includes infrastructure and network devices, laptops, desktops, safety and utility equipment such as smoke detectors, fire suppression devices, HVAC, access control, and CCTV.
  • Manufacturer’s specifications: Check that the equipment is maintained and serviced according to the manufacturer’s specifications. This ensures that the equipment is functioning properly and reduces the risk of potential failure.
  • Maintenance schedules and logs/reports: Are there up-to-date maintenance schedules and logs/reports? Regular maintenance ensures that the equipment is in good condition and prevents unexpected failures.
  • Insurance requirements: If the equipment is insured, verify that the maintenance and other requirements of the insurance contract are satisfied. Failure to comply with the insurance requirements may result in a loss of coverage in case of an incident.
