Ensure Security of Unused IT Equipment and Media
IT equipment and media are protected against unauthorized access when not actively being used.
Plain language
This control is about making sure that computers, hard drives, and other tech devices are safely locked away when you're not using them. It’s important because if someone can get to them when you're not watching, they could steal important information or mess up your business operations.

IT equipment and mediaOfficial control statement
IT equipment and media are secured when not in use.
Why it matters
If unused IT equipment or removable media aren’t secured when not in use, they can be stolen or accessed, leading to data exposure and disruption.
Operational notes
Lock unused devices and removable media in secure storage (e.g., cabinets/rooms), restrict key/access lists, and audit holdings regularly to confirm they remain secured.
Implementation tips
- Managers should ensure staff know where to store equipment: Hold a short training session to show employees the designated secure storage areas like locked cabinets or secure rooms. Use clear signage and reminders around the office to reinforce the practice.
- IT teams should label and log equipment: Create a simple log of all IT equipment that includes who it's assigned to and where it should be stored when not in use. Use asset tags on devices to make tracking easier and do regular checks to ensure devices are where they should be.
- Office managers should install locks on storage areas: Recognise areas where IT equipment is stored and fit them with secure locks. Consider using combination or key locks and maintain a list of authorised persons who have access.
- Employees should be reminded to sign out equipment: Implement a sign-out sheet or digital system for tracking who takes devices out of secure storage. Include checking the condition of the devices upon return to ensure nothing is damaged or missing.
- Procurement teams should ensure purchase of lockable storage: When buying new IT equipment or media, also consider lockable cabinets or safes to store them securely when not in use. Prioritise highly portable or sensitive equipment like laptops and external drives.
