Keep inactive computers secure and up to date

Computers that sit idle for long periods can become vulnerable to security threats if they don’t receive regular updates. Even if a device is only used occasionally, keeping it up to date helps protect University systems and ensures it’s ready to go when you need it.

What You Need to Do

To help inactive computers stay secure, we recommend that they are switched on, logged into, and connected to the internet for several hours a couple of times a month.

You don’t need to actively use the computer during this time—just leave it on and connected so it can automatically receive important security updates for:

  • The operating system (Windows or macOS)
  • Installed applications such as Microsoft Office (Word, Excel, PowerPoint)
  • Web browsers (Chrome, Firefox, Edge)

Why This Matters

Inactive computers that are not updated regularly can become vulnerable to cyber threats. By connecting these devices periodically, you help protect both the computer itself and the wider Trinity network.

A More Secure Foundation

This recommendation follows the recent completion of Trinity’s rollout of Microsoft Intune and Defender to all managed Windows and macOS computers. These new cloud-based systems (introduced in July 2024 as part of the Cyber Security Programme) allow IT Services to manage encryption, anti-virus protection, and operating system updates for devices no matter where they are located.
