Is your operating system up to date?
If you are working from home on own PC or laptop, we expect you to be using Windows 10/MacOS High Sierra (or later) and to have the latest security updates installed. Read how to here. If your computer is too old to do so, please consider buying a new one or discuss a temporary solution with your manager.
It is extremely important for not only your own security but also that of the University network that you work with up-to-date software. The ISSC is monitoring whether people are using computers with outdated operating systems to log into systems such as Office 365 or Microsoft Teams. They will contact anyone who does and remind them to update their operating system.
