As an offshoot of the recent Network Renewal Programme, ICTS is introducing Network Access Control (NAC) mechanisms on the UCT wired network across campus. NAC will enhance network security on campus and help us to align with our cyber insurer’s requirements, and comply with  a range of local and international standards and legislation. This new feature will ensure that every device connecting to our network via cable is authenticated and that the user or device owner can be identified by their UCT network account. It will also pave the way for network segmentation – an upcoming security measure which will further enhance control around access to specific UCT servers and services. 

When will this happen?

The change will be implemented to all buildings on campus over October 2023.

What do I need to do?

If your device connects wirelessly, you don’t need to take action.

However, if you connect any device on campus using a network cable, you will need to configure that device by 24th October 2023.

To do so, please follow the instructions below relevant to your operating system for each wired device you use on campus:
