Is there any guidance on objectives or why you as a human risk and culture rep have been asked to present on network segmentation?
If segmentation has been identified as a weakness, I would consider asking an awareness rep, or any other rep, to simply give a non-specialized presentation ineffective and frankly unclear what the impact expectation would be.
As a security leader overseeing architecture, I would be looking for Azure/AWS training resources.
💡 Never agree to take on projects you know are pointless just because an executive thought it would make THEM look cute and supportive to give you a little pet project and watch you work. Instead, pass the buck back to the leader and convey why you aren’t the right resource to accomplish that objective.
