The human fire wall is a term used in this video to describe the protection that humans can provide protection in cyber security. One of the biggest thing that the guest mentioned was that cyber security is not a technology issue but a human issue. Including the fact the internet is a tool that can be used to breach and gather data. Its a global tool and relativism  plays a role in the way cyber criminals take their approach such as attacking the US more while contact wars take place/ The biggest issue though that he brings up in the video is AI or specifically Chat-GPT . The issue is that it gives non-technical and other paradigms within its code that process that humans cannot properly detect.
