The school has a few security measures in place to ensure students are not going to inappropriate sites based on content. In this day there are more students being sent to YouTube to watch educational videos that are assigned by the teacher, so YouTube is not blocked. However, the issue that is students have figured out that in PowerPoint if they click "Insert" a "Video" they can search for whatever videos on YouTube and watch them within their slide, then delete them (or save them in their own PPT and share with their friends. The school has a web content filter that parents can monitor their child's internet history, but these videos do not show up. Additionally, it does not show up in the browser history. Is there something that can be done to at least detect these and have them logged in the browser history at least? I have done a lot of searching and the most that I found was setting a GPO that disables inserting videos in PPT, but that does not work because the students make presentations in PPT and have to post videos of themselves or other things in them. We are just trying to figure out how to detect it and go from there.
When a video is embedded in a document, the browser is the document application, here PowerPoint. So it is perfectly normal that it does not appear in the browser history. But if you use an outgoing proxy, it should appear in the proxy logs, with a reference to the machine that downloaded it. From there on, it should be possible to detect unexpected videos and who whatched at them.
It is often enough to explain students that they are not anonymous when whatching videos and that their parents will be informed to have them stop it... Additionally, explaining them that anonymity in Internet is not as trivial as they think, and that not only the schoool but others like their future employer could search their past activity would be very profitable.
