Since this article came out, Zoom has updated a previously published blog post detailing many of the tools it has that educators can use to prevent these problems (https://blog.zoom.us/wordpress/2020/03/27/best-practices-for-securing-your-virtual-classroom/). In addition, educators have created wonderful checklists for those who want to use this option (I’m attaching one example to this email).
As for the FERPA issue, I know that Zoom made several updates over the past week and published information on its blog on March 29th (after the Edsurge article) regarding its compliance with FERPA (https://blog.zoom.us/wordpress/2020/03/29/zoom-privacy-policy/).
I actually find that Edsurge article to be very misleading. I have not seen any report that indicates that people are actually “hacking” into Zoom meetings. Rather, people are not using the security features that Zoom has provided and/or are posting the links. Edsurge also does not use the word “hack” anywhere except in the title.
