Zoom is currently under tremendous scrutiny due to the massive increase in use of this software worldwide. As is typically the case for any software that comes under close scrutiny, some security issues have been discovered. These are issues that in the normal course of affairs would have been classified as medium or low severity, and Zoom has been responsive to the security and privacy feedback they've received.
In order to make sure that your meetings have the most up to date security and privacy features available, it is a good practice to keep your Zoom client updated. The Zoom client application currently does not auto-update, although logged-in users may receive a prompt to manually apply new updates. Rather than waiting for the prompt, we recommend periodically confirming that your version of the Zoom software is up to date.
Caltech's use of Zoom (i.e., any meeting hosted on caltech.zoom.us) falls under the Internet2 Net+ Zoom agreement, which was negotiated by a consortium of university attorneys and meets Caltech's privacy and security requirements.
There are many settings controls available to meeting hosts within the Zoom application that are relevant to privacy, and we recommend going over your settings before hosting a meeting or class.
