Privacy and information security for the McMaster community are of paramount importance. With the recent addition and availability of the Zoom video conferencing service, some privacy concerns have been raised by the campus community. This article addresses some of these concerns and provides Zoom users with some best practices to protect their privacy and the privacy of others. Please find below some of the common issues raised to our support teams, along with advice for members of our community using Zoom.
Zoom bombing is when an uninvited participant joins a Zoom web conference anonymously and disrupts the meeting with unwanted language and content sharing. This practice has gained a lot of attention in the media because of a few unfortunate incidents in online lectures hosted by other higher education institutions.
To prevent Zoom bombing, customers of the service are advised familiarize themselves with the security features on the service and to manage attendance and the actions of participants within each Zoom web conference:
For more guidance on the prevention of Zoom bombing please review this article.
Many websites track your access to their site. For example, third-party services such as Google Analytics, Facebook and DoubleClick, track your surfing habits to drive targeted advertising. For a more detailed overview about how trackers work and the information that they collect please review the following article on how these third party platforms track what you do on the web.
Zoom does use some of these services, however these services are NOT used at the https://mcmaster.zoom.us login page. Google Analytics is used after you have logged in.
If you would like to prevent web advertisers from tracking your surfing habits, we recommend using a privacy browser extension such as Privacy Badger. Privacy Badger is available for most commonly used browsers and will prevent third-party trackers from accessing your information. Using Privacy Badger does not affect the ability to join a Zoom call, nor does it impact audio and video quality while in a conference or meeting.
With this feature, the meeting host can determine if participants are being attentive to the conference or meeting, or if they are doing other things while listening in. This feature is disabled and not available for use by McMaster users.
Hosts have the ability to record Zoom sessions and are advised to be transparent with participants when doing so. Hosts also have the ability to grant participants to record sessions and to store those recordings on the participant’s local computer. Hosts are likewise advised to be transparent with all participants when granting such permissions to individual participants.
It is possible for participants to use third party applications to record sessions without the host’s permission or knowledge. This risk exists with all web conferencing services and is not unique to Zoom. Hosts should be aware of this risk and manage the content shared within the service accordingly. We will continue to identify opportunities to configure the Zoom service to improve the privacy of hosts and participants as it relates to recording.
The IT Security team continues to explore ways in which security can be improved within the Zoom platform and will update these best practices with up-to-date information.
