We recommend that users familiarise themselves with all the available Zoom security features that they can apply to have safe online meetings.

It is also recommended that users are using the latest Zoom software. Find out more about how to update your Zoom software.

When a user (host) schedules a Zoom meeting, it is recommended to

1. select "Generate Automatically" meeting ID. Using different meeting IDs for different meetings is safer than using same meeting IDs as the reuse of meeting IDs can accidentally be joined by uninvited participants.
2. select "Require meeting password". This will protect the meeting from being joined by uninvited participants who may interrupt the meeting with "Zoombombing". 
3. and under "Meeting Options" 
   • don't select "Enable join before host" if it is not necessary and if this is a recurring/perpetual meeting.
   • select "Mute participants upon entry". This will ensure participants do not share audio when they are not ready.
   • select "Enable waiting room". This can help the host of the meeting to not let unwanted participants into the meeting.
   • if it is an internal meeting or a virtual classroom with expected participants, select "Only authenticated users can join".

During the Zoom meeting, the host of the meeting can make use of Zoom host controls to have secure and safe meetings. These includes

1. Available from version 4.6.10, there is the Security icon in meeting controls that allows quick and easy to find access to security features.                                                              
2. the host ability to manage all participants. Click on "Manage Participants" to see the participant list.

   2. Click on "More" to see the options to ...                      
      • Mute Participants on Entry. This will prevent unwanted noise from new participants who aren't ready.
      • Allow Participants to Unmute Themselves. This is useful to not allow especially in a classroom scenario if the students are noisy.
      • Allow Participants to Rename Themselves. This is useful to not allow especially if all the participants are authenticated to join the meeting.
      • Play Enter/Exit Chime so there is awareness of presence of participants. This may not be suitable to turn on for meetings with large participants.
      • Put Participants in Waiting Room on Entry so the host can admit only allowed participants into the meeting.

   2. have in-meeting chat.
      • Click on "Chat" and then the "[...]" to select who participants can chat with 

After the meeting, the host may collect recorded content from the meeting. The host will ensure that the collected content from the Zoom meeting is stored in a safe place, this includes ...
