prevent "zoom bombing"

"Zoom BomBing"

"Zoom Bombing" occurs when uninvited guests join Zoom meetings, take over the screen/audio, and share inappropriate or offensive comments and images. Unfortunately, "Zoom Bombing" is a very real concern for schools using Zoom during the COVID-19 Emergency.

Zoom is a powerful tool, though, so we do not want the possibility of "Zoom Bombing" to deter our use of Zoom at NSSEO to support Distance Learning. The recommendations below will help minimize the risk of "Zoom Bombing" occuring during one of your Zoom Meetings and will give you to tools to respond quickly and effectively in the case that it does occur.

Tips for SECURELY setting up a Zoom Meeting:

Tip #1: Remember, this too shall pass

Many educators have used tools like Zoom for years without experiencing this issue. Once this period of disruption has passed, you can loosen up the reigns on your meeting settings.

Tip #2: Trust your students

This is a very stressful time for students too. While you should take precautions to ensure your Zoom meetings are attended only by your students, be careful that your students don’t interpret your actions as a sign of distrust in them. Be open with them about what has been happening and let them know that you’ll be taking extra precautions to create a safe, welcoming environment for them.

Tip #3: Make sure you do NOT share your Zoom link publically

Do not share your Zoom meeting information on social media or in any other public location (i.e., website, Google Doc with link sharing available).

Additional options for added security when setting up a Zoom meeting:

These options will help protect your Zoom meeting from uninvited participants when you schedule the meeting. They may add time to getting a class or meeting started, however, as participants either use a password or wait to be admitted. That should be factored into the decision to use these features.

Use a Random Meeting ID

Avoid using your Personal Meeting ID (PMI) to host public events. Your PMI is essentially one continuous meeting and people can pop in and out all the time. Learn about meeting IDs and how to generate a random meeting ID (at the 0:27 mark) in this video tutorial.

Password Lock your Zoom Meeting

You have the option to password lock a Zoom meeting to hinder unwanted guests from accessing your Zoom meeting. It is recommended that you only share this password with those who will be attending the meeting, and to have a strong, secure password. Note that the password feature is only available when scheduling a meeting, not when starting a new meeting immediately. To set a password on your Zoom meeting, please follow the instructions below.

NOTE: Participants who get dropped from the meeting due to network connectivity issues or mistakenly closing the window will be unable to rejoin a locked meeting.

    1. Open your zoom application and log in to Zoom.

    2. Click on the [Schedule] icon.

    3. Set your preferred meeting options.

    4. Under Password, check [Require Meeting Password].

    5. You may notice that a password is set for you. We recommend changing the default password to something much stronger.

    6. Once you have entered the preferred password, it will be set once you officially schedule the meeting. Users will be prompted to enter a password once the meeting participants join the meeting they were invited to. The password can be found in the meeting invitation.

Use a Waiting Room for Participants

When you require a waiting room for participants, this will force users to wait for approval before entering a meeting. This gives you, the host, the option to deny any unwanted participants and monitor those who are waiting to enter the meeting. To set up a waiting room, please follow the instructions below.

    1. Open your Zoom application and log into Zoom.

    2. Click on the [Schedule] icon.

    3. Set your preferred meeting options.

    4. Under Advanced Options, check [Enable Waiting Room]. This will take effect once you officially start the scheduled meeting.

    5. You will not see the participants who are waiting until they accept the meeting and join. They will first be “waiting” before being able to participate in the meeting.

    6. To admit the participant into the meeting, click [Manage Participants] and hover over the name of the person waiting and click [Admit].

Tip #4: Do not allow students to create their own Zoom accounts

  • Students should NOT create their own Zoom accounts (using NSSEO or personal emails), this is a violation of children’s privacy laws and protections.

  • Students CAN join a Zoom meeting created by their teacher/therapist, this does not require the students to create a Zoom account

Tip #5: Configure the settings for your meeting to match your needs

The host of a Zoom meeting has many options to help manage participation by attendees and protect against unwanted participation. Choose the options that best align to your needs and the planned structure and activities for your Zoom Meeting.

Tips for Managing Participants in a Meeting (external link): The video at the top of the page gives a great overview of the host features and options you can use to manage the participants in your meeting.

Set Participants to Mute

Zoom allows you to mute single participants or mute all participants. You are also capable of muting individuals instantly upon joining the meeting.

Muting Individuals

    1. Once the Zoom meeting has started, select [Manage Participants] in the Zoom Task Bar at the bottom of the meeting.

    2. In the sidebar that appears, hover over the participant you would like to mute and select [Mute].

Muting All Participants

    1. Once the Zoom meeting has started, select [Manage Participants] in the Zoom Task Bar at the bottom of the meeting.

    2. In the sidebar that appears, click [Mute All] at the bottom to mute all participants.

    2. In the sidebar that appears, click [More] in the bottom right.

    3. In the drop-down that appears, select [Mute Participants on Entry].

      • NOTE: If you do not want participants to be able to unmute themselves, please be sure to uncheck [Allow Participants to Unmute Themselves].

Limit Screen Sharing as Needed

Giving students the opportunity to share their work is a powerful feature of Zoom, but you may want to limit the times during the meeting that this is allowed.

After you start a Zoom meeting, you can change the Screen Share settings to limit who can and cannot share their screen.

    1. In the Zoom toolbar, select the caret next to Share Screen

    2. In the Advanced Sharing Options window, make these adjustments:

        • How many participants can share at the same time?

          • Select One participant can share at a time

        • Who can share?

          • Select Only Host

    3. When you get to a point in your meeting that you want students to share, simply return to the same Advanced Sharing Options and adjust the settings.

Disable Attendee Annotation

If you have Annotation enabled in your settings, that means attendees will be able to annotate on your shared screen at any time.

While this feature can be great for collaborative activities, you can easily deactivate the feature but only once you have begun to share your screen. Follow these steps:

    1. Share your screen

    2. Click More in the screen share controls

    3. Select Disable participants annotation

If you wish to encourage students to annotate your shared screen, simply re-enable the feature by following the same steps.

Lock the Meeting

Zoom meetings can be locked after they have started to ensure no other participants can join. When you lock the meeting, no new participants can join, even if they have the meeting ID and password. In order to lock a meeting, follow these steps:

    1. Once the Zoom meeting has started, select [Manage Participants] in the Zoom Task Bar at the bottom of the meeting.

    2. In the sidebar that appears, click [More] in the bottom right.

    3. In the drop-down menu that appears, select [Lock Meeting].

    4. A warning prompt will display to warn you that no new attendees can join, select [Yes].

Block Name Changes

Zoom allows you to block the ability to change names and profile pictures of meeting participants.

    1. Once the Zoom meeting has started, select [Manage Participants] in the Zoom Task Bar at the bottom of the meeting.

    2. In the sidebar that appears, click [More] in the lower-right corner.

    3. Click [Allow Participants to Rename Themselves] to disable the feature.

Tip #6: Protect Student Privacy by NOT recording Zoom meetings

If you are using Zoom with students, do not record any video, audio, or chat that features students images, voices, or student names.

However, you may wish to record yourself providing a mini-lesson for students to be shared via SeeSaw or Remind, this can be done using a Zoom Meeting in which you are the only participant. This is a great tool for Distance Learning!

Here’s a Blog Post and Video that describes how you can do this.

Tip #7: Be prepared to respond "Just in Case" your meeting is disrupted

If a disruptive, uninvited attendee appears in your meeting, you can manage the situation by following these steps:

Stop Unwanted Screen Sharing

    • Share your own screen. You are the host and you may take screen sharing over from attendees.

Stop Unwelcome Webcam Video or Sounds

    1. Select the Manage Participants button in the toolbar.

    2. Locate the person’s username (which will also be at the top of their video).

    3. To the right of their name, mute their webcam and/or microphone.

Remove the Person from the Meeting

There may be times where you will need to remove a participant in your Zoom meeting. To do so, please follow the instructions below:

    1. In your meeting, select Manage Participants.

    2. A list of the attendees should appear on the right.

    3. Hover your mouse over their name until the [More] button appears. Click [More].

    4. You should see an option to remove the user. Once you confirm their removal, they will be removed from the meeting.

    5. For an added layer of comfort, you may consider Locking the meeting (see above). Remember, doing this would also prevent your own students from entering.
