How can I ensure my Zoom meeting will not be disturbed by attackers?

There are many way of protecting a Zoom meetings, you can see a list here https://zoom.us/security and also https://zoom.us/docs/doc/Securing%20Your%20Zoom%20Meetings.pdf.

However the basic option for securing a meeting is to protect it with a passcode. If you do so, make sure you do not advertise the passcode or the Zoom URL including the passcode hash on a public page.

If your event is a public event, then you may want to choose the webinar format instead (see https://support.zoom.us/hc/en-us/articles/115005474943-Meeting-and-webinar-comparison) as it gives a better control over the participants.
