Security especially due to the rapid increase in the use of platforms such as Zoom.
Despite its convenience and flexibility, there are many vulnerabilities that hackers can exploit, putting participants' privacy and security at risk. In this article, we will examine the most common vulnerabilities identified in Zoom and suggest measures to strengthen security in video conferences.

What are the most common vulnerabilities in Zoom?
One of the most common vulnerabilities in Zoom is the lack of protection for video conference links. These links can be easily shared or discovered by hackers, allowing them to enter video conferences without an invitation.
Using weak or non-existent passwords for video conferences is a significant vulnerability. Without strong passwords, video conferences are vulnerable to unwanted intrusions.
Lack of two-factor authentication (2FA) for participants can lead to access by unauthorized individuals. Without adequate authentication, it is difficult to ensure that only invited people are participating in the conference call.
Not updating Zoom to the latest version can leave the app vulnerable to security holes. Updates often include fixes for vulnerabilities and are critical to maintaining security.
What are the basic safety measures that need to be taken?
One of the key security measures we should take is to use strong and unique passwords for each video conference. These passwords should be difficult to guess and include a combination of letters, numbers, and special characters.
It is important to enable the “Waiting Room”, which allows us to control who tries to enter the video conference and only allow entry to people we know and trust.

Using the “Lock Meeting” after the meeting starts can prevent hackers from breaking in. Once all invitees have joined, the organizer can lock the meeting for additional security.
Avoid posting conference call links on public forums or social media. Instead, send the links directly to participants via secure communication channels.
Enable encryption to ensure that data exchanged during the meeting is protected from eavesdropping.
Limit screen sharing to only hosts or authorized participants. This reduces the risk of unwanted content or malicious actions.

Use the “Remove Participant” option to remove people who should not be in the conference call or who are behaving inappropriately.
Users can protect meeting passwords by using strong and unique passwords. These passwords should include a combination of letters, numbers, and special characters to make them difficult to guess.
What security settings does Zoom offer?
Zoom offers a variety of security settings to help protect your video meetings. One of the key features is the ability to create a unique password for each meeting. This password can only be shared with invitees, ensuring that only authorized people can join.
Zoom also offers the option to encrypt your video conferences. Encryption ensures that the meeting data is protected and cannot be intercepted by third parties. There is also the option of end-to-end encryption, which offers the highest level of security.

Another useful feature is the ability to lock the meeting after it starts. This way, no one else can join, even if they have the password. This setting is especially useful for preventing unwanted visitors.
Zoom also allows you to control participant permissions. The organizer can restrict participants’ capabilities, such as screen sharing, sending messages in the chat, or using the microphone and camera. These settings help maintain security during the meeting.
Finally, Zoom provides the ability to report and remove unwanted users. If someone violates the rules or behaves inappropriately, the organizer can remove them immediately and report them to Zoom's support team for further action.
What are the steps to avoid hackers in video conferences?
Use unique meeting IDs and passwords. Instead of using your personal meeting ID, create a unique ID for each conference call and protect it with a strong password.
Enable the waiting room. The waiting room allows the host to control who is trying to join the meeting and approve or deny entry.
Close the meeting after it starts. After all invitees have entered the meeting, close it to prevent unwanted people from entering.
Turn off screen sharing for participants. Only the host or co-hosts should be able to share their screen unless it's absolutely necessary for participants.
Check your settings audio and video Turn off participants' microphones and cameras when they join and only allow them to turn them on when necessary.
Avoid posting meeting links in public forums. Send links only to people who need to participate and use secure communication channels.
