Below are ways to ensure your webcam is secure:

1. Ensure your operating system is up-to-date and running the latest software.
2. Keep all security measures and software (such as antivirus) up-to-date.
3. If you have an external webcam, plug it in only when you are using it.
4. Cover your webcam with a sticker or a post-it when not in use.
5. Regularly check for any software that a hacker may have installed, such as camera surveillance software, from within your operating system.
