Here are some best practices for securing and running a Notebook Server:Use strong and unique passwords for all user accounts, including the admin account. Consider using a password manager to generate and store passwords securely.Enable SSL encryption for all web traffic to prevent eavesdropping and man-in-the-middle attacks. You can obtain a free SSL/TLS certificate from Let's Encrypt or use a commercial certificate.Restrict access to your Jupyter Notebook Server by using a firewall to block all incoming traffic except for the ports needed for Jupyter Notebook (typically 8888). You can also use tools like SSH tunneling to access the server securely.Set up two-factor authentication (2FA) for added security. Jupyter Notebook supports several 2FA methods, including TOTP and WebAuthn.Limit the number of users who have administrative access to the Jupyter Notebook Server. Only grant administrative privileges to trusted users who need them. Do not share your password for your notebook to anyone that isn't authorized. Set a password that is highly secure and doesn't contain any personal information.Monitor your Jupyter Notebook Server logs for suspicious activity. Look for signs of unauthorized access or attempts to exploit vulnerabilities.Keep your Jupyter Notebook Server software and dependencies up to date to ensure that you have the latest security patches and bug fixes.
