VNC protocols can be exposed accidentally; enforce encrypted and restricted access paths.
¶ Access and Encryption Controls
- Bind VNC services to private interfaces only.
- Use SSH tunneling or TLS-enabled configurations for remote access.
- Enforce strong authentication and disable weak/no-auth modes.
¶ Session and Host Protection
- Limit who can start/listen VNC sessions.
- Restrict clipboard/file transfer features where sensitive.
- Monitor connection attempts and brute-force activity.
