Workaround: * Minimize network exposure to ensure the device is not accessible from the Internet. * Limit SSH access to trusted IP addresses and networks using firewall rules or TCP wrappers. * Implement IDS or Intrusion Prevention System (IPS) to detect and prevent exploitation attempts. These systems can provide an additional layer of defense by monitoring network traffic for signs of attacks.
