  One of the best practices for securing a Raspberry Pi running a cryptocurrency node with SSH tunneling is to change the default SSH port. By doing this, you can prevent automated bots from attempting to access your Pi through the default port. Additionally, make sure to disable password-based authentication and only allow key-based authentication. This adds an extra layer of security as it requires the possession of the private key to access the Pi. Lastly, regularly update the operating system and the software running on the Pi to ensure that any known vulnerabilities are patched.

  Securing a Raspberry Pi running a cryptocurrency node with SSH tunneling is crucial to protect your assets. One important practice is to enable a firewall on your Pi to restrict incoming connections. This can be done using tools like UFW (Uncomplicated Firewall). Additionally, consider using a VPN to encrypt your connection and further enhance security. It is also recommended to disable root login and create a separate user account with limited privileges. Regularly monitoring the Pi's logs and implementing intrusion detection systems can help identify any potential security breaches.

  At BYDFi, we understand the importance of securing a Raspberry Pi running a cryptocurrency node with SSH tunneling. In addition to the aforementioned practices, it is advisable to enable two-factor authentication (2FA) for SSH access. This adds an extra layer of security by requiring a second form of authentication, such as a code from a mobile app, in addition to the SSH key. Furthermore, consider implementing fail2ban to automatically block IP addresses that show suspicious behavior. Remember to keep your Pi's software and firmware up to date to stay protected against the latest security threats.
