SSH Best Practices

Here are some best practices for using SSH securely:

Use Strong Passwords: Always use a strong, unique password for your SSH accounts. Avoid common passwords and consider using a password manager to generate and store your passwords.
Enable Two-Factor Authentication: Two-factor authentication adds an extra layer of security by requiring a second form of verification, such as a code sent to your phone.
Keep SSH Software Updated: Regularly update your SSH software to ensure you have the latest security patches.
Use Key-Based Authentication: Instead of passwords, use SSH keys for authentication. This is more secure and can be easier to manage.
Limit Access: Only grant SSH access to trusted users and systems. Use firewall rules to restrict access to your SSH server.
Use Secure SSH Versions: Avoid using older, unsupported SSH versions, as they may contain security vulnerabilities.
Use Public Key Servers: Store your SSH public keys on a public key server to make it easier for others to contact you securely.
Backup SSH Keys: Regularly backup your SSH keys to prevent loss of access to your accounts.
Monitor SSH Access: Keep an eye on your SSH access logs for any suspicious activity.
Use SSH Configuration Files: Configure SSH with a ~/.ssh/config file to set up aliases, control permissions, and more.
