All SSH traffic is encrypted and secured. SSH provides password or public-key based authentication and encrypts connections between two network endpoints.

To make it more secure do the followings:
1. Disable "Root Login"
2. Use TCP port 33001 instead of port 22
3. disable all kinds of SSH tunneling
4. Always update all public and private key authentication

Few best practices Securing Linux SSH Server Connections

  • Disable Root User Logins.
  • Modifying the Default Port...
  • Access is denied to users with blank passwords.
  • Limit the number of login attempts.
  • Using SSH Version 2. ...
  • Disabling TCP Port Forwarding and X11 Port Forwarding.
  • Connecting With an SSH Key...
  • IP Limitations for SSH Connections


also we need to configure access key that will help to secure connection in the best possible way

The best way to secure SSH Server connections on Linux is to use public/private key authentication and disable password authentication. Additionally, you should use strong passwords, limit root access, and limit the number of connection attempts. Configure the SSH server to use a non-standard port, and use a firewall to restrict access to only authorized IPs. Lastly, use two-factor authentication and regularly monitor the system for any suspicious activity.
