SSH Security: Changing Port 22 and Port Forwarding

Enhancing SSH security involves changing port 22 and managing port forwarding. Find out more here.

SSH security often emphasizes changing port 22 and disabling root login, but changing the port mainly reduces background noise. The actual security is determined by encryption algorithms and authentication methods. Port 22 only controls where the TCP handshake occurs and does not provide additional security.

SSH port forwarding introduces various risks through local, remote, and dynamic modes. Each mode presents different attack vectors and allows SSH to function as a general-purpose tunneling mechanism, necessitating careful management. Proper controls must be enforced to maintain security across all forwarding capabilities.
