Information
When enabled, the SSH daemon on the host should have the gateway ports feature disabled to prevent remote hosts from forwarding connections. This is a hardening measure to ensure that the SSH service is securely configured against potential forwarding misuses.
Disabling gateway ports is a preventative measure to avoid unauthorized forwarding by remote hosts, thus enhancing the security posture of the system. It is a prudent step in minimizing the attack surface associated with SSH service.
Solution
Impact:
There are no noted functional impacts associated with this control. It is a proactive security measure designed to prevent potential misuse of SSH service forwarding capabilities, without affecting the normal operation of the host.
