Host SSH daemon, if enabled, must not allow use of gateway ports

MediaNivel 1Automatizadavmware

Descripción

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. The audit reads /etc/ssh/sshd_config and requires GatewayPorts no (unset = OpenSSH default no). Runs in the ESXi Shell (busybox sh) as root.

Cómo se verifica

Método de auditoría: Comando de shell

shell

f=/etc/ssh/sshd_config; [ -r "$f" ] || exit 1
v=$(awk 'tolower($1)=="gatewayports" {print tolower($2); exit}' "$f")
case "$v" in '') echo compliant ;; no) echo compliant ;; *) echo "GatewayPorts $v" ;; esac

Salida esperada: compliant

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

To remediate this recommendation, set GatewayPorts no in the supported ESXi SSH configuration. Restart SSH only during an authorized maintenance/admin window and verify the effective setting.
