Host SSH daemon, if enabled, must disable stream local forwarding

MediaNivel 1Automatizadavmware

Descripción

Disabling stream local forwarding on the SSH daemon ensures that no Unix domain sockets are forwarded, thus enforcing a security boundary. This measure aids in maintaining the integrity and confidentiality of the system. The audit reads /etc/ssh/sshd_config and requires AllowStreamLocalForwarding 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)=="allowstreamlocalforwarding" {print tolower($2); exit}' "$f")
case "$v" in '') echo 'AllowStreamLocalForwarding not set' ;; no) echo compliant ;; *) echo "AllowStreamLocalForwarding $v" ;; esac

Salida esperada: compliant

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

To remediate this recommendation, set AllowStreamLocalForwarding no, restart SSH if authorized, and verify stream-local forwarding cannot be established.
