Host SSH daemon, if enabled, must ignore .rhosts files

MediaNivel 1Automatizadavmware

Descripción

Ignoring .rhosts files is crucial in hardening the SSH daemon on the host, ensuring that trust relationships are explicitly defined and not implicitly accepted, thereby reducing the attack surface. The audit reads /etc/ssh/sshd_config and requires IgnoreRhosts yes (unset = OpenSSH default yes). 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)=="ignorerhosts" {print tolower($2); exit}' "$f")
case "$v" in '') echo compliant ;; yes) echo compliant ;; *) echo "IgnoreRhosts $v" ;; esac

Salida esperada: compliant

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

To remediate this recommendation, set IgnoreRhosts yes, restart SSH if authorized, and verify .rhosts-based trust is ignored.
