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

SedangLevel 1Otomatisvmware

Deskripsi

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.

Cara pemeriksaan

Metode audit: Perintah 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

Output yang diharapkan: compliant

Cara perbaikan

Metode perbaikan: Panduan atau patch infrastruktur

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