Host SSH daemon, if enabled, must not permit tunnels

SrednjaNivo 1Automatskavmware

Opis

Preventing tunnel creation in the SSH daemon is a security measure aimed at thwarting unauthorized network tunneling through the host. This control, when enforced, helps mitigate the risks associated with potential data exfiltration or unauthorized network access that could occur via SSH tunnels. The audit reads /etc/ssh/sshd_config and requires PermitTunnel no (unset = OpenSSH default no). Runs in the ESXi Shell (busybox sh) as root.

Kako se proverava

Metod provere: Komanda ljuske

shell

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

Očekivani izlaz: compliant

Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

To remediate this recommendation, set PermitTunnel no, restart SSH if authorized, and verify SSH tunnel devices cannot be created.
