Host SSH daemon, if enabled, must display the system login banner before granting access

SedangLevel 1Otomatisvmware

Deskripsi

Implementing a system login banner before granting SSH access ensures that crucial information or notices are conveyed to users attempting to login. The banner text is set through the host's Config.Etc.Issue advanced parameter. The audit reads /etc/ssh/sshd_config and requires a Banner directive pointing to a non-empty file. Runs in the ESXi Shell (busybox sh) as root.

Cara pemeriksaan

Metode audit: Perintah shell

shell

f=/etc/ssh/sshd_config; [ -r "$f" ] || exit 1
b=$(awk 'tolower($1)=="banner" {print $2; exit}' "$f")
case "$b" in ''|none) echo 'no SSH Banner configured'; exit 1 ;; esac
[ -s "$b" ] && echo compliant || echo "banner file $b is missing or empty"

Output yang diharapkan: compliant

Cara perbaikan

Metode perbaikan: Panduan atau patch infrastruktur

To remediate this recommendation, configure the approved SSH banner file and Banner directive. Restart SSH only if enabled/authorized and confirm the banner appears before authentication.
