Ensure sshd is not run within containers

SedangLevel 1Otomatisdocker

Deskripsi

Running an SSH server inside a container adds attack surface and complicates credential and patch management; use docker exec instead. The audit lists processes of every running container with docker top (no exec into the container) and flags those running sshd.

Cara pemeriksaan

Metode audit: Perintah shell

shell

ids=$(docker ps -q) || exit 1; bad=''; for i in $ids; do p=$(docker top "$i" -eo comm 2>/dev/null || docker top "$i") || exit 1; printf '%s\n' "$p" | grep -Eq '(^|[ /])sshd( |$)' && bad="$bad $i"; done; [ -z "$bad" ] && echo compliant || echo "sshd running in:$bad"

Output yang diharapkan: compliant

Cara perbaikan

Metode perbaikan: Panduan atau patch infrastruktur

Remove the SSH server from the image and use docker exec (or an orchestrator equivalent) for administrative access.
