By mukul975. Updated August 2, 2026. Categories: System Administration.

Harden the Docker daemon (dockerd) by configuring /etc/docker/daemon.json with user namespace remapping, TLS client authentication, seccomp profiles, and CIS Docker Benchmark controls such as icc, no-new-privileges, and live-restore. Use when securing a Docker host's daemon configuration to prevent privilege escalation, container breakout, or lateral movement, or when auditing daemon settings against CIS benchmark requirements.
