Profile Applicability: Level 1 - Docker - Linux
Assessment Status: Manual
The Docker daemon starts a userland proxy service for port forwarding whenever a port is exposed. Where hairpin NAT is available, this service is generally superfluous to requirements and can be disabled.
The Docker engine provides two mechanisms for forwarding ports from the host to containers, hairpin NAT, and the use of a userland proxy. In most circumstances, the hairpin NAT mode is preferred as it improves performance and makes use of native Linux iptables functionality instead of using an additional component.
Where hairpin NAT is available, the userland proxy should be disabled on startup to reduce the attack surface of the installation.
Some systems with older Linux kernels may not be able to support hairpin NAT and therefore require the userland proxy service. Also, some networking setups can be impacted by the removal of the userland proxy.
To confirm this setting, you should review the dockerd start-up options and any settings in /etc/docker/daemon.json.
To review the dockerd startup options, use:
ps -ef | grep dockerd
Ensure that the --userland-proxy parameter is set to false.
The contents of /etc/docker/daemon.json should also be reviewed for this setting.
You should run the Docker daemon as below:
dockerd --userland-proxy=false
By default, the userland proxy is enabled.
