This InSpec compliance profile implement the CIS Docker 1.13.0 Benchmark in an automated way to provide security best-practice tests around Docker daemon and containers in a production environment.
InSpec is an open-source run-time framework and rule language used to specify compliance, security, and policy requirements for testing any node in your infrastructure.
We use a yml attribute file to steer the configuration, the following options are available:
trusted_user: vagrant
define trusted user to control Docker daemon.authorization_plugin: authz-broker
define authorization plugin to manage access to Docker daemon.log_driver: syslog
define preferable way to store logs.log_opts: /syslog-address/
define Docker daemon log-opts.registry_cert_path: /etc/docker/certs.d
directory contains various Docker registry directories.registry_name: /etc/docker/certs.d/registry_hostname:port
directory contain certificate certain Docker registry.registry_ca_file: /etc/docker/certs.d/registry_hostname:port/ca.crt
certificate file for a certain Docker registry certificate files.container_user: vagrant
define user within containers.app_armor_profile: docker-default
define apparmor profile for Docker containers.selinux_profile: /label\:level\:s0-s0\:c1023/
define SELinux profile for Docker containers.container_capadd: null
define needed capabilities for containers. example: container_capadd: NET_ADMIN,SYS_ADMIN
managable_container_number: 25
keep number of containers on a host to a manageable total.daemon_tlscacert : /etc/docker/ssl/ca.pem
configure the certificate authority.daemon_tlscert: /etc/docker/ssl/server_cert.pem
configure the server certificate.daemon_tlskey: /etc/docker/ssl/server_key.pem
configure the server key.swarm_mode: inactive
configure the swarm mode.swarm_max_manager_nodes: 3
configure the maximum number of swarm leaders.swarm_port: 2377
configure the swarm port.benchmark_version
to execute also the old controls from previous benchmarks, e.g. set it to 1.12.0 to execute also the tests from cis-benchmark-1.12.0 (which is the default).These settings can be overridden using an attributes file (e.g. --attrs
InSpec makes it easy to run your tests wherever you need. More options listed here: InSpec cli
# run profile locally
$ git clone https://github.com/dev-sec/cis-docker-benchmark
$ inspec exec cis-docker-benchmark
# run profile locally and directly from Github
$ inspec exec https://github.com/dev-sec/cis-docker-benchmark
# run profile on remote host via SSH
inspec exec cis-docker-benchmark -t ssh://user@hostname -i /path/to/key
# run profile on remote host via SSH with sudo
inspec exec cis-docker-benchmark -t ssh://user@hostname -i /path/to/key --sudo
# run profile on remote host via SSH with sudo and define attribute value
inspec exec cis-docker-benchmark --attrs sample_attributes.yml
# run profile direct from inspec supermarket
inspec supermarket exec dev-sec/cis-docker-benchmark -t ssh://user@hostname --key-files private_key --sudo
In order to verify individual controls, just provide the control ids to InSpec:
inspec exec cis-docker-benchmark --controls 'cis-docker-benchmark-1.4 cis-docker-benchmark-1.5'
