# Docker Bench for Security
|
|
|
|
|
|
|
|
The Docker Bench for Security is a script that checks for all the automatable tests included in the [CIS Docker 1.6 Benchmark](https://benchmarks.cisecurity.org/tools2/docker/CIS_Docker_1.6_Benchmark_v1.0.0.pdf). We are releasing this as a follow-up to our [Understanding Docker Security and Best Practices](https://blog.docker.com/2015/05/understanding-docker-security-and-best-practices/) blog post.
|
|
|
|
We are making this available as an open-source utility so the Docker community can have an easy way to self-assess their hosts and docker containers against this benchmark.
|
|
|
|
## Running Docker Bench for Security
|
|
|
|
We packaged docker bench as a small container for your convenience. Note that this container is being run with a *lot* of privilege -- sharing the host's filesystem, pid and network namespaces, due to portions of the benchmark applying to the running host.
|
|
|
|
The easiest way to run your hosts against the CIS Docker 1.6 benchmark is by running our pre-built container:
|
|
|
|
|
|
```
|
|
docker run -it --net host --pid host -v /var/run/docker.sock:/var/run/docker.sock \
|
|
-v /usr/lib/systemd:/usr/lib/systemd -v /etc:/etc --label docker-bench-security \
|
|
diogomonica/docker-bench-security
|
|
```
|
|
|
|
Docker bench requires Docker 1.6.2 or later in order to run, since it depends on the `--label` to exclude the current container from being inspected. If you can't upgrade to 1.6.2, I feel free to remove the `--label` flag or run the shell script locally (see below).
|
|
|
|
Additionally, there was a bug in Docker 1.6.0 that would not allow mounting `-v /dev:/dev`. If you are getting an error while accessing `resolv.conf`, please update your docker to 1.6.2.
|
|
|
|
## Building Docker Bench for Security
|
|
|
|
If you wish to build and run this container yourself, you can follow the following steps:
|
|
|
|
```
|
|
git clone https://github.com/diogomonica/docker-bench-security.git
|
|
cd docker-bench-security; docker build -t docker-bench-security .
|
|
docker run -it --net host --pid host -v /var/run/docker.sock:/var/run/docker.sock \
|
|
-v /usr/lib/systemd:/usr/lib/systemd -v /etc:/etc --label security-benchmark \
|
|
docker-bench-security
|
|
```
|
|
|
|
Also, this script can also be simply run from your base host by running:
|
|
|
|
```
|
|
git clone https://github.com/diogomonica/docker-bench-security.git
|
|
cd docker-bench-security; sh docker-bench-security.sh
|
|
```
|
|
|
|
This script was build to be POSIX 2004 compliant, so it should be portable across any Unix platform.
