# Docker Security Benchmark Checker
|
||||
|
||||
The Docker Security Benchmark Checker 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 the benchmark
|
||||
|
||||
We packaged this benchmark 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 diogomonica/docker-security-benchmark
|
||||
```
|
||||
|
||||
## Building the benchmark
|
||||
|
||||
If you wish to build and run this container yourself, you can follow the following steps:
|
||||
|
||||
```
|
||||
# git clone https://github.com/diogomonica/docker-security-benchmark.git
|
||||
# cd docker-security-benchmark; docker build -t docker-security-benchmark .
|
||||
# docker run 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 docker-security-benchmark
|
||||
```
|
||||
|
||||
Also, this script can also be simply run from your base host by running:
|
||||
|
||||
```
|
||||
# git clone https://github.com/diogomonica/docker-security-benchmark.git
|
||||
# cd docker-security-benchmark; sh docker_security_benchmark.sh
|
||||
```
|
||||
|
||||
This script was build to be POSIX 2004 compliant, so it should be portable across any Unix platform.
