InSpec Profile to validate the secure configuration of nginx-baseline, adapted from DISA's Apache 2.2 Server STIG checks.
Container-Ready: Profile updated to adapt checks when the running against a containerized instance of nginx, based on reference container: https://ironbank.dso.mil/repomap/opensource/nginx
It is intended and recommended that InSpec run this profile from a "runner" host (such as a DevOps orchestration server, an administrative management system, or a developer's workstation/laptop) against the target remotely over ssh.
The latest versions and installation options are available at the InSpec site.
The following inputs must be configured in an inputs ".yml" file for the profile to run correctly for your specific environment. More information about InSpec inputs can be found in the InSpec Profile Documentation.

(Git is required to clone the InSpec profile using the instructions below. Git can be downloaded from the Git site.)
When the "runner" host uses this profile baseline for the first time, follow these steps:
mkdir profiles
cd profiles
git clone https://github.com/mitre/nginx-baseline
inspec archive nginx-baseline
inspec exec <name of generated archive file> -t ssh://TARGET_USERNAME:TARGET_PASSWORD@TARGET_IP:TARGET_PORT --sudo --sudo-password=<SUDO_PASSWORD_IF_REQUIRED> --input-file <path_to_your_input_file/name_of_your_input_file.yml> --reporter json:<path_to_your_output_file/name_of_your_output_file.json>
(execute using the same methods discussed above, substituting the name of the generated archive in place of "https://github.com/mitre/nginx-baseline/archive/master.tar.gz")
For every successive run, follow these steps to always have the latest version of this baseline:
cd nginx-baseline
git pull
cd ..
inspec archive nginx-baseline --overwrite
inspec exec <name of generated archive file> -t ssh://TARGET_USERNAME:TARGET_PASSWORD@TARGET_IP:TARGET_PORT --sudo --sudo-password=<SUDO_PASSWORD_IF_REQUIRED> --input-file <path_to_your_input_file/name_of_your_input_file.yml> --reporter json:<path_to_your_output_file/name_of_your_output_file.json>
(execute using the same methods discussed above, substituting the name of the generated archive in place of "https://github.com/mitre/nginx-baseline/archive/master.tar.gz")
The JSON results output file can be loaded into heimdall-lite for a user-interactive, graphical view of the InSpec results.
The JSON InSpec results file may also be loaded into a full heimdall server, allowing for additional functionality such as to store and compare multiple profile runs.
