Developing Compliance Apps

About

Step-by-step guide to creating compliance apps using docker version of GovReady-Q Commpliance Server.

Create Directories for Development

We need a place to download GovReady's install script, a place for GovReady's local sqlite database, and finally a place to store our apps for local development.

These places can be any directory path. For simplicity, let's create a single directory to store the install script and sqlite database and a subdirectory for local compliance app development.

Draft blog post on Managing Compliance Snippets with OpenControl and ComplianceLib

Managing Compliance Snippets with OpenControl and ComplianceLib

Summary

This post explains how I am using OpenControl and ComplianceLib, a couple of tools from the emerging discipline of supply chain compliance documentation automation, to manage re-usable compliance documentation content applicable to multiple systems at multiple government agencies.

The post shares how the real world example of mapping the 800-53 controls to Drupal projects (e.g., plugins) was solved by documenting the controls once in a publicly available repository using the OpenControl data format and then programmatically generating customized documents private system documentation using the open source ComplianceLib software library and a bit of Python`.

Re-usable compliance content is a blessing

Re-usable, iteratively written compliance content would be a blessing. I write iteratively. I make typographical errors. Others suggest revisions. Documenting and maintaining mappings betweem system components and compliance control
