Schemas

YAML schema, examples, and validators for OpenControl format. You can find the formal definitions and learn about how to do validation in the kwalify/ folder. The examples from the Glorious (Fake) Nation of Freedonia are the complete standalone example targeted at OpenControl beginners, so we recommend looking at those first.

Full project examples

Components

Components represent individual parts of an application or organizational policy that deal with specific security requirements. For example, in the AWS compliance documentation the EC2 component deals with access control and identity management security requirements. In the Cloud Foundry compliance documentation, the UAA the Cloud Controller components deal with those requirements. In a straightforward Django-based application, for example, Django would be the component that deals with access control and identity management. As a developer building an SSP you most likely only deal with the component documentation.

Examples

Structure

name: Name of the component
key: Key of the component (defaults to the filename if not present)
documentation_complete: Manual check if the documentation is complete (for gap analysis)
schema_version: 3.0.0
references:
  - name: Name of the reference ie. EC2 website
    path: Relative path of local file or URL ie. diagrams/diagram-1.png
    type: Type of reference ie. Image, URL
  - name: Name of the reference ie. EC2 website
    path: Relative path of local file or URL ie. diagrams/diagram-1.png
    type: Type of reference ie. Image, URL
verifications:
  - key: Key of verification
    name: Name of verification
    path: Relative path of local file or URL ie. diagrams/diagram-1.png
    type: Type of reference ie. Image, URL
  - key: Key of verification
    name: Name of verification
    path: Relative path of local file or URL ie. diagrams/diagram-1.png
    type: Type of reference ie. Image, URL
satisfies:
  - standard_key: Standard Key (NIST-800-53)
    control_key: Control Key (CM-2)
    narrative:
      - key: The optional key that represents a particular section of the control. If the key is not specified, assume the string in the following text represents the entire control
        text: The narrative text for the particular section / entire control if there is no key specified
    implementation_statuses:
      - Used for gap analysis, can only be one of the following:
      - partial
      - planned
      - complete
      - none
    control_origins:
      - shared
      - inherited
      - Other text representing the control origination.
    parameters:
     - key: "The key for a particular parameter of the specific control"
       text: "The parameter text for a particular parameter of a specific control"
    covered_by:
      - verification_key: The specific verification ID that the reference links, no component or system is needed for internal references
      - system_key: System name of the verification (can link to other systems / components)
        component_key: System name of the verification (can link to other systems / components)
        verification_key: The specific verification ID that the reference links to

Validation

kwalify -f kwalify/component/v3.0.0.yaml examples/component_v3.0.0.yaml
# OR
pykwalify -s kwalify/component/v3.0.0.yaml -d examples/component_v3.0.0.yaml

Standards

A standard is a list composed of individual security requirements called controls.

Examples

# nist-800-53.yaml
standards:
  C-2:
    name: User Access
    description: There is an affordance for managing access by...

# PCI.yaml
standards:
  Regulation-6:
    name: User Access PCI
    description: There is an affordance for managing access by...

Certifications

Since standards can have thousands of security requirements (aka controls), agencies like the GSA or organizations such as FedRAMP have curated a list of controls they require in order grant an IT system Authority to Operate (ATO). These are also known as "baselines". The GSA, for example, developed a baseline called the Lightweight ATO (LATO), which uses only 24 controls.

Example

# Fisma.yaml
standards:
  NIST-800-53:
    C-2:
    C-3:
  PCI:
    6:

Systems

The opencontrol.yaml file defines an application's documentation configuration settings.

Structure

schema_version: "1.0.0" # 1.0.0 is the current opencontrol.yaml schema version
name: Project_Name # Name of the project
metadata:
  description: "A description of the system"

  - ./cert-1.yaml
standards: # An optional list of standards for more information visit: https://github.com/opencontrol/schemas

dependencies:
  certifications: # An optional list of certifications stored remotely

      revision: master
  systems:  # An optional list of repos that contain an opencontrol.yaml stored remotely
    - url: https://github.com/18F/cg-compliance

  standards:   # An optional list of remote repos containing standards info that contain an opencontrol.yaml
    - url: https://github.com/opencontrol/NIST-800-53-Standards
      revision: master

For version control systems, a option key contextdir can be specified to handle multiple opencontrol content directories in a single repository. For example:

dependencies:
    - url: https://github.com/organization/repository
      contextdir: subdirectory_in_repository
      revision: branch

Validation
