OSCAL 1.0.0 Milestone 3 Release
June 16, 2020

NIST is pleased to announce the release of OSCAL 1.0.0 Milestone 3. This is the third official milestone pre-release of OSCAL and marks the last pre-release milestone for OSCAL v1. At this point we have drafts of all the models we intended to produce for OSCAL v1 and will now start working towards producing a full initial release of OSCAL v1, which will be v1.0.0.

This release contains:

  • A new component definition model, which allows for the definition of a set of components that each provide a description of the controls supported by a specific implementation of a hardware, software, or service; or by a given policy, process, procedure, or compliance artifact (e.g., FIPS 140-2 validation).
  • Creation of draft models for the assessment and assessment result layers. Drafts of the assessment planassessment results, and plan of action and milestones (POA&M) models were created. These drafts were slated for the OSCAL v2 release cycle and are being released early as drafts ahead of schedule.
  • Updated stable versions of the OSCAL catalogprofile, and system security plan (SSP) models, along with associated XML and JSON schemas. These changes were made based on all of the feedback we received from the OSCAL community. The NIST OSCAL team is very thankful for all of the great feedback we have received.
  • New OSCAL content in XML, JSON, and YAML formats for the draft NIST SP 800-53 revision 5 catalog.
  • Updated content in OSCAL XML, JSON, and YAML formats for the NIST SP 800-53 revision 4 catalog, and for the three NIST and four FedRAMP baselines.
  • Provides tools to convert OSCAL catalog, profile, and SSP content between OSCAL XML and JSON formats, and to up convert content from milestone 2 to milestone 3.

To download this release, click on "Assets" on our OSCAL release page, and download either the .zip or the .tar.bz2 bundle. These bundles contain the resources described above. There are also release notes containing a summary of changes in this and previous releases.

The OSCAL team will continue the development of OSCAL focusing our full attention on providing a more complete set of documentation for all the OSCAL layers and models, creating more examples, and providing a diverse set of tutorials. We will continue to collect feedback from the community on the OSCAL models. We are also seeking tool developers, vendors, and service providers that would like to implement the OSCAL models in commercial and open source offerings. To provide feedback, to ask questions, or to let us know about an OSCAL implementation you are working on, please email the NIST OSCAL team at oscal@nist.gov. You can also post publicly to the OSCAL development list: oscal-dev@list.nist.gov.

Also, the FedRAMP PMO has released a blog and a short video that discusses high-level OSCAL goals, applications, and how to use the FedRAMP OSCAL SSP template and other resources. It is important to note that the FedRAMP’s OSCAL SSP Template and Guidance are based of the previous milestone release of OSCAL, Milestone 2 while NIST’s latest OSCAL release is Milestone 3. 

Please find instructions for joining the OSCAL development and update lists on our contacts page.
