OSCAL 1.0.0 Milestone 3 Release

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 plan, assessment 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 catalog, profile, 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.
