OSCAL: Unstructured to Structured. Traditional risk management ultimately relies on manual correlation of a deluge of data from diverse sources. Open Security Controls Assessment Language (OSCAL) a domain specific language (DSL) by the makers of 800-53 to the rescue.
Unfortunately, the number of security controls needed to adequately cover modern systems means simple data correlation can take hundreds of man hours. Fortunately, NIST in partnership with FedRAMP has developed Open Security Controls Assessment Language (OSCAL) a standardized, structured, and machine-readable format for describing security controls, their implementation, and assessment1.
Here are some key points about OSCAL:
- Machine-Readable Formats: OSCAL provides formats expressed in XML, JSON, and YAML. These formats allow for consistent, machine-readable representations of control catalogs, control baselines, system security plans, and assessment plans and results.
- Control-Based Approach: OSCAL focuses on control-based risk management. It allows you to easily access control information from security and privacy control catalogs, establish and share machine-readable control baselines, and maintain up-to-date information about how controls are implemented in your systems.
- Data-Centric Transition: OSCAL shifts away from legacy approaches (such as Word and Excel documents) to a data-centric model. By using common data standards like XML and JSON, OSCAL streamlines security plan generation and management.
- Extensible Architecture: OSCAL’s extensible architecture enables expressing security controls in both machine and human-readable formats. This flexibility allows organizations to adapt and customize their compliance processes.
- Integration and Automation: OSCAL supports tool developers by providing APIs and a standards-based foundation for next-generation compliance tools. Automation benefits include resource-intensive process automation and efficient monitoring of system control implementation effectiveness.
Why OSCAL Matters?
- Consistency: OSCAL facilitates consistent representation of security controls across different systems and organizations.
- Efficiency: By facilitating automation via structured data, OSCAL reduces manual effort and accelerates compliance assessments.
- Interoperability: OSCAL’s machine-readable formats facilitate information exchange and interoperability between tools and systems.
- Compliance Confidence: Organizations gain confidence in their compliance posture through accurate, up-to-date control information.
OSCAL adoption will be a game changer to automated security compliance, simplifying complex requirements and enhancing risk management practices. Whether you’re a compliance professional or a developer, understanding OSCAL can empower you to navigate the evolving landscape of cybersecurity standards and regulations.
Remember, OSCAL isn’t just an acronym—it’s a game-changer in the world of security risk management! 🚀🔒
