Key Concepts

• Target: The foundational element representing a single NIST RMF profile throughout its lifecycle. It serves as a shared table between GRC products and Use Case Accelerators, encapsulating attributes specific to RMF assessment.
• Security Objectives (CIA Triad): Each Target has defined objectives for Confidentiality, Integrity, and Availability. These objectives are classified as High, Moderate, or Low and drive the selection of appropriate security controls.
  • Confidentiality: Protecting information access and disclosure to maintain privacy and proprietary data.
  • Integrity: Guarding against unauthorized changes to ensure authenticity and non-repudiation.
  • Availability: Ensuring timely and reliable access to information.
• Baseline Controls: Predefined sets of NIST security controls categorized by impact level (High, Moderate, Low) that mitigate risks and satisfy security requirements when effectively implemented.
• Impact Analysis: The process of assessing how changes to a Target or its environment affect its security posture. The highest impact level among the CIA objectives determines the control impact level applied to the Target.
• Assurance Controls: Controls that enhance security strength and confidence in the Target’s functionality, helping to meet security requirements and reduce risk.
• Common Controls: Controls shared and inherited by multiple Targets, promoting efficiency in control implementation.
• Compensating Controls: Alternative controls used instead of baseline controls that provide equivalent protection.
• Supplemental Controls: Additional controls implemented to address specific risk management needs beyond baseline requirements.
• Tailoring: The process of customizing the baseline controls based on Target scoping, compensating control specification, and organization-defined parameters to ensure appropriate risk management alignment.

Practical Implications for ServiceNow Customers

ServiceNow customers leveraging the NIST RMF Use Case Accelerator or transitioning to Continuous Authorization Monitoring can expect a structured approach to managing security controls mapped to NIST standards. Understanding the Target concept and CIA-based impact analysis enables precise control selection and risk mitigation tailored to organizational needs. The ability to apply common, compensating, and supplemental controls, along with tailoring, provides flexibility to meet unique compliance requirements while maintaining alignment with NIST guidelines.
