HITRUST CSF’s risk-based levels were adapted from NIST SP 800-53, which organizes controls into baseline categories based on impact levels: low, moderate, and high. Similarly, HITRUST assigns requirement statements across multiple implementation levels (Level 1, Level 2, and Level 3) depending on organizational, technical, and regulatory risk factors. This approach ensures scalability, so smaller organizations or lower-risk environments face fewer requirements, while larger, high-risk entities face more. HITRUST harmonized this concept with mappings to other frameworks (ISO, HIPAA, PCI-DSS), but the structure of escalating control rigor by risk exposure is directly derived from NIST’s model. This alignment reinforces HITRUST’s credibility as a risk-based framework consistent with widely accepted standards.
