High-Level Description
Function: PROTECT (PR) Framework: NIST Cybersecurity Framework v2.0
The hardware, software (e.g., firmware, operating systems, applications), and services of physical and virtual platforms are managed consistent with the organization's risk strategy to protect their confidentiality, integrity, and availability
What to Check
- Verify Platform Security (PR.PS) Platform Security outcome is achieved
- Review documentation and evidence for Platform Security (PR.PS)
- Assess organizational maturity for PROTECT function
