While the CSF provides a high-level governance and management framework, NIST SP 800-160 Volume 2 focuses on the engineering of cyber-resilient systems. It provides a detailed, technical approach to designing, building, and operating systems to be resilient by design, offering a "handbook" for achieving identified cyber resiliency outcomes. This publication is critical for CISOs who need to ensure resilience is embedded into the system life cycle. Not all vendors pose equal risk
