Addressing the limitations of static, compliance-based methodologies, the CRSI synthesizes the People, Process, and Technology (PPT) dimensions into a unified, network-agnostic metric. Unlike traditional binary assessments, this framework employs a dynamic maturity model applicable across diverse environments, including Information Technology (IT), Operational Technology (OT), and Critical Infrastructure Networks (CIN). The methodology integrates threat-informed weighting algorithms with qualitative control evaluations to generate a holistic resilience index. The framework’s efficacy is demonstrated through a simulated case study of a hybrid utility environment ("EnergyTech"), validated by a sensitivity analysis that confirms the model's stability against subjective weighting variations. Ultimately, the CRSI empowers organizations to diagnose capability gaps with precision, benchmark performance against industry standards, and optimize strategic investments in security infrastructure.
