위험 관리 (Risk Management)

Risk management is a systematic, iterative process of identifying, analyzing, prioritizing, treating, monitoring, and communicating risks to enable informed decision-making. It spans IT risk management, enterprise risk management (ERM), and financial risk management, and is guided by formal frameworks such as COSO ERM and ISO 31000. The process begins with risk identification, asset inventory, and threat modeling to collect risk events and loss scenarios. Risk analysis estimates likelihood and impact using qualitative scales, quantitative models, or hybrid approaches. Risk evaluation compares results against risk appetite, tolerance, and thresholds to determine risk treatment priorities. Risk treatment encompasses avoidance, reduction, transfer, or acceptance, with residual risk defined as the risk remaining after controls. Risk monitoring and review ensure controls stay effective as conditions change, and reporting communicates status to governance bodies. Practical IT risk management emphasizes cyber risk, data protection, third‑party risk, and system resilience. A robust program uses a risk register, clear ownership, objective-based risk appetite, metrics, and automated data feeds to maintain up-to-date risk information. Governance sets policy, allocates resources, and integrates risk management into strategic planning. Quantitative methods (e.g., Monte Carlo simulations, value-at-risk, fault tree analysis) quantify uncertainty, while qualitative methods (rating scales) provide timely input when data are scarce. Aligning risk treatment with business objectives supports value creation, compliance, and sustainability. Finally, emerging risks require horizon scanning, scenario planning, and periodic reassessment of risk appetite to reflect changing external and internal conditions.
