Your organization has recently undergone a merger, and as the CISO, you are tasked with aligning security policies and risk management practices across both companies. You discover that one company uses a risk tolerance model based on quantitative assessments, while the other relies on qualitative risk matrices. You must produce a combined risk register and recommend a unified risk strategy. Senior leadership is pressing for a decision that allows consistent prioritization of risks across business units. What should you do first? A. Adopt the qualitative risk model from the second company for simplicity and faster implementation. B. Implement the quantitative model to maintain accuracy and support insurance negotiations. C. Conduct a business impact analysis (BIA) to inform which model best supports the new organization. D. Merge the two models to balance simplicity and rigor without needing further analysis.
