A multinational corporation is developing a global incident response strategy. The CISO proposes implementing a centralized incident response team to handle all incidents across all regions. However, regional business leaders express concerns about local autonomy and unique regulatory landscapes. Which of the following is the MOST appropriate strategy for the CISO to address these concerns while maintaining overall control and consistency?
- AMandate the centralized model, emphasizing efficiency and cost savings.
- BAdopt a fully decentralized model, empowering each region with full autonomy.
- CImplement a hybrid (federated) model with central oversight and regional incident response capabilities.
- DOutsource all incident response activities to a global managed security service provider (MSSP).
Show answer & explanationAnswer & explanation
Correct answer: C. Implement a hybrid (federated) model with central oversight and regional incident response capabilities.
A hybrid or federated model allows for central coordination, standardization, and intelligence sharing, while also empowering regional teams to handle local incidents, adapt to specific regulatory requirements, and leverage local expertise. This balances global consistency with regional autonomy.
Why the other options are wrong
- A. Mandating a centralized model ignores valid concerns about local regulatory differences and responsiveness, leading to resistance.
- B. A fully decentralized model risks inconsistency, lack of shared intelligence, and potential duplication of efforts, undermining overall security posture.
- D. Outsourcing can be part of a strategy but doesn't inherently resolve the tension between centralization and regional autonomy for internal response capabilities.
Federated Incident Response Model
An incident response structure that combines elements of centralized and decentralized models, providing central coordination and standards while allowing regional or local teams autonomy for specific incidents.
- Balances global consistency with local responsiveness.
- Facilitates shared intelligence and resources.
- Ideal for multinational organizations with diverse regulatory requirements.
