Certified Information Security Manager (CISM)Incident ManagementMedium
A CISO is establishing a new incident response team. To ensure the team can effectively manage incidents of varying severity and complexity, which of the following is the MOST important organizational structure principle to implement?
- AAdopting a flexible, scalable structure that can adapt to incident scope and involve various stakeholders.
- BAssigning all incident handling responsibilities to a single, highly experienced individual.
- COutsourcing all incident detection and response functions to a managed security service provider (MSSP).
- DImplementing a rigid, hierarchical command structure with strict adherence to predefined roles.
Show answer & explanationAnswer & explanation
Correct answer: A. Adopting a flexible, scalable structure that can adapt to incident scope and involve various stakeholders.
Incident response requires adaptability. A flexible, scalable structure allows the team to expand or contract based on the incident's demands, involving necessary expertise from different departments or external parties as needed, which is crucial for managing varying complexities.
Why the other options are wrong
- B. Relying on a single individual creates a single point of failure and limits scalability.
- C. While MSSPs can augment capabilities, outsourcing all functions may reduce internal control and knowledge transfer, and doesn't address the internal organizational structure needed for effective IR management.
- D. A rigid structure can hinder effective response to complex or novel incidents that require cross-functional collaboration.
Scalable Incident Response Structure
An organizational framework for incident response that can dynamically adjust its size, scope, and resource allocation based on the severity and complexity of an ongoing incident.
- Allows for efficient resource utilization, from small to major incidents.
- Facilitates collaboration across different internal departments and external entities.
- Often incorporates principles from models like the Incident Command System (ICS).
Memory trick: Structure should bend, not break, under pressure.
