A CISO is tasked with developing an incident response capability for a rapidly growing startup. The startup has limited budget and personnel. Which of the following approaches should the CISO prioritize to establish a foundational incident response capability MOST effectively under these constraints?
- AOutsource the entire incident response function to a third-party Managed Security Service Provider (MSSP).
- BDevelop a lean incident response plan focusing on critical assets, basic detection, and clear communication procedures.
- CInvest heavily in advanced Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) tools.
- DHire a full team of dedicated incident responders and forensic analysts.
Show answer & explanationAnswer & explanation
Correct answer: B. Develop a lean incident response plan focusing on critical assets, basic detection, and clear communication procedures.
With limited budget and personnel, the most effective approach for a startup is to build a lean, foundational incident response capability. This involves identifying critical assets, establishing basic detection mechanisms (which might be simple logs or alerts), and crucially, defining clear, actionable communication procedures. This allows for a structured response to high-priority incidents without requiring significant upfront investment in complex tools or a large dedicated team.
Why the other options are wrong
- A. Outsourcing the entire function can be expensive and may not fully integrate with the startup's unique culture and assets, potentially exceeding a 'limited budget'.
- C. Advanced SIEM/SOAR tools are expensive and require significant expertise to implement and manage, which is not suitable for a limited budget/personnel scenario.
- D. Hiring a full team is a significant personnel and budget investment that contradicts the given constraints.
Lean Incident Response
An approach to incident response focusing on establishing essential capabilities with minimal resources, prioritizing critical assets and basic, actionable procedures.
- Ideal for organizations with limited budget and staff.
- Emphasizes foundational elements: identification, containment, communication.
- Scales up as resources and maturity increase.
Memory trick: Start lean, then grow mean.
