Incident Response Strategy for CISOs
How CISOs build the response muscle: IR retainer, MSSP, SIEM, tabletop exercises, war-room readiness. Risk register, investments, and scenarios that stress IR capacity in CISO Game.
Incident response is the gap between detecting an incident and being operational again. Real CISO programs underinvest here until their first major incident; the cost of pre-incident readiness is a fraction of the cost of post-incident recovery from cold storage. CISO Game models IR capability as a posture subscore (Response 18% weight), as a team-requirement gate on every product that needs an IR Specialist, as an event consequence (you can pull capacity for war-room work), and as a R21 risk in the live register that exists specifically to track the gap between what you say you can do and what you've actually drilled.
The IR capability stack
Pre-incident: IR Retainer (on-call expert capacity), MSSP (continuous detection coverage), SIEM (the log pipeline and correlation engine), Detection Engineering (tuned rules, tested playbooks), Tabletop Exercises (cross-functional rehearsal). At-incident: war-room communication discipline, GC and CFO co-decision-making, customer-comms template ready to go. Post-incident: forensic preservation, lessons-learned, control gap remediation, and the regulatory disclosure decision tree.
Why IR retainers pay for themselves the first time they activate
Real IR retainers cost $40k–$150k/year and cap activation hours. The math is simple: a single major incident without retainer capacity runs $300k–$2M in emergency consulting plus the operational cost of the slower response. CISO Game models retainers as a Response posture contribution + an emergency-budget unlock during ransomware events. The ransomware insurance-payout mechanic (E008) specifically requires owning the IR retainer + immutable backups to drop the ransom cost.
