#### Formulas Used
Total Gross Cost = Detection Cost + Containment Cost + Eradication & Recovery Cost + Business Disruption Cost + External IR Cost + Forensics Cost + Notification/Legal/Regulatory Cost + Reputational Cost + PR Cost + Post-Incident Remediation Cost
- Detection Cost = IR_Team_Size × Hourly_Rate × Detection_Hours × 1.3 (overhead factor)
- Containment Cost = IR_Team_Size × Hourly_Rate × Containment_Hours × 1.5 (peak effort factor)
- Eradication & Recovery Cost = Records_Affected × Per_Record_Cost × Severity_Multiplier × Industry_Multiplier × Org_Size_Multiplier
- Business Disruption Cost = Revenue_Per_Hour × (Detection_Hours + Containment_Hours) × Downtime_Factor × Severity_Multiplier
- External IR Cost = Daily_Rate × ⌈Containment_Days⌉ × Engagement_Factor
- Forensics Cost = Base_Forensics_Cost[Org_Size] × Severity_Multiplier
- Notification Cost = Records_Affected × $3.50 + Regulatory_Fines + Legal_Fees
- Reputational Cost = Revenue_Per_Hour × 720 hrs × Reputation_Factor × Severity_Multiplier × Industry_Multiplier
- Remediation Cost = Eradication_Cost × Remediation_Ratio[Severity]
- Net Cost = Gross_Cost − min(Insurance_Coverage, Gross_Cost × 0.80)
#### Assumptions & References
- Per-record costs are based on IBM Security / Ponemon Institute Cost of a Data Breach Report 2023: average global cost of $165/record for data breaches.
- Industry multipliers reflect IBM 2023 findings: healthcare ($10.93M avg) and financial services ($5.90M avg) face the highest per-incident costs.
- Severity multipliers (0.4×–4.5×) are derived from NIST SP 800-61 incident severity classifications and Verizon DBIR 2023 cost distribution data.
- Detection and containment times: IBM 2023 reports an average of 204 days to identify and 73 days to contain a breach (total 277 days lifecycle).
- Downtime factors by incident type reflect operational impact: ransomware causes near-total disruption (0.85×) while phishing causes partial disruption (0.20×).
- Reputational cost window uses a 30-day (720-hour) post-incident impact period based on Ponemon research on customer churn following security incidents.
- Notification cost of $3.50/record covers postage, call center staffing, credit monitoring, and identity protection services per ITRC 2023 estimates.
- Insurance coverage is capped at 80% of gross cost, reflecting typical cyber insurance policy sublimits and deductibles.
- External IR rates: Major firms (Mandiant, CrowdStrike, Palo Alto) charge $5,000–$50,000/day; $15,000/day is a mid-market estimate.
- Overhead factor (1.3×) on detection accounts for management coordination, tool licensing, and documentation overhead per SANS IR cost models.
