IoEH = (C × 0.25) + (F × 0.20) + (D × 0.25) + (R × 0.15) + (M × 0.15) Each sub-index is normalized to a 0–100 scale. Weights can be adjusted based on industry risk profile (e.g., finance may increase R’s weight). Measures what percentage of the attack surface is tested within a given period (e.g., 12 months).
| Metric | Weight | Formula | |--------|--------|---------| | Critical findings closed within SLA (e.g., 7 days) | 50 | (closed on time / total critical) × 50 | | High findings closed within SLA (e.g., 30 days) | 30 | (closed on time / total high) × 30 | | Reopened findings rate | -20 | subtract (reopened / total closed) × 20 | indexof ethical hacking
D = Average depth score across all tested asset categories A unique addition: ethical hacking is useless without fixing findings. IoEH = (C × 0
For a typical enterprise with 3 critical web apps (monthly → 80), 200 internal hosts (quarterly → 60), 50 non-critical (annually → 20). Weighted average ≈ 67 . 2.3 Depth (D) – Weight 25% The sophistication level of testing.
