| ```python | |
| # Pseudocode for MERIT calculation | |
| def calculate_merit(scores): | |
| # Calculate dimension scores | |
| tc_score = (scores['TC1'] * 0.20 + scores['TC2'] * 0.25 + scores['TC3'] * 0.20 + | |
| scores['TC4'] * 0.15 + scores['TC5'] * 0.20) | |
| rr_score = (scores['RR1'] * 0.25 + scores['RR2'] * 0.20 + scores['RR3'] * 0.15 + | |
| scores['RR4'] * 0.20 + scores['RR5'] * 0.20) | |
| ar_score = (scores['AR1'] * 0.25 + scores['AR2'] * 0.20 + scores['AR3'] * 0.15 + | |
| scores['AR4'] * 0.20 + scores['AR5'] * 0.20) | |
| er_score = (scores['ER1'] * 0.30 + scores['ER2'] * 0.20 + scores['ER3'] * 0.25 + | |
| scores['ER4'] * 0.15 + scores['ER5'] * 0.10) | |
| de_score = (scores['DE1'] * 0.25 + scores['DE2'] * 0.20 + scores['DE3'] * 0.15 + | |
| scores['DE4'] * 0.25 + scores['DE5'] * 0.15) | |
| # Calculate Exploitation Potential (inverse of technical complexity and resource requirements) | |
| # Higher scores mean easier exploitation | |
| exploitation_potential = (10 - tc_score) * 0.5 + (10 - rr_score) * 0.5 | |
| # Calculate Access Feasibility (inverse of access requirements) | |
| # Higher scores mean more feasible access | |
| access_feasibility = 10 - ar_score | |
| # Calculate Success Likelihood (direct from exploitation reliability) | |
| success_likelihood = er_score | |
| # Calculate Stealth Factor (direct from detection evasion) | |
| stealth_factor = de_score | |
| # Calculate overall MERIT score (0-100 scale) | |
| # Higher scores indicate higher exploitation risk | |
| merit_score = ((exploitation_potential * 0.35) + (access_feasibility * 0.15) + | |
| (success_likelihood * 0.30) + (stealth_factor * 0.20)) * 10 | |
| # Determine exploitation risk category | |
| if merit_score >= 80: | |
| risk_category = "Critical Exploitation Risk" | |
| elif merit_score >= 60: | |
| risk_category = "High Exploitation Risk" | |
| elif merit_score >= 40: | |

| elif merit_score >= 20: | |
| risk_category = "Low Exploitation Risk" | |
| else: | |
| risk_category = "Minimal Exploitation Risk" | |
| return { | |
