Risk Scoring Algorithm

The unified risk scoring system combines multiple factors:

risk_score = (
    base_score *
    confidence_multiplier *
    frequency_multiplier *
    complexity_multiplier *
    reputation_multiplier *
    type_weight
)

• Base Score: Initial confidence from detection engine
• Frequency: Attack recurrence from same IP
• Complexity: Payload sophistication analysis
• Reputation: Historical IP behavior tracking
• Type Weight: Attack type severity multiplier
