Measuring and Reporting AI 紅隊 Effectiveness

# AI 紅隊 Metrics Framework
 
## Category 1: Coverage Metrics
**Question**: "Are we 測試 everything we should be?"
 
| Metric | Definition | Target |
|--------|-----------|--------|
| OWASP LLM Top 10 Coverage | % of OWASP categories tested in each engagement | 100% for standard engagements |
| 攻擊 Surface Coverage | % of enumerated components tested | >80% for standard, >95% for comprehensive |
| 測試 Case Volume | Number of unique 測試 cases per engagement | >200 for standard engagements |
| Technique Diversity | Number of distinct attack techniques used | >15 per engagement |
| Model Coverage | % of production models tested in the quarter | >90% |
 
## Category 2: 偵測 Metrics
**Question**: "Are we finding real 漏洞?"
 
| Metric | Definition | Target |
|--------|-----------|--------|
| 漏洞 Count | Total findings per engagement by severity | Track trend, not absolute number |
| 偵測 Rate | Findings per 測試 hour | Track trend |
| Novel Finding Rate | % of findings not found in previous engagements | >20% indicates evolving methodology |
| False Positive Rate | % of reported findings that were not actual 漏洞 | <5% |
| Time to First Finding | Hours from engagement start to first Critical/High finding | <4 hours |
 
## Category 3: Remediation Metrics
**Question**: "Are we driving actual 安全 improvement?"
 
| Metric | Definition | Target |
|--------|-----------|--------|
| Remediation Rate | % of findings remediated within SLA | >90% for Critical, >80% for High |
| Mean Time to Remediate (MTTR) | Average days from report to fix by severity | <7 days Critical, <30 days High |
| Regression Rate | % of previously fixed findings that reappear | <5% |
| Retest Pass Rate | % of remediated findings that pass verification | >95% |
| Open Finding Age | Average age of unresolved findings | Decreasing trend |
 
## Category 4: Program Metrics
**Question**: "Is the program worth the investment?"
 
| Metric | Definition | Target |
|--------|-----------|--------|
| Cost per Finding | Total program cost / number of findings | Track trend (should stabilize) |
| 安全 Posture Score | Average model 安全 score across evaluations | Improving trend |
| Engagement Frequency | Red team engagements per quarter | Per policy |
| Tool ROI | Findings from automated tools vs. manual 測試 | Track ratio |
| Coverage Gap Closure | % of identified gaps addressed since last quarter | >50% per quarter |
