量化三大AI安全标准漏洞，揭示合规与真实风险间的巨大鸿沟。
Quantifying Security Vulnerabilities: A Metric-Driven Security Analysis of Gaps in Current AI Standards
- 构建四维指标体系评估安全风险，首次实现跨标准量化对比。
- 欧盟ALTAI攻击面最弱（AVPI=0.51），英国工具包80%高风险未解决。
- 根因分析指出流程模糊和执行指导薄弱是核心短板，适合政策制定者参考。
随着人工智能系统融入关键基础设施，现有AI治理框架中的安全缺陷亟待关注。本文对NIST AI RMF 1.0、英国数据保护风险工具包及欧盟ALTAI三项主要AI治理标准进行审计与量化分析。采用新型风险评估方法，构建四个关键指标：风险严重性指数（RSI）、攻击潜力指数（AVPI）、合规-安全差距百分比（CSGP）和根因脆弱性评分（RCVS）。分析发现三框架共存在136项安全关切。其中，NIST未能覆盖69.23%的风险；ALTAI攻击向量脆弱性最高（AVPI=0.51）；ICO工具包的合规-安全差距最大，80.00%的高风险问题未解决。根因分析显示，ALTAI流程定义不清（RCVS=0.33），而NIST与ICO均存在执行指导薄弱（RCVS=0.25）问题。研究呼吁强化可执行的安全控制机制，并提出针对性改进建议，以弥合合规与实际风险之间的差距。
原文摘要 · Abstract (English)
As AI systems integrate into critical infrastructure, security gaps in AI compliance frameworks demand urgent attention. This paper audits and quantifies security risks in three major AI governance standards: NIST AI RMF 1.0, UK's AI and Data Protection Risk Toolkit, and the EU's ALTAI. Using a novel risk assessment methodology, we develop four key metrics: Risk Severity Index (RSI), Attack Potential Index (AVPI), Compliance-Security Gap Percentage (CSGP), and Root Cause Vulnerability Score (RCVS). Our analysis identifies 136 concerns across the frameworks, exposing significant gaps. NIST fails to address 69.23 percent of identified risks, ALTAI has the highest attack vector vulnerability (AVPI = 0.51) and the ICO Toolkit has the largest compliance-security gap, with 80.00 percent of high-risk concerns remaining unresolved. Root cause analysis highlights under-defined processes (ALTAI RCVS = 033) and weak implementation guidance (NIST and ICO RCVS = 0.25) as critical weaknesses. These findings emphasize the need for stronger, enforceable security controls in AI compliance. We offer targeted recommendations to enhance security posture and bridge the gap between compliance and real-world AI risks.
