# Automated Security Audit
|
|
|
|
## Definition
|
|
|
|
Automated Security Audit 是通过 AI 自动扫描 IAM 策略、网络规则和容器漏洞，**检测安全风险并自动修复**的能力。Agentic AI 持续监控安全态势，实时执行合规修复。
|
|
|
|
## Scope
|
|
|
|
| 扫描对象 | 检测内容 | 修复动作 |
|
|
|---------|---------|---------|
|
|
| IAM Policies | 过度权限、公共访问风险 | 自动限制权限 |
|
|
| Network Rules | 开放端口、安全组配置错误 | 自动收紧规则 |
|
|
| Container Images | 已知漏洞 (CVE) | 触发重建 + 更新 |
|
|
| S3 Buckets | 公开访问、数据泄露风险 | 自动阻止公共访问 |
|
|
| Firewalls | 配置错误、入站规则过宽 | 自动修正 |
|
|
|
|
## Agentic AI Security Audit 工作流
|
|
|
|
```
|
|
1. 持续扫描 → AWS Inspector / GCP Security Command Center / Azure Defender
|
|
2. 风险评估 → CVSS 评分 + 业务影响分析
|
|
3. 自动修复 → 低风险自动修复，高风险人工审批
|
|
4. 合规验证 → SOC 2 / FedRAMP / PCI DSS 持续检查
|
|
5. 报告生成 → 安全态势仪表盘 + 合规报告
|
|
```
|
|
|
|
## 与 [[DevSecOps]] 的关系
|
|
|
|
Automated Security Audit 是 [[DevSecOps]] 实践的核心组件：
|
|
|
|
```python
|
|
DevSecOps_Pipeline = {
|
|
"Build": "SAST (Static Application Security Testing)",
|
|
"Test": "DAST (Dynamic Application Security Testing)",
|
|
"Deploy": "Container Scanning ←", # 漏洞扫描
|
|
"Monitor": "Automated Security Audit ←", # ← 本页
|
|
"Respond": "自动威胁缓解"
|
|
}
|
|
```
|
|
|
|
## 示例
|
|
|
|
> Agentic AI detects an over-permissive IAM role:
|
|
> - Role: `production-app-read-all`
|
|
> - Allows: `s3:*` on `arn:aws:s3:::customer-data-*`
|
|
> - Risk: Public access enabled on bucket
|
|
> - **AI Action**:
|
|
> - Immediately restricts bucket policy
|
|
> - Notifies DevOps team via Slack
|
|
> - Creates Jira ticket for IAM review
|
|
> - Logs audit trail for compliance
|
|
|
|
## 与合规框架的关系
|
|
|
|
| 合规框架 | Agentic AI 支持方式 |
|
|
|---------|-------------------|
|
|
| SOC 2 | 持续访问审计 + 变更记录 |
|
|
| FedRAMP | 安全配置基线检查 + 报告 |
|
|
| PCI DSS | 数据访问控制 + 加密验证 |
|
|
| ISO 27001 | 风险评估 + 修复验证 |
|
|
