# Cloud / Container / Kubernetes Security

## 适用场景

- 云元数据 SSRF(169.254.169.254 / IMDS)
- IAM 过度权限、公开存储桶、错误安全组
- Docker/containerd 逃逸路径评估
- Kubernetes RBAC、Secrets、Admission、供应链镜像
- 容器镜像漏洞(可联动 `supply-chain-security/`)

## 工作流

### Phase 1 — 身份与边界

```text
□ 当前身份:云 AK/SK、K8s SA、节点 SSH?
□ 范围:单账号 / 单 cluster / 单 namespace
□ 网络档:authorized_target_only
```

### Phase 2 — 云控制面

```bash
# 示例(按厂商替换;MUST 在授权账号内)
aws sts get-caller-identity
aws s3 ls
# Azure / GCP 对应 identity 命令
```

```text
□ 公开桶 / 错误 ACL
□ 元数据:IMDSv1 vs v2;SSRF 链
□ 角色可扮演(PassRole)与横向
```

### Phase 3 — 容器

```text
□ 是否 privileged / hostPath / hostNetwork
□ capabilities(SYS_ADMIN 等)
□ 可写宿主机路径 → 逃逸候选
□ 镜像历史与已知 CVE → Trivy
```

### Phase 4 — Kubernetes

```bash
kubectl auth can-i --list
kubectl get pods,secrets,svc -A
kubectl get clusterrolebindings
```

```text
□ SA token 挂载与权限
□ 危险 admission webhook 缺失
□ etcd / dashboard 暴露
□ 网络策略是否默认放行
```
