云原生与供应链安全

> 判断先于执行:决定「是否做 / 选什么 / 如何取舍」(栈、方案、架构、权衡)前,先读领域判断内核 skills/_kernel/security/SKILL.md——它管 judgment,本秘典管 execution;冲突时以内核判断为准。

> 默认怀疑一切外来字节:镜像、依赖、IaC 模块、CI runner、IAM trust。能签就签,能锁就锁,能最小就最小。

路由

| 意图 | 秘典 | 核心 |

|------|------|------|

| 容器/K8s 加固 | container-and-k8s | 容器逃逸、RBAC、PSS、NetworkPolicy、Service Mesh、Admission |

| 软件供应链 | supply-chain | SLSA、Sigstore、SBOM、CI/CD OIDC、attestation、VEX |

| 云 IAM 与 Secrets | cloud-iam-and-secrets | IAM 反模式、AssumeRole、Vault、KMS、IaC、Workload Identity |

何时使用

| 场景 | 用本 skill | 不用 |

|------|-----------|------|

| K8s manifest / Helm chart 安全审查 | ✅ | — |

| CI/CD pipeline (GitHub Actions / GitLab CI) 加固 | ✅ | — |

| Terraform / Pulumi / CloudFormation 评审 | ✅ | — |

| AWS/GCP/Azure IAM policy 审查 | ✅ | — |

| 镜像扫描与签名链路设计 | ✅ | — |

| 应用层 Web/API 漏洞 (SQLi/XSS/SSRF) | — | 用 securing-systems |

| 红队 C2/横移/免杀 | — | 用 securing-systems/red-team |

| 集群部署/Helm 模板编写 (非安全视角) | — | 用 provisioning-infrastructure |

| 一般架构设计与权衡 | — | 用 designing-architectures |

通用铁律

  • Least privilege by default — 任何 Role/IAM/SA/Token 起手就是空集合,按需求逐项添加,禁通配 *Action: *
  • Immutable infrastructure — 镜像用 digest 不用 tag,IaC state 不允许人工 drift,部署后只重建不改造。
  • Sign everything, verify everywhere — 镜像、artifact、commit、SBOM 必须签名;准入控制必须 verify,否则等于没签。
  • Secrets never in plaintext — 不进 git、不进 env file、不进 ConfigMap、不进 Terraform state;Vault/Secret Manager + 短期凭证。
  • Defense in depth — 镜像扫描 + admission policy + runtime detection + network policy + audit log,单层失守不致命。
  • OIDC over long-lived tokens — CI 到云、Pod 到云、Service 到 Service 一律 federated identity,废弃 access key。
  • Provenance is non-negotiable — 不知道来源的二进制不上生产;SLSA L3+ 是目标线。
  • Zero trust east-west — 内网即外网,mTLS 默认开启,NetworkPolicy 默认拒绝。

执行链

审查:清单 → 威胁建模 → 配置对照 → 风险分级 → 修复 PR → 验证回归
应急:定位失陷面 → 撤凭证 → 隔离工作负载 → 取证镜像 → 根因 → 加固准入

优先级红线

| 红线 | 立即处置 |

|------|---------|

| Secrets 已进 git history | 撤销凭证 → rewrite history → 通报 |

| 公网暴露 K8s API server | 关闭 → IP 白名单 → 审计访问日志 |

| privileged: true Pod 跑业务 | 拒绝准入 → 重构镜像 → PSS restricted |

| CI 用 long-lived AWS key | 切 OIDC → 撤销 key → 审计旧密钥使用 |

| Action: * IAM policy | 收敛权限 → CloudTrail 审计实际使用 |

与其他 skill 联动

  • 应用层漏洞(SQLi、XSS、反序列化、代码污点)→ securing-systems/code-auditpentest
  • 红队对抗与 C2 → securing-systems/red-team
  • SOC 检测/Sigma/IR → securing-systems/blue-team
  • 集群与 Helm/GitOps 部署(非安全视角)→ provisioning-infrastructure
  • API/认证架构设计 → designing-architectures/security-arch
  • DevOps 流水线工程实践 → automating-devops

输出约束

  • 反例使用 RFC 5737 (192.0.2.0/24198.51.100.0/24) 或 example.com
  • 凭证一律 <REDACTED> / AKIA<EXAMPLE> 占位
  • 发现真实泄漏只报位置和处置流程,不复述完整值
  • 修复方案必须给出最小权限策略片段,不抛"参考最佳实践"了事

How to use it

Copy the folder

Take telagod/securing-cloud-and-supply-chain from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
