Security review

✓ Passed

No issues found. Passed automated security review. · v0.1.0 How review works →

  • Prompt-injection patterns
  • Secret / credential exfiltration
  • Dangerous shell & filesystem operations
  • Untrusted network calls
  • Known-malicious package signatures

What it can access

  • Network access No
  • Filesystem access No
  • Shell / process execution No
  • Environment & secrets No
  • Dynamic code execution No

From automated source analysis of v0.1.0. “Used” means the capability is present in the source — more access means more to trust, not that it’s unsafe.

Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

云原生与供应链安全

> 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](references/container-and-k8s.md) | 容器逃逸、RBAC、PSS、NetworkPolicy、Service Mesh、Admission | | 软件供应链 | [supply-chain](references/supply-chain.md) | SLSA、Sigstore、SBOM、CI/CD OIDC、attestation、VEX | | 云 IAM 与 Secrets | [cloud-iam-and-secrets](references/cloud-iam-and-secrets.md) | 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

  1. 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: *
  2. 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。
  3. 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。
  4. 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。
  5. Defense in depth — 镜像扫描 + admission policy + runtime detection + network policy + audit log,单层失守不致命。
  6. OIDC over long-lived tokens — CI 到云、Pod 到云、Service 到 Service 一律 federated identity,废弃 access key。
  7. Provenance is non-negotiable — 不知道来源的二进制不上生产;SLSA L3+ 是目标线。
  8. 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 ` / AKIA` 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
