# DevSecOps Framework

## 매 한 줄
> **"매 security 가 PR 단계부터 매일 실행되는 자동 체크가 되는 것."**. DevSecOps 는 매 plan-code-build-test-release-deploy-operate-monitor 8단계 의 매 step 마다 security control 을 embed 하는 매 shift-left framework. 2026 표준: SAST + SCA + IaC scan + secret scan + DAST + RASP + supply-chain (SLSA L3) + ASPM platform.

## 매 핵심

### 매 8-Stage Embed
1. **Plan**: threat model (STRIDE), security stories.
2. **Code**: IDE plugin (Semgrep, SonarLint), pre-commit (lint-staged + secret).
3. **Build**: SBOM (Syft), reproducible build, sign (cosign).
4. **Test**: SAST (Semgrep, CodeQL), SCA (Trivy, Snyk), IaC (Checkov).
5. **Release**: provenance (SLSA), policy (OPA gatekeeper).
6. **Deploy**: admission control, signed image verify, secrets via Vault.
7. **Operate**: RASP, WAF, runtime detection (Falco).
8. **Monitor**: SIEM (Splunk), anomaly detection, incident response.

### 매 Tool Categories 2026
- **SAST**: Semgrep, CodeQL, Snyk Code.
- **SCA**: Trivy, Snyk Open Source, Dependabot.
- **DAST**: ZAP, Burp, Nuclei.
- **IaC**: Checkov, tfsec, KICS.
- **Secret scan**: gitleaks, TruffleHog.
- **Container**: Trivy, Grype.
- **K8s**: kube-bench, Falco, Kyverno.
- **ASPM**: Phoenix, Apiiro, ArmorCode — aggregate + prioritize.

### 매 응용
1. Web app secure SDLC.
2. K8s cluster hardening.
3. Cloud infra (Terraform/Pulumi) compliance.
4. Container registry policy.
5. Supply-chain integrity (SLSA L3).

## 💻 패턴

### GitHub Actions DevSecOps gate
```yaml
name: secure-pr
on: pull_request
permissions: { contents: read, security-events: write, id-token: write }
jobs:
  scan:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: gitleaks/gitleaks-action@v2     # 매 secrets
      - uses: returntocorp/semgrep-action@v1  # 매 SAST
        with: { config: 'p/owasp-top-ten p/security-audit' }
      - uses: aquasecurity/trivy-action@master # 매 SCA + container
        with: { scan-type: fs, severity: 'CRITICAL,HIGH', exit-code: 1 }
      - uses: bridgecrewio/checkov-action@master # 매 IaC
```

### Pre-commit secret scan
```yaml
# .pre-commit-config.yaml
repos:
  - repo: https://github.com/gitleaks/gitleaks
    rev: v8.18.0
    hooks: [{ id: gitleaks }]
```

### OPA admission policy (K8s)
```rego
package k8s.image
violation[{"msg": msg}] {
  input.review.object.spec.containers[_].image
  not startswith(input.review.object.spec.containers[_].image, "ghcr.io/myorg/")
  msg := "image must come from approved registry"
}
```

### Cosign verify in admission
```yaml
apiVersion: policy.sigstore.dev/v1beta1
kind: ClusterImagePolicy
spec:
  images: [{ glob: "ghcr.io/myorg/**" }]
  authorities:
    - keyless:
        identities: [{ issuer: "https://token.actions.githubusercontent.com", subject: ".*myorg/.*" }]
```

### Falco runtime detection rule
```yaml
- rule: Shell in container
  desc: Detect shell exec inside container
  condition: container.id != host and proc.name in (bash, sh, zsh)
  output: "Shell %proc.name in container=%container.name image=%container.image.repository"
  priority: WARNING
```

### SBOM + provenance attest
```bash
syft packages oci:./image.tar -o spdx-json > sbom.spdx.json
cosign attest --predicate sbom.spdx.json --type spdx ghcr.io/org/app@sha256:...
```

## 매 결정 기준
| 상황 | Tool stack |
|---|---|
| TS/Python monorepo | Semgrep + Trivy + gitleaks |
| Terraform cloud infra | Checkov + tfsec |
| K8s cluster | Falco + Kyverno + cosign |
| Compliance heavy | ASPM platform (Phoenix/Apiiro) |
| Air-gapped / regulated | Semgrep self-host + Trivy DB mirror |

**기본값**: 매 Semgrep + Trivy + gitleaks + Checkov + cosign + Falco.

## 🤖 LLM 활용
**언제**: vuln triage, false-positive filter, remediation PR draft, threat-model brainstorm.
**언제 X**: 매 actual scan — specialized engine 이 빠르고 정확.

## ❌ 안티패턴
- **Security as gate-only**: 매 alert flood 만 — fix automation 없음.
- **Tool sprawl**: 매 5개 SAST 가 noise — ASPM 으로 dedupe.
- **No baseline**: 매 legacy CVE 전체가 critical — accept + monitor.
- **Bypass culture**: 매 dev 가 `// eslint-disable security/*` — guard 무력화.

## 🧪 검증 / 중복
- Verified: NIST SSDF SP 800-218; OWASP DevSecOps maturity; SLSA v1.0; Falco docs.
- 신뢰도 A.
