# AI Code Review + DevSecOps

## 📌 한 줄 통찰
> **Shift-left security**. 매 SDLC 의 early 의 SAST + AI review + human. 매 mechanical 의 AI, 매 architectural 의 human.

## 📖 핵심

### Hybrid model
- **AI**: pattern matching, syntax, known CVE.
- **Human**: business logic, architecture, novel attack.
- **Together**: 매 layer 의 different defect class.

### Shift-left phases

#### IDE (real-time)
- 매 keystroke 의 lint / type.
- Cursor / Copilot 의 inline.

#### Pre-commit (local)
- Husky + lint-staged.
- 매 dev 의 first defense.

#### PR (automated)
- CodeRabbit / Greptile.
- Snyk / Sonar SAST.
- 매 dependency check.

#### CI deep
- Container scan.
- Dependency vulnerability.
- License check.

#### Pre-deploy
- Integration security test.
- DAST (runtime).

#### Production
- WAF.
- RASP (runtime application self-protection).
- 매 alert / incident.

### 매 OWASP Top 10 (2021)
1. Broken Access Control.
2. Cryptographic Failures.
3. Injection (SQL, XSS, Command).
4. Insecure Design.
5. Security Misconfiguration.
6. Vulnerable Components.
7. Authentication Failures.
8. Software / Data Integrity.
9. Logging / Monitoring Failures.
10. SSRF.

→ 매 SAST 의 mostly cover. 매 #4 (insecure design) = human.

### Tool stack (2026)

#### IDE
- Cursor (AI-native).
- Snyk Code IDE plugin.
- GitHub Copilot Chat.

#### CI / PR
- CodeRabbit (LLM review).
- Snyk Code (SAST).
- Sonar (quality + security).
- Semgrep (custom pattern).
- GitHub Advanced Security (CodeQL).

#### Container
- Trivy (image scan).
- Snyk Container.
- Docker Scout.

#### Dependency
- Dependabot.
- Renovate.
- Snyk Open Source.

#### Secret
- TruffleHog.
- GitGuardian.
- 매 pre-commit hook.

#### DAST
- OWASP ZAP.
- Burp Suite.

### 매 quality gate

#### PR gate
- 매 high severity 의 fail.
- 매 critical CVE 의 block.
- 매 secret 의 detection 의 block.

#### Pre-deploy gate
- 매 manual approve (high-risk).
- 매 automated test 의 pass.

### Compliance

#### SOC 2
- 매 audit log.
- 매 access control.
- 매 incident response.

#### PCI DSS (payment)
- 매 encryption.
- 매 segmentation.

#### GDPR (privacy)
- 매 data minimization.
- 매 consent.

#### HIPAA (health)
- 매 PHI handling.

### Vibe coding 의 specific risk
- 매 AI-generated code 의 security blind spot.
- 매 prompt injection 의 reproduce.
- 매 hardcoded secret (LLM 의 example).
- 매 outdated security practice.

## 💻 Code

### CI workflow
```yaml
# .github/workflows/devsecops.yml
on: [pull_request, push]

jobs:
  security:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
        with: { fetch-depth: 0 }
      
      # Secret scan
      - uses: trufflesecurity/trufflehog@main
        with:
          path: ./
          base: ${{ github.event.repository.default_branch }}
      
      # SAST
      - uses: snyk/actions/setup@master
      - run: snyk code test --severity-threshold=high
      
      # Dependency
      - run: snyk test --severity-threshold=high
      
      # Container
      - run: docker build -t app .
      - uses: aquasecurity/trivy-action@master
        with:
          image-ref: 'app'
          severity: 'CRITICAL,HIGH'
          exit-code: '1'
      
      # SARIF upload (GitHub Security tab)
      - uses: github/codeql-action/upload-sarif@v3
```

### Custom Semgrep rule (prompt injection)
```yaml
# .semgrep/prompt-injection.yaml
rules:
  - id: llm-prompt-concat
    pattern-either:
      - pattern: |
          $LLM.complete($PROMPT + $USER_INPUT)
      - pattern: |
          $LLM.complete(`...${$USER_INPUT}...`)
    message: |
      Prompt injection: user input concatenated. Use template / sanitize.
    severity: ERROR
    languages: [python, javascript, typescript]
```

### Pre-commit hook (secret + lint)
```yaml
# .pre-commit-config.yaml
repos:
  - repo: https://github.com/Yelp/detect-secrets
    rev: v1.4.0
    hooks:
      - id: detect-secrets
  - repo: https://github.com/pre-commit/pre-commit-hooks
    rev: v4.5.0
    hooks:
      - id: trailing-whitespace
      - id: check-yaml
  - repo: local
    hooks:
      - id: lint
        name: lint
        entry: npm run lint
        language: system
```

### SARIF (security findings format)
```json
{
  "version": "2.1.0",
  "runs": [{
    "tool": { "driver": { "name": "MyScanner" } },
    "results": [{
      "ruleId": "sql-injection",
      "level": "error",
      "message": { "text": "SQL injection in users.ts:42" },
      "locations": [{
        "physicalLocation": {
          "artifactLocation": { "uri": "src/users.ts" },
          "region": { "startLine": 42 }
        }
      }]
    }]
  }]
}
```

### Renovate (dep update + security)
```json
// renovate.json
{
  "extends": ["config:recommended", ":automergePatch"],
  "vulnerabilityAlerts": {
    "labels": ["security"],
    "automerge": true
  }
}
```

## 🤔 결정 기준

| Risk | Tool layer |
|---|---|
| Low (lint, style) | IDE / pre-commit |
| Medium (SAST) | PR gate (Snyk / Sonar) |
| High (CVE, secret) | PR block + alert |
| Critical (zero-day) | Manual + emergency patch |
| AI-generated code | Enhanced review |

**기본값**: IDE + PR + pre-deploy 의 layered. 매 gate 의 different threshold.

## 🤖 LLM 활용
**언제**: 매 production system 의 security strategy. 매 vibe coding 의 review.
**언제 X**: 매 throwaway script. Specific compliance audit (auditor).

## ❌ 안티패턴
- **AI 만 의존**: 매 architecture flaw miss.
- **Manual 만**: 매 mechanical pattern miss.
- **No quality gate**: 매 vulnerability 의 ship.
- **Generic alert (no severity)**: alert fatigue.
- **No secret scan + AI 의 hardcode**: leak.

## 🧪 검증 / 중복
