# CI/CD Integration Guide

Integrate llm-security into your CI/CD pipeline for automated security scanning of AI/LLM projects. The standalone CLI runs 10 deterministic Node.js scanners — no AI models, no external API calls, no data leaves your pipeline environment.

## Data Sovereignty

**The standalone CLI makes zero network calls by default.** All 10 scanners operate locally on your source code using Shannon entropy analysis, regex pattern matching, AST traversal, and git log parsing. No data is transmitted to any external service.

**Exception: supply-chain-recheck** — When scanning lockfiles for known vulnerabilities, this scanner optionally queries the [OSV.dev](https://osv.dev/) batch API. This sends only package names and versions (not source code) over HTTPS. To disable: set `LLM_SECURITY_SCR_OFFLINE=1`.

**What about Claude Code integration?** The Claude Code plugin (hooks, agents, commands) uses AI models and sends data to Anthropic. These components are **not included** in the standalone CLI. When you run `npx llm-security scan`, only deterministic scanners execute.

### Schrems II / NSM Compliance

- Standalone CLI: **fully compliant** — no cross-border data transfer
- OSV.dev queries (opt-in): sends package metadata to Google-operated API — evaluate per your organization's data classification
- Claude Code plugin: sends code context to Anthropic (US) — requires data processing agreement for regulated environments

### Norwegian Regulatory Context

- **NSM Grunnprinsipper:** Automated security scanning fulfills GP 3.1 (vulnerability management) and GP 2.4 (secure development)
- **Digitaliseringsdirektoratet:** Aligns with recommended practices for AI system development lifecycle security
- **EU AI Act (expected Aug 2026):** Directly supports Art. 9 (risk management) and Art. 15 (cybersecurity) requirements

## 5-Minute Setup

### GitHub Actions

Copy `ci/github-action.yml` to `.github/workflows/llm-security.yml`:

```yaml
name: LLM Security Scan
on: [push, pull_request]
jobs:
  security-scan:
    runs-on: ubuntu-latest
    permissions:
      security-events: write
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: '18'
      - run: npx llm-security scan . --fail-on high --format sarif --output-file results.sarif
      - uses: github/codeql-action/upload-sarif@v3
        if: always()
        with:
          sarif_file: results.sarif
```

SARIF results appear in the repository's **Security** tab under **Code scanning alerts**.

### Azure DevOps

Copy `ci/azure-pipelines.yml` to your pipeline, or include the scan step in an existing pipeline:

```yaml
steps:
  - task: NodeTool@0
    inputs:
      versionSpec: '18.x'
  - script: npx llm-security scan . --fail-on high --format sarif --output-file $(Build.ArtifactStagingDirectory)/results.sarif
    displayName: Run llm-security scan
  - task: PublishBuildArtifacts@1
    condition: always()
    inputs:
      pathToPublish: $(Build.ArtifactStagingDirectory)/results.sarif
      artifactName: llm-security-scan
```

For Azure DevOps Advanced Security, replace `PublishBuildArtifacts@1` with `AdvancedSecurity-Publish@1`.

### GitLab CI

Add to `.gitlab-ci.yml`:

```yaml
llm-security-scan:
  image: node:18-alpine
  stage: test
  script:
    - npx llm-security scan . --fail-on high --format sarif --output-file results.sarif
  artifacts:
    paths:
      - results.sarif
    reports:
      sast: results.sarif
    when: always
```

SAST report parsing requires GitLab Ultimate. On Free/Premium tiers, download the SARIF artifact manually.

## Configuration

### CLI Flags

| Flag | Description |
|------|-------------|
| `--fail-on <severity>` | Exit 1 if any finding at or above severity exists. Values: `critical`, `high`, `medium`, `low` |
| `--compact` | One-liner per finding format. Reduces CI log noise |
| `--format sarif` | Output OASIS SARIF 2.1.0 (default: JSON) |
| `--output-file <path>` | Write full results to file. Stdout gets compact aggregate |
| `--baseline` | Diff against stored baseline (show new/resolved findings) |
| `--save-baseline` | Save current results as baseline for future diffs |

### Policy File

Configure defaults in `.llm-security/policy.json`:

```json
{
  "ci": {
    "failOn": "high",
    "compact": true
  }
}
```

CLI flags always take precedence over policy file values.

### Environment Variables

| Variable | Description |
|----------|-------------|
| `LLM_SECURITY_SCR_OFFLINE=1` | Disable OSV.dev network calls in supply-chain-recheck |
| `LLM_SECURITY_AUDIT_LOG=<path>` | Write structured JSONL audit trail (SIEM-ready) |

## Exit Codes

| Code | Meaning | When |
|------|---------|------|
| `0` | Clean / below threshold | No findings at or above `--fail-on` level, or ALLOW verdict |
| `1` | Threshold exceeded | Findings at or above `--fail-on` level, or WARNING verdict (without `--fail-on`) |
| `2` | Block | BLOCK verdict (only without `--fail-on`) |

With `--fail-on`, exit codes are binary: 0 (clean) or 1 (threshold exceeded). Without `--fail-on`, the legacy tri-state (0/1/2) is preserved.

## What Gets Scanned

The 10 deterministic scanners cover:

| Scanner | Detects |
|---------|---------|
| Unicode | Zero-width characters, homoglyphs, Unicode Tag steganography |
| Entropy | High-entropy strings (potential secrets/tokens) |
| Permission | Overly broad permissions, missing tool justification |
| Dependency | Known vulnerable packages, typosquats |
| Taint | Untrusted input flows to sensitive operations |
| Git forensics | Force pushes, sensitive file history, author anomalies |
| Network | Suspicious URLs, exfiltration endpoints, C2 patterns |
| Memory poisoning | Injection patterns in CLAUDE.md, memory files, rules |
| Supply chain | Lockfile audit, blocklists, OSV.dev (opt-in) |
| Toxic flow | Lethal trifecta correlation (input + access + exfil) |

## Local Testing

Test the exact same command locally before adding to CI:

```bash
# With npx (requires npm publish)
npx llm-security scan . --fail-on high --compact

# With local clone
node bin/llm-security.mjs scan . --fail-on high --compact
```
