- **IF** implementing authentication → Apply `isms-compliance`: Follow [Access Control Policy](https://github.com/Hack23/ISMS-PUBLIC/blob/main/Access_Control_Policy.md)
- **IF** storing data → Apply `isms-compliance`: Follow [Data Classification Policy](https://github.com/Hack23/ISMS-PUBLIC/blob/main/Data_Classification_Policy.md)
- **IF** changing CI/CD → Apply `security-by-design`: Ensure SLSA Level 3 compliance and provenance
- **IF** documenting security → Apply `documentation-standards`: Include ISMS policy references, control descriptions, audit evidence
- **IF** testing security features → Apply `testing-strategy`: Test auth, authorization, input validation with ≥95% coverage

## 📏 Enforcement Rules

**ALWAYS follow these mandatory rules:**

### Rule 1: OSSF Scorecard ≥8.0
**MUST** maintain OSSF Scorecard rating ≥8.0/10. **NEVER** merge code that drops score below 8.0.

### Rule 2: SLSA Level 3
**MUST** maintain SLSA Level 3 build provenance. **NEVER** disable provenance generation or attestation.

### Rule 3: SBOM Quality ≥7.0
**MUST** maintain SBOM quality score ≥7.0/10 (CycloneDX NTIA/BSI validation). **NEVER** ship without valid SBOM.

### Rule 4: No Secrets in Code
**NEVER** commit secrets, API keys, credentials, or tokens. **ALWAYS** use GitHub Secrets and environment variables.

### Rule 5: Approved Licenses Only
**MUST** use approved open-source licenses: MIT, Apache-2.0, BSD variants, ISC, CC0-1.0, Unlicense. **NEVER** add GPL, AGPL, or proprietary licenses.

### Rule 6: SHA-Pinned Actions
**ALWAYS** pin GitHub Actions to full commit SHA (e.g., `uses: actions/checkout@de0fac2e4500dabe0009e67214ff5f5447ce83dd`). **NEVER** use tags or branches.

### Rule 7: Input Sanitization
**ALWAYS** sanitize and validate ALL user inputs. **NEVER** trust client-side validation alone.

### Rule 8: Dependency Verification
**MUST** run `npm audit` before adding dependencies. **NEVER** add dependencies with known vulnerabilities.

### Rule 9: CodeQL Scanning
**MUST** pass CodeQL security scanning with zero high/critical alerts. **NEVER** merge code with unresolved security findings.

### Rule 10: ISMS Alignment
**MUST** align all security practices with [Hack23 ISMS policies](https://github.com/Hack23/ISMS-PUBLIC). **NEVER** bypass security policies.

## Supply Chain Security (OSSF Scorecard & SLSA)

**MUST maintain high supply chain security ratings:**

### OSSF Scorecard Requirements (Target: ≥8.0/10)

| Check | Target | Enforcement |
|-------|--------|-------------|

# Target: ≥8.0/10
# Current checks: View at https://scorecard.dev/
```

### SLSA Level 3 Requirements

**MUST maintain SLSA Level 3 compliance:**

| Requirement | Implementation | Verification |
|-------------|----------------|--------------|
| **Build Service** | GitHub Actions | ✅ Hosted build platform |
| **Provenance** | SLSA Generator | ✅ Signed build attestations |
| **Isolated Build** | Ephemeral runners | ✅ Clean environment per build |
| **Parameterless** | No workflow inputs | ✅ Reproducible builds |
| **Hermetic** | Dependency pinning | ✅ Immutable dependencies |
| **Non-falsifiable** | Keyless signing | ✅ Sigstore attestation |

**Generate Provenance:**
```yaml
# In .github/workflows/release.yml
- uses: slsa-framework/slsa-github-generator@v1.9.0
  with:
    provenance-name: provenance.intoto.jsonl
```

### SBOM Quality (Target: ≥7.0/10)

**MUST maintain high SBOM quality per NTIA and BSI standards:**

```bash
# Generate SBOM
npm run sbom:generate

# Validate SBOM quality
npx @cyclonedx/cdxgen --validate

# Check SBOM score (target: ≥7.0/10)
# Includes:
# - Complete component inventory
# - License information
# - Dependency relationships
# - Vulnerability data
# - Author/supplier information
```

**SBOM Requirements:**
- ✅ CycloneDX or SPDX format
- ✅ All dependencies listed (direct + transitive)
- ✅ License declared for each component
- ✅ Vulnerability data included (VEX)
- ✅ SBOM signed and attested
- ✅ Updated on every release

## Secure Coding Practices (OWASP Top 10)

**ALWAYS follow OWASP secure coding guidelines:**

### Input Validation and Sanitization
```typescript
// WRONG: No validation or sanitization
function processApiInput(data: string) {
  return eval(data); // Code injection vulnerability!
}

// CORRECT: Validate and sanitize input
function processApiInput(data: unknown): string {
  if (typeof data !== 'string') {
    throw new Error("Invalid input type");
  }
  
  // Validate format
  if (data.length > 1000) {
    throw new Error("Input too long");
  }
  
  // Sanitize by removing dangerous characters
  return data.replace(/[<>\"']/g, '');
}

// CORRECT: Validate structured data
import { z } from 'zod';

const MemberSchema = z.object({
  id: z.string().uuid(),
  name: z.string().min(1).max(100),
  email: z.string().email(),
});

function validateMember(data: unknown) {
  return MemberSchema.parse(data);
}
```

### Authentication and Authorization
```typescript
// CORRECT: Follow Access Control Policy requirements
import { verifyToken, checkPermission } from "./auth";

async function secureEndpoint(req: Request): Promise<Response> {
  // 1. Authenticate: Verify identity
  const user = await verifyToken(req.headers.get("Authorization"));
  if (!user) {
    return new Response("Unauthorized", { status: 401 });
  }
  
  // 2. Authorize: Check permissions
  if (!checkPermission(user, "resource:read")) {
    return new Response("Forbidden", { status: 403 });
  }
  
  // 3. Process request
  return new Response("Success", { status: 200 });
}
```

### Sensitive Data Protection
```typescript
// WRONG: Logging sensitive data
console.log("User login:", { email, password }); // NEVER log passwords!

// CORRECT: Mask sensitive data in logs
function logSecurely(data: { email: string; password: string }) {
  console.log("User login:", { 
    email: data.email,
    password: "***REDACTED***" 
  });
}

// CORRECT: Hash sensitive data before storage
import { createHash } from 'crypto';

function hashApiKey(apiKey: string): string {
  return createHash('sha256').update(apiKey).digest('hex');
}
```

### Error Handling (Fail Securely)
```typescript
// WRONG: Leaking implementation details
catch (error) {
  return new Response(JSON.stringify({ error: error.stack }), { 
    status: 500 
  }); // Leaks stack trace!
}

// CORRECT: Generic error messages, detailed logs
catch (error) {
  console.error("Internal error:", error); // Log details server-side
  return new Response(JSON.stringify({ 
    error: "Internal server error" 
  }), { 
    status: 500 
  }); // Generic message to client
}
```

### API Security
```typescript
// CORRECT: Rate limiting for API endpoints
import { RateLimiter } from 'limiter';

const limiter = new RateLimiter({
  tokensPerInterval: 100,
  interval: 'minute'
});

async function handleApiRequest(req: Request): Promise<Response> {
  if (!await limiter.removeTokens(1)) {
    return new Response("Too many requests", { status: 429 });
  }
  
  // Process request
}

// CORRECT: Validate API parameters
function validateQueryParams(params: URLSearchParams): {
  page: number;
  limit: number;
} {
  const page = Math.max(1, parseInt(params.get('page') || '1'));
  const limit = Math.min(100, Math.max(1, parseInt(params.get('limit') || '10')));
  
  return { page, limit };
}
```

## Static Analysis

- Ensure code passes CodeQL scanning
- Address security alerts proactively
- Review dependency vulnerabilities in PRs
- Maintain high OSSF Scorecard ratings
- Monitor security advisories

## License Compliance Automation

**ALWAYS verify licenses before adding dependencies:**

### Approved Open-Source Licenses
✅ **Permissive Licenses (ALLOWED):**
- MIT License
- Apache License 2.0
- BSD 2-Clause "Simplified" License
- BSD 3-Clause "New" or "Revised" License
- ISC License
- CC0 1.0 Universal (Public Domain)
- The Unlicense (Public Domain)

❌ **Restrictive Licenses (NOT ALLOWED):**
- GPL (all versions)
- AGPL (all versions)
- LGPL (all versions)
- MPL (Mozilla Public License)
- CDDL (Common Development and Distribution License)
- EPL (Eclipse Public License)
- Any proprietary or commercial licenses

### License Verification Workflow
```bash
# BEFORE adding ANY dependency
# Step 1: Check for vulnerabilities
npm audit

# Step 2: Review license manually
npm info <package-name> license

# Step 3: If approved, add dependency
npm install <package-name>

# Step 4: Update SBOM
npm run sbom:generate
```

**NEVER add a dependency with unapproved license** - per [Open Source Policy](https://github.com/Hack23/ISMS-PUBLIC/blob/main/Open_Source_Policy.md)

## Static Analysis and Security Testing

**MUST pass all security scans:**

### CodeQL Configuration
```yaml
# .github/workflows/codeql.yml
- uses: github/codeql-action/analyze@v2
  with:
    category: "/language:typescript"
    queries: security-extended
```

**CodeQL Requirements:**
- ✅ **Zero high/critical alerts** before merge
- ✅ Scans on every PR and push to main
- ✅ Extended security query pack enabled
- ✅ SARIF results uploaded to GitHub Security

### Dependency Scanning (npm audit)
```bash
# Check for known vulnerabilities
npm audit

# Fix automatically when possible
npm audit fix

# For breaking changes, review manually
npm audit fix --force

# Target: Zero vulnerabilities (high/critical/moderate)
```

## 🎯 Decision Frameworks

### Framework 1: Dependency Addition
- **IF** adding dependency → **MUST** run `npm audit`
- **IF** vulnerability found → **MUST** find alternative or wait for patch
- **IF** license is GPL/AGPL/LGPL → **NEVER** add, find MIT/Apache alternative
- **IF** approved → Add dependency, regenerate SBOM, verify OSSF score

### Framework 2: Input Handling
- **IF** processing user input → **MUST** validate format, length, and type
- **IF** building SQL/NoSQL queries → **MUST** use parameterized queries
- **IF** executing commands → **NEVER** use user input, or sanitize strictly
- **IF** parsing JSON → **MUST** use schema validation (zod, joi, etc.)

### Framework 3: Authentication
- **IF** implementing authentication → Follow [Access Control Policy](https://github.com/Hack23/ISMS-PUBLIC/blob/main/Access_Control_Policy.md)
- **IF** storing credentials → **MUST** use secure hashing (bcrypt, argon2)
- **IF** using tokens → **MUST** use short expiry (≤15min access, ≤7d refresh)
- **IF** failed authentication → Implement rate limiting

### Framework 4: Data Protection
- **IF** storing user data → Classify per [Data Classification Policy](https://github.com/Hack23/ISMS-PUBLIC/blob/main/Data_Classification_Policy.md)
- **IF** personal data → Follow [Privacy Policy](https://github.com/Hack23/ISMS-PUBLIC/blob/main/Privacy_Policy.md) and GDPR
- **IF** sensitive data → Encrypt at rest and in transit (TLS 1.3)
- **IF** logging data → **NEVER** log passwords, tokens, or PII

### Framework 5: CI/CD Security
- **IF** adding GitHub Action → **MUST** pin to full SHA, not tag
- **IF** modifying workflow → Maintain SLSA Level 3 and provenance
- **IF** adding secrets → Use GitHub Secrets with least-privilege access
- **IF** third-party action → Verify source, check OSSF score, review code
