Security Analyzer - Comprehensive Security Auditing Skill

Overview

This skill provides multi-vector security analysis combining static code analysis, dynamic testing, dependency auditing, secrets detection, and OWASP Top 10 compliance checking. Uses coordinated agents with validation gates between phases.

Phase 1: Static Code Analysis

Objective

Identify code-level vulnerabilities, security anti-patterns, and unsafe practices.

Security Manager Setup

# Initialize security audit session
npx claude-flow@alpha hooks pre-task --description "Security static analysis initialization"
npx claude-flow@alpha hooks session-restore --session-id "security-audit-${DATE}"

# Set up memory namespace
npx claude-flow@alpha memory store \
  --key "swarm/security/config" \
  --value '{
    "scan_type": "static",
    "severity_threshold": "medium",
    "frameworks": ["owasp", "cwe"],
    "timestamp": "'$(date -Iseconds)'"
  }'

Code Analyzer Execution

# Spawn code analyzer agent for static analysis
# Agent performs:

# 1. SQL Injection Detection
npx claude-flow@alpha hooks pre-task --description "SQL injection vulnerability scan"

# Scan patterns:
# ❌ VULNERABLE:
#   const query = "SELECT * FROM users WHERE id = " + userId;
#   db.query("SELECT * FROM " + tableName);
#
# ✅ SECURE:
#   const query = "SELECT * FROM users WHERE id = ?";
#   db.query(query, [userId]);

grep -rn "\.query\|\.exec" --include="*.js" --include="*.ts" . | \
  grep -v "?" | grep -v "\$[0-9]" > /tmp/sql-findings.txt

# 2. XSS Vulnerability Detection
# ❌ VULNERABLE:
#   element.innerHTML = userInput;
#   eval(userInput);
#   new Function(userInput)();
#
# ✅ SECURE:
#   element.textContent = userInput;
#   JSON.parse(sanitizedInput);

grep -rn "innerHTML\|eval\|new Function" --include="*.js" --include="*.jsx" . > /tmp/xss-findings.txt

# 3. Path Traversal Detection
# ❌ VULNERABLE:
#   fs.readFile(userPath);
#   require(userInput);
#
# ✅ SECURE:
#   const safePath = path.join(baseDir, path.normalize(userPath));
#   if (!safePath.startsWith(baseDir)) throw new Error('Invalid path');

grep -rn "readFile\|writeFile\|require.*\+" --include="*.js" . > /tmp/path-traversal-findings.txt

# 4. Insecure Cryptography
# ❌ VULNERABLE:
#   crypto.createHash('md5');
#   crypto.createCipher('des', key);
#
# ✅ SECURE:
#   crypto.createHash('sha256');
#   crypto.createCipheriv('aes-256-gcm', key, iv);

grep -rn "md5\|sha1\|des\|rc4" --include="*.js" --include="*.ts" . > /tmp/crypto-findings.txt

# Store findings in memory
npx claude-flow@alpha memory store \
  --key "swarm/security/static-analysis" \
  --value "$(cat /tmp/*-findings.txt | jq -Rs '{findings: ., timestamp: now}')"

npx claude-flow@alpha hooks post-task --task-id "static-analysis"

Validation Gate 1

# Check if critical vulnerabilities found
CRITICAL_COUNT=$(cat /tmp/*-findings.txt | grep -c ".")

if [ "$CRITICAL_COUNT" -gt 0 ]; then
  echo "⚠️  GATE FAILED: $CRITICAL_COUNT potential vulnerabilities found"
  npx claude-flow@alpha hooks notify --message "Static analysis found $CRITICAL_COUNT issues - review required"
  # Continue but flag for review
fi

Phase 2: Dynamic Security Testing

Objective

Runtime vulnerability detection through active testing and fuzzing.

Tester Agent Execution

npx claude-flow@alpha hooks pre-task --description "Dynamic security testing"

# 1. Authentication Bypass Testing
cat > /tmp/auth-test.js << 'EOF'
// Test suite for authentication vulnerabilities
const axios = require('axios');

    // SQL Injection in auth
    { username: "admin'--", password: "anything" },
    { username: "admin' OR '1'='1", password: "" },

    // JWT manipulation
    { token: "eyJ0eXAiOiJKV1QiLCJhbGciOiJub25lIn0..." }, // None algorithm

    // Session fixation
    { session: "../../admin-session" },

    // NoSQL injection
    { username: { "$ne": null }, password: { "$ne": null } }
  ];

  const vulnerabilities = [];

  for (const test of tests) {
    try {
      const response = await axios.post('http://localhost:3000/login', test);
      if (response.status === 200) {
        vulnerabilities.push({
          type: 'AUTH_BYPASS',
          severity: 'CRITICAL',
          payload: test,
          description: 'Authentication bypass successful'
        });
      }
    } catch (e) {
      // Expected - auth failed
    }
  }

  return vulnerabilities;
}

module.exports = { testAuthBypass };

# 2. CSRF Testing
cat > /tmp/csrf-test.js << 'EOF'
async function testCSRF() {
  const response = await axios.post('http://localhost:3000/api/transfer', {
    to: 'attacker',
    amount: 1000
  }, {
    headers: {
      'Origin': 'http://evil.com',
      'Referer': 'http://evil.com'
    }
  });

  // Should be rejected without CSRF token
  if (response.status === 200) {
    return {
      type: 'CSRF',
      severity: 'HIGH',
      description: 'Missing CSRF protection on state-changing operation'
    };
  }

EOF

# 3. Rate Limiting Test
cat > /tmp/rate-limit-test.js << 'EOF'
async function testRateLimit() {
  const requests = [];
  for (let i = 0; i < 1000; i++) {
    requests.push(axios.get('http://localhost:3000/api/data'));
  }

  const responses = await Promise.all(requests);
  const successCount = responses.filter(r => r.status === 200).length;

  if (successCount > 100) {
    return {
      type: 'NO_RATE_LIMIT',
      severity: 'MEDIUM',
      description: `No rate limiting detected - ${successCount}/1000 requests succeeded`
    };
  }

## Recommendations

1. **Critical Priority:**
   - Fix all critical runtime vulnerabilities immediately
   - Remove exposed secrets from codebase
   - Update dependencies with critical CVEs

2. **High Priority:**
   - Address SQL injection vulnerabilities
   - Implement missing authentication checks
   - Configure security headers

3. **Medium Priority:**
   - Improve OWASP compliance score
   - Add rate limiting
   - Enhance logging and monitoring

  ├─ static-analysis     # Phase 1 findings
  ├─ dynamic-testing     # Phase 2 findings

Real-World Examples

Example 1: SQL Injection Found

// ❌ VULNERABLE CODE DETECTED:
app.get('/user', (req, res) => {
  const query = `SELECT * FROM users WHERE id = ${req.query.id}`;
  db.query(query, (err, results) => {
    res.json(results);
  });
});

// ✅ RECOMMENDED FIX:
app.get('/user', (req, res) => {
  const query = 'SELECT * FROM users WHERE id = ?';
  db.query(query, [req.query.id], (err, results) => {
    if (err) return res.status(500).json({ error: 'Database error' });
    res.json(results);
  });
});

Example 2: Exposed API Key

// ❌ VULNERABLE CODE DETECTED:
const apiKey = 'EXAMPLE_REDACTED_NOT_REAL_KEY';
axios.get('https://api.stripe.com/v1/charges', {
  headers: { 'Authorization': `Bearer ${apiKey}` }
});

// ✅ RECOMMENDED FIX:
const apiKey = process.env.STRIPE_SECRET_KEY;
if (!apiKey) throw new Error('STRIPE_SECRET_KEY not configured');
axios.get('https://api.stripe.com/v1/charges', {
  headers: { 'Authorization': `Bearer ${apiKey}` }
});

Example 3: Missing Authorization

// ❌ VULNERABLE CODE DETECTED:
app.delete('/api/users/:id', (req, res) => {
  User.findByIdAndDelete(req.params.id)
    .then(() => res.json({ success: true }))
    .catch(err => res.status(500).json({ error: err.message }));
});

// ✅ RECOMMENDED FIX:
app.delete('/api/users/:id', authenticate, authorize('admin'), (req, res) => {
  // Verify user can only delete their own account or is admin
  if (req.user.id !== req.params.id && req.user.role !== 'admin') {
    return res.status(403).json({ error: 'Forbidden' });
  }

  User.findByIdAndDelete(req.params.id)
    .then(() => res.json({ success: true }))
    .catch(err => res.status(500).json({ error: err.message }));
});
