Audit Expert

Expert guidance for security auditing, compliance assessments, code reviews, vulnerability assessments, and regulatory compliance (SOC 2, GDPR, HIPAA, PCI-DSS).

Core Concepts

Audit Types

• Security Audit: Vulnerability assessment, penetration testing
• Code Audit: Code review, static analysis, security patterns
• Compliance Audit: SOC 2, GDPR, HIPAA, PCI-DSS, ISO 27001
• Infrastructure Audit: Configuration review, access control
• Process Audit: SDLC, change management, incident response

Audit Frameworks

• OWASP ASVS (Application Security Verification Standard)
• NIST Cybersecurity Framework
• CIS Controls
• ISO 27001/27002
• SOC 2 Trust Service Criteria

Audit Process

1. Planning and scoping
2. Information gathering
3. Vulnerability identification
4. Risk assessment
5. Reporting
6. Remediation tracking
7. Follow-up verification

Audit Reporting

Security Audit Report Template

class SecurityAuditReport {
  constructor() {
    this.findings = [];
    this.summary = {
      critical: 0,
      high: 0,
      medium: 0,
      low: 0,
      info: 0,
    };
  }

  addFinding(finding) {
    this.findings.push({
      id: this.findings.length + 1,
      severity: finding.severity,
      title: finding.title,
      description: finding.description,
      location: finding.location,
      recommendation: finding.recommendation,
      references: finding.references || [],
      cvssScore: finding.cvssScore,
      status: 'open',
      discoveredAt: new Date(),
    });

    this.summary[finding.severity]++;
  }

  generateReport() {
    return {
      reportDate: new Date(),
      auditor: 'Security Team',
      scope: this.scope,
      summary: this.summary,
      findings: this.findings.sort(
        (a, b) =>
          this.severityWeight(b.severity) - this.severityWeight(a.severity)
      ),
      recommendations: this.generateRecommendations(),
    };
  }

  severityWeight(severity) {
    const weights = { critical: 5, high: 4, medium: 3, low: 2, info: 1 };
    return weights[severity] || 0;
  }

  generateRecommendations() {
    return [
      'Address all critical and high severity findings immediately',
      'Implement security code review process',
      'Conduct regular penetration testing',
      'Provide security training for developers',
      'Establish vulnerability disclosure program',
    ];
  }
}

// Usage
const audit = new SecurityAuditReport();

audit.addFinding({
  severity: 'critical',
  title: 'SQL Injection in User Search',
  description: 'User search endpoint concatenates user input into SQL query',
  location: 'src/controllers/users.js:45',
  recommendation: 'Use parameterized queries or ORM with proper escaping',
  references: ['CWE-89', 'OWASP A03:2021'],
  cvssScore: 9.8,
});

const report = audit.generateReport();
