Security Audit

Perform comprehensive security assessment: $ARGUMENTS

Current Environment

• Dependency scan: !npm audit --audit-level=moderate 2>/dev/null || pip check 2>/dev/null || echo "No package manager detected"
• Environment files: @.env* (if exists)
• Security config: @.github/workflows/security.yml or @security/ (if exists)
• Recent commits: !git log --oneline --grep="security\|fix" -10

Task

Perform systematic security audit following these steps:

1. Environment Setup

   • Identify the technology stack and framework
   • Check for existing security tools and configurations
   • Review deployment and infrastructure setup

2. Dependency Security

   • Scan all dependencies for known vulnerabilities
   • Check for outdated packages with security issues
   • Review dependency sources and integrity
   • Use appropriate tools: npm audit, pip check, cargo audit, etc.

3. Authentication & Authorization

   • Review authentication mechanisms and implementation
   • Check for proper session management
   • Verify authorization controls and access restrictions
   • Examine password policies and storage

4. Input Validation & Sanitization

   • Check all user input validation and sanitization
   • Look for SQL injection vulnerabilities
   • Identify potential XSS (Cross-Site Scripting) issues
   • Review file upload security and validation

5. Data Protection

   • Identify sensitive data handling practices
   • Check encryption implementation for data at rest and in transit
   • Review data masking and anonymization practices
   • Verify secure communication protocols (HTTPS, TLS)

6. Secrets Management

   • Scan for hardcoded secrets, API keys, and passwords
   • Check for proper secrets management practices
   • Review environment variable security
   • Identify exposed configuration files

7. Error Handling & Logging

   • Review error messages for information disclosure
   • Check logging practices for security events
   • Verify sensitive data is not logged
   • Assess error handling robustness

8. Infrastructure Security

   • Review containerization security (Docker, etc.)
   • Check CI/CD pipeline security
   • Examine cloud configuration and permissions
   • Assess network security configurations

9. Security Headers & CORS

   • Check security headers implementation
   • Review CORS configuration
   • Verify CSP (Content Security Policy) settings
   • Examine cookie security attributes

10. Reporting

    • Document all findings with severity levels (Critical, High, Medium, Low)
    • Provide specific remediation steps for each issue
    • Include code examples and file references
    • Create an executive summary with key recommendations

Use automated security scanning tools when available and provide manual review for complex security patterns.
