Security Hardening

Harden application security configuration

Instructions

1. Security Assessment and Baseline

   • Conduct comprehensive security audit of current application
   • Identify potential vulnerabilities and attack vectors
   • Analyze authentication and authorization mechanisms
   • Review data handling and storage practices
   • Assess network security and communication protocols

2. Authentication and Authorization Hardening

   • Implement strong password policies and multi-factor authentication
   • Configure secure session management with proper timeouts
   • Set up role-based access control (RBAC) with least privilege principle
   • Implement JWT security best practices or secure session tokens
   • Configure account lockout and brute force protection

3. Input Validation and Sanitization

   • Implement comprehensive input validation for all user inputs
   • Set up SQL injection prevention with parameterized queries
   • Configure XSS protection with proper output encoding
   • Implement CSRF protection with tokens and SameSite cookies
   • Set up file upload security with type validation and sandboxing

4. Secure Communication

   • Configure HTTPS with strong TLS/SSL certificates
   • Implement HTTP Strict Transport Security (HSTS)
   • Set up secure API communication with proper authentication
   • Configure certificate pinning for mobile applications
   • Implement end-to-end encryption for sensitive data transmission

5. Data Protection and Encryption

   • Implement encryption at rest for sensitive data
   • Configure secure key management and rotation
   • Set up database encryption and access controls
   • Implement proper secrets management (avoid hardcoded secrets)
   • Configure secure backup and recovery procedures

6. Security Headers and Policies

   • Configure Content Security Policy (CSP) headers
   • Set up X-Frame-Options and X-Content-Type-Options headers
   • Implement Referrer Policy and Feature Policy headers
   • Configure CORS policies with proper origin validation
   • Set up security.txt file for responsible disclosure

7. Dependency and Supply Chain Security

   • Audit and update all dependencies to latest secure versions
   • Implement dependency vulnerability scanning
   • Configure automated security updates for critical dependencies
   • Set up software composition analysis (SCA) tools
   • Implement dependency pinning and integrity checks

8. Infrastructure Security

   • Configure firewall rules and network segmentation
   • Implement intrusion detection and prevention systems
   • Set up secure logging and monitoring
   • Configure secure container images and runtime security
   • Implement infrastructure as code security scanning

9. Application Security Controls

   • Implement rate limiting and DDoS protection
   • Set up web application firewall (WAF) rules
   • Configure secure error handling without information disclosure
   • Implement proper logging for security events
   • Set up security monitoring and alerting

10. Security Testing and Validation

    • Conduct penetration testing and vulnerability assessments
    • Implement automated security testing in CI/CD pipeline
    • Set up static application security testing (SAST)
    • Configure dynamic application security testing (DAST)
    • Create security incident response plan and procedures
    • Document security controls and compliance requirements
