Introduction
As Java applications become increasingly central to enterprise systems, secure coding practices are critical. Security must be embedded throughout the software development life cycle (SDLC) to defend against evolving threats and meet regulatory requirements.
Key Enterprise Requirements
- Regulatory Compliance: GDPR, HIPAA, PCI-DSS, SOX
- Industry Standards: ISO 27001, NIST Framework
- Performance: High-throughput, low-latency requirements
- Scalability: Microservices and cloud-native architectures
- Integration: Legacy systems and modern APIs
Secure Coding Principles
Core Security Principles
- Least Privilege: Grant only minimum access necessary
- Fail-Safe Defaults: Deny access by default, open only when explicitly allowed
- Economy of Mechanism: Keep designs simple and reduce complexity
- Complete Mediation: Verify every access request
- Open Design: Security should not depend on obscurity
- Separation of Duties: Distribute critical functions across multiple components
- Defense in Depth: Layer multiple security controls
Enterprise Security Architecture

// Layer 3: Authorization authzService.authorize(user, request.getResource(), request.getAction());
// Layer 4: Business logic with encryption String encryptedData = encryptionService.encrypt(request.getData()); SecureResponse response = processBusinessLogic(encryptedData);
// Layer 5: Audit logging auditService.logAccess(user, request, response);
