What This Course Covers

Core Application Security & OWASP

• Understanding the OWASP Top 10 framework and its application to Java environments
• Implementing strategies to prevent SQL Injection through parameterized queries in JPA
• Defending against Cross-Site Scripting (XSS) to prevent malicious script execution
• Mitigating Cross-Site Request Forgery (CSRF) to protect state-changing requests
• Validating and sanitizing user input to prevent injection-based attacks

Authentication and Authorization

• Configuring Spring Security for comprehensive access control and application protection
• Implementing JSON Web Tokens (JWT) for stateless authentication in REST APIs
• Integrating OAuth2 for secure, delegated authorization and third-party logins
• Designing role-based and permission-based access control (RBAC) for fine-grained security
• Managing sessions and cookies securely to prevent session hijacking and fixation

Data Protection and Secret Management

• Applying strong encryption standards using AES for data at rest and in transit
• Implementing secure password hashing with bcrypt to protect user credentials
• Establishing secure methods for storing secrets and sensitive configuration data
• Configuring proper Cross-Origin Resource Sharing (CORS) policies to control API access
• Handling secure file uploads to prevent remote code execution and directory traversal

Application Resilience and Architecture

• Integrating Resilience4j with Spring Boot to handle circuit breaking and rate limiting
• Writing resilient code that gracefully handles failures and prevents cascading crashes
• Implementing load balancing strategies to distribute traffic and increase reliability
• Applying microservices patterns to ensure secure communication between distributed services
• Designing system recovery strategies to maintain uptime during security incidents

Secure Development Lifecycle (SDLC)

• Applying Secure SDLC principles to shift security left in the development process
• Using automated tools to detect vulnerabilities in code and third-party dependencies
• Establishing secure coding standards and guidelines for enterprise Java teams
• Implementing security testing practices to identify flaws before production deployment
• Developing a mindset for "defense in depth" across the entire application stack
