Applications are the primary interface between the business and its customers, making them a top target for cyber attacks. This course provides a comprehensive guide to building security into the entire Software Development Lifecycle (SDLC), from initial design to deployment and maintenance. Participants will move beyond simple vulnerability scanning to master threat modeling, secure coding practices, and continuous security testing. The program emphasizes shifting security "left" by integrating automated tools and processes, ensuring developers are empowered to write secure code and mitigating costly, late-stage security flaws.

- Application Security Specialists and Analysts.
- DevOps and DevSecOps Engineers.
- Solution and Enterprise Architects.
- Quality Assurance (QA) and Testing Teams.
- Product Owners and Managers.
- CISO and Security Managers overseeing development teams.
Methodology
- Hands-on coding labs focused on fixing and exploiting OWASP Top 10 vulnerabilities.
- Group threat modeling exercises for a new application feature.
- Case studies on successful DevSecOps pipeline implementations.
- Practical exercises using simplified SAST/SCA tools to analyze code.
- Discussions on designing a developer security training program.
Personal Impact
- Ability to integrate security seamlessly into existing development workflows.
- Deep understanding of threat modeling and secure design principles.
- Expertise in utilizing automated AppSec tools (SAST, DAST, SCA).
- Enhanced career path into specialized AppSec or DevSecOps roles.
- Skills to write demonstrably more secure, resilient code.
- Credibility in collaborating with security and compliance teams.
Organizational Impact
- Significant reduction in application-layer vulnerabilities and subsequent breaches.
- Lower cost of remediation by finding and fixing bugs earlier in the SDLC.
- Faster time-to-market due to fewer security roadblocks late in development.
- Improved developer productivity and autonomy through integrated tools.
- Demonstrable due diligence for compliance requiring application security.
- Stronger resilience against zero-day and supply chain attacks.
Course Outline
Unit 1: Fundamentals of Application Security
Section 1.1: The Application Attack Landscape- Understanding the OWASP Top 10 and its relevance.
- Common application vulnerabilities (e.g., injection, broken access control).
- The cost and impact of application security breaches.
- The philosophy of "Shifting Left" in the SDLC.
- Principles of secure design (least privilege, secure defaults).
- The process of effective threat modeling (e.g., STRIDE, DREAD).
- Identifying trust boundaries and data flow in application architecture.
- Defining security requirements and acceptance criteria early in the design phase.
Unit 2: Integrating Security into the Development Process
Section 2.1: Secure Coding Practices- Best practices for preventing common web application vulnerabilities.
- Handling user input securely (validation, sanitization, encoding).
- Securely managing state and session information.
- Cryptographic best practices and key management within applications.
- Creating and socializing secure coding standards and guidelines.
- Embedding security requirements into Agile user stories and sprints.
- Effective security awareness and training for developers.
- The role of the Security Champion program.
Unit 3: Automated Security Testing
Section 3.1: Static and Dynamic Analysis- Static Application Security Testing (SAST) and code analysis tools.
- Dynamic Application Security Testing (DAST) for runtime flaws.
- Interactive Application Security Testing (IAST) and its benefits.
- Selecting and tuning automated testing tools for accuracy.
- Software Composition Analysis (SCA) for third-party libraries.
- Managing known vulnerabilities in open-source components.
- Creating a Software Bill of Materials (SBOM) for transparency.
- Securing the CI/CD pipeline and code repository (DevSecOps).
Unit 4: Post-Deployment and Operational Security
Section 4.1: Runtime Protection- Implementing Web Application Firewalls (WAFs) and API Gateways.
- Runtime Application Self-Protection (RASP) and its deployment models.
- Secure configuration of application servers and containers.
- API security: authentication, authorization, and rate limiting.
- Establishing a bug bounty or coordinated vulnerability disclosure program.
- Prioritizing and tracking remediation of application vulnerabilities.
- Developing application-specific incident response playbooks.
- Secure logging, monitoring, and alerting for application-layer attacks.
Unit 5: Advanced Topics and DevSecOps Integration
Section 5.1: DevSecOps Pipelines- Integrating SAST/DAST/SCA into Continuous Integration (CI) tools.
- Automating security gates and "breaking the build" on severe findings.
- Using Infrastructure as Code (IaC) security scanning tools.
- Orchestrating security tools for end-to-end automation.
- Security for serverless and function-as-a-service architectures.
- Advanced container security and admission controllers (Kubernetes).
- The use of AI/ML in application security testing.
- Security for mobile applications (storage, communication, and APIs).
