Q: What is Application Security Testing and why is this important for modern development?
Application security testing is a way to identify vulnerabilities in software before they are exploited. It's important to test for vulnerabilities in today's rapid-development environments because even a small vulnerability can allow sensitive data to be exposed or compromise a system. Modern AppSec testing includes static analysis (SAST), dynamic analysis (DAST), and interactive testing (IAST) to provide comprehensive coverage across the software development lifecycle.
Q: What is the difference between a vulnerability that can be exploited and one that can only be "theorized"?
A: An exploitable vulnerability has a clear path to compromise that attackers can realistically leverage, while theoretical vulnerabilities may have security implications but lack practical attack vectors. Understanding this distinction helps teams prioritize remediation efforts and allocate resources effectively.
How should organizations test for security in microservices?
A: Microservices require a comprehensive security testing approach that addresses both individual service vulnerabilities and potential issues in service-to-service communications. This includes API security testing, network segmentation validation, and authentication/authorization testing between services.
Q: What is the difference between SAST tools and DAST?
DAST simulates attacks to test running applications, while SAST analyses source code but without execution. SAST can find issues earlier but may produce false positives, while DAST finds real exploitable vulnerabilities but only after code is deployable. A comprehensive security program typically uses both approaches.
Q: How do organizations implement effective security champions programs in their organization?
Programs that promote security champions designate developers to be advocates for security, and bridge the gap between development and security. Effective programs provide champions with specialized training, direct access to security experts, and time allocated for security activities.

A: Machine learning security testing must address data poisoning, model manipulation, and output validation. Organizations should implement controls to protect both training data and model endpoints, while monitoring for unusual behavior patterns.
Q: What is the role of security in code reviews?
A: Where possible, security-focused code reviews should be automated. Human reviews should focus on complex security issues and business logic. Reviews should use standardized checklists and leverage automated tools for consistency.
Q: What is the best way to test security for event-driven architectures in organizations?
A: Event-driven architectures require specific security testing approaches that validate event processing chains, message integrity, and access controls between publishers and subscribers. Testing should ensure that events are validated, malformed messages are handled correctly, and there is protection against event injection.
Q: How do organizations implement Infrastructure as Code security testing effectively?
Infrastructure as Code (IaC), security testing should include a review of configuration settings, network security groups and compliance with security policy. Automated tools must scan IaC template before deployment, and validate the running infrastructure continuously.
Q: What role do Software Bills of Materials (SBOMs) play in application security?
A: SBOMs provide a comprehensive inventory of software components, dependencies, and their security status. This visibility allows organizations to identify and respond quickly to newly discovered vulnerabilities. It also helps them maintain compliance requirements and make informed decisions regarding component usage.
Q: What is the best way to test WebAssembly security?
WebAssembly testing for security must include memory safety, input validity, and possible sandbox escape vulnerability. The testing should check the implementation of security controls both in WebAssembly and its JavaScript interfaces.
Q: What are the best practices for implementing security controls in service meshes?
A: The security controls for service meshes should be focused on authentication between services, encryption, policies of access, and observability. Zero-trust principles should be implemented by organizations and centralized policy management maintained across the mesh.
