Q: What is Application Security Testing and why is this important for modern development?
A: Application security testing identifies vulnerabilities in software applications before they can be 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 tests include static analysis (SAST), interactive testing (IAST), and dynamic analysis (DAST). This allows for comprehensive coverage throughout the software development cycle.
Q: How does SAST fit into a DevSecOps pipeline?
A: Static Application Security Testing integrates directly into continuous integration/continuous deployment (CI/CD) pipelines, analyzing source code before compilation to detect security vulnerabilities early in development. This "shift left" approach allows developers to identify and fix problems during the coding process rather than after deployment. It reduces both cost and risks.

https://switchpizza8.bloggersdelight.dk/2025/05/18/comprehensive-devops-and-devsecops-faqs-16/ is a systematized approach that involves storing, disseminating, and rotating sensitive data like API keys and passwords. Best practices include using dedicated secrets management tools, implementing strict access controls, and regularly rotating credentials to minimize the risk of exposure.
Q: Why is API security becoming more critical in modern applications?
A: APIs are the connecting tissue between modern apps, which makes them an attractive target for attackers. Proper API security requires authentication, authorization, input validation, and rate limiting to protect against common attacks like injection, credential stuffing, and denial of service.
Q: How should organizations approach security testing for 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 may find issues sooner, but it can also produce false positives. DAST only finds exploitable vulnerabilities after the code has been deployed. Both approaches are typically used in a comprehensive security program.

API security testing should include authentication, authorization and input validation. Rate limiting, too, is a must. Testing should cover both REST and GraphQL APIs, and include checks for business logic vulnerabilities.
Q: How can organizations reduce the security debt of their applications?
A: Security debt should be tracked alongside technical debt, with clear prioritization based on risk and exploit potential. Organizations should allocate regular time for debt reduction and implement guardrails to prevent accumulation of new security debt.
Q: What is the best practice for securing cloud native applications?
Cloud-native Security requires that you pay attention to the infrastructure configuration, network security, identity management and data protection. Security controls should be implemented at the application layer and infrastructure layer.
Q: How should organizations approach mobile application security testing?
A: Mobile application security testing must address platform-specific vulnerabilities, data storage security, network communication security, and authentication/authorization mechanisms. The testing should include both client-side as well as server-side components.
Q: What role does threat modeling play in application security?
A: Threat modeling helps teams identify potential security risks early in development by systematically analyzing potential threats and attack surfaces. This process should be integrated into the lifecycle of development and iterative.
Q: How can property graphs improve vulnerability detection in comparison to traditional methods?
A: Property graphs create a comprehensive map of code relationships, data flows, and potential attack paths that traditional scanning might miss. By analyzing these relationships, security tools can identify complex vulnerabilities that emerge from the interaction between different components, reducing false positives and providing more accurate risk assessments.
Q: How should organizations approach security testing for event-driven architectures?
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 verify proper event validation, handling of malformed messages, and protection against event injection attacks.
Q: How do organizations implement Infrastructure as Code security testing effectively?
A: Infrastructure as Code (IaC) security testing should validate configuration settings, access controls, network security groups, and compliance with security policies. Automated tools should scan IaC templates before deployment and maintain continuous validation of running infrastructure.
