Application Security FAQs

Q: What is application security testing and why is it critical 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: Where does SAST fit in 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. Q: Why is API security becoming more critical in modern applications? A: APIs serve as the connective tissue between modern applications, making them attractive targets for attackers. To protect against attacks such as injection, credential stuffing and denial-of-service, API security must include authentication, authorization and input validation. 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. A comprehensive security program typically uses both approaches. Q: How can organizations effectively implement security champions programs? A: Security champions programs designate developers within teams to act as security advocates, bridging the gap between security and development. Programs that are effective provide champions with training, access to experts in security, and allocated time for security activities. Q: What is the role of property graphs in modern application security today?
