This method is effective in uncovering security misconfigurations and runtime flaws that may not be visible in static code, making dynamic analysis a crucial component of application security.
DAST plays a crucial role in the overall application security strategy as it complements static testing methods by identifying vulnerabilities that occur in a live environment. By evaluating an application during runtime, DAST provides a more comprehensive view of the application’s security posture, helping to ensure that any potential issues are addressed before they can be exploited in a production environment.
Software Composition Analysis (SCA)
Software Composition Analysis (SCA) tools are essential for managing and securing third-party libraries and open-source components. These tools primarily scan dependencies and package managers to assess the security of open-source components, finding unpatched vulnerabilities that expose organizations to significant risk. By ensuring that all third-party components are secure, SCA tools help maintain the overall security of the software supply chain.
