What advantage does using a Lambda function provide when launching CodePipeline SAST tools?

Using a Lambda function when launching CodePipeline SAST (Static Application Security Testing) tools allows for fast custom testing because Lambda is designed to execute code in response to events from AWS services, which can lead to a more streamlined testing workflow.

When utilizing Lambda functions, developers can create custom scripts that can rapidly initiate scans and handle specific testing scenarios tailored to their applications' unique requirements. This quick and efficient execution is beneficial in CI/CD (Continuous Integration/Continuous Deployment) pipelines, where speed is crucial for maintaining rapid development cycles. By enabling on-demand execution, Lambda functions enhance the capability to perform tests without the overhead of managing a full server infrastructure, allowing for quicker feedback on code vulnerabilities.

This agility in creating custom tests not only improves the responsiveness of the development process but also ensures that security assessments can be seamlessly integrated into the overall software development lifecycle, helping identify vulnerabilities early and address them promptly.
