SAST is able to be integrated into the continuous integration and continuous deployment (CI/CD) that allows development teams to ensure security is an integral part of the development process. This article focuses on the importance of SAST for security of application. It also examines its impact on developer workflows and how it helps to ensure the achievement of DevSecOps. Application Security: A Changing Landscape Security of applications is a key concern in today's digital world that is changing rapidly. This is true for organizations that are of any size and sectors. Security measures that are traditional aren't sufficient due to the complexity of software and advanced cyber-attacks. The need for a proactive, continuous, and integrated approach to security of applications has led to the DevSecOps movement. DevSecOps is a fundamental shift in software development. Security is now seamlessly integrated at every stage of development. DevSecOps allows organizations to deliver quality, secure software quicker by breaking down divisions between operations, security, and development teams. The core of this change is Static Application Security Testing (SAST). Understanding Static Application Security Testing SAST is an analysis technique used by white-box applications which does not execute the application. It scans code to identify security vulnerabilities such as SQL Injection as well as Cross-Site Scripting (XSS) and Buffer Overflows, and many more. SAST tools make use of a variety of methods to spot security weaknesses in the early phases of development such as the analysis of data flow and control flow. SAST's ability to detect weaknesses earlier in the development cy
