Aikido Security: Best all-in-one Application Security Platform
SAST helps developers build more secure software. This list of tested options provides a starting point to explore and compare tools.
What is Static Application Security Testing (SAST)?
Static application security testing (SAST) is used to secure software against software vulnerabilities in your source code. It uses static analysis to review code and performs automated code inspection to identify vulnerabilities without executing the programs without any human code review.
In contrast to dynamic application security testing (DAST), which focuses on black-box testing of the functionality of a running application, SAST tools focus on the software's source code via white-box testing. These vulnerabilities include SQL injection, the OWASP Top 10 security risks, buffer overflows, leaking API keys, and more.
SAST is only possible when the code is fully available, for example, by sharing access to your Git repository, which can be as simple as connecting SAST tools to your Github, Gitlab, or Bitbucket account. Static analysis tools can detect 50% of existing security vulnerabilities in minutes.
As part of your entire development lifecycle, SAST is the first step to secure your application at a code security level. SAST is a great way to perform software quality assurance, even if many false-positive vulnerabilities prevent developers from enjoying the tools fully.
SAST tools enable development teams to focus on developing and delivering software; they reduce the risk of downtime of applications and prevent the leaking of private information stored in your software.
SAST tools are key in implementing the shift-left security concept. It will help you conduct security testing sooner in the application development process (SDLC). In contrast to traditional DevOps, where security & monitoring would come after the release in production, SAST tools monitor your application for insecure code before being deployed.
