What are SAST Tools? Working Principles

Source code security analysis tools (SAST - Static Application Security Testing) are tools that analyze the source code of an application without running the compiled application to detect security vulnerabilities. These tools identify security problems in the early stages of the development process, preventing more costly and time-consuming remediation processes. SAST tools detect potential vulnerabilities, coding errors, and non-compliance with security standards by performing a static analysis of the code.

SAST tools can support different programming languages and coding standards. These tools generally follow these steps:

1. Parsing the Source Code: The SAST tool converts source code into an analyzable format.
2. Rule Based Analysis: Code is scanned using predefined security rules and patterns.
3. Data Flow Analysis: Potential security risks are identified by monitoring the movement of data within the application.
4. Vulnerability Detection: Identified vulnerabilities are reported and fix recommendations are provided to developers.
5. Reporting: Analysis results are presented in detailed reports so developers can easily understand and resolve issues.

SAST tools can often be integrated into automated testing processes and used in continuous integration/continuous deployment (CI/CD) pipelines. This way, every code change is automatically scanned for security, preventing new vulnerabilities from being introduced. This integration reduces the risk of security breaches and makes the software development process more secure.

SAST tools not only detect vulnerabilities but also help developers secure coding Thanks to the analysis results and recommendations, developers can learn from their mistakes and develop more secure applications. This increases the overall quality of the software in the long run.

Key Features of SAST Tools

Key features of SAST tools include language support, rule customization, reporting capabilities, and integration options. A good SAST tool should provide comprehensive support for the programming languages and frameworks used, allow customization of security rules, and present analysis results in easily understandable reports. It should also be able to seamlessly integrate with existing development tools and processes (IDEs, CI/CD pipelines, etc.).
