In cybersecurity, businesses are increasingly accepting the pivotal role of robust application security measures. A cornerstone in this context is Static Application Security Testing, a method crucial for identifying and mitigating security vulnerabilities in software apps during the development phase. In this article, let’s explore the intricacies of how SAST operates, its advantages, and the array of tools that contribute to building secure software.
Static Application Security Testing: An Introduction
Static Application Security Testing, often termed “white-box testing,” is a preemptive strategy focused on finding vulnerabilities within an app’s source code. Unlike dynamic testing methods assessing applications during runtime, SAST concentrates on the static elements, analyzing codes to find potential security risks before reaching testing or production stages. Numerous vulnerabilities, such as buffer overflows, SQL injections, and XSS, can be found with SAST.
How SAST Works
SAST finds potential vulnerabilities in an app’s coding patterns by analyzing its source code. It methodically compares the code to a predetermined set of guidelines or requirements related to safe coding standards. When it finds a possible vulnerability, it highlights the part of the code that is affected, allowing developers to fix it before the release.
Unveiling SAST Tools
SAST uses both automated and manual methods. Manual SAST involves code reviews by security experts, while automated SAST scans the code, providing a detailed vulnerability report. Several SAST tools offer unique advantages:
- SonarQube: An open-source tool supporting various programming languages, SonarQube facilitates continuous code quality inspection, providing not just SAST capabilities but also code quality metrics.
- Checkmarx: An all-in-one SAST solution working with diverse frameworks and languages, Checkmarx offers precise vulnerability detection, in-depth code analysis, and seamless integration with DevOps tools.
- Fortify: Part of the Micro Focus suite, Fortify provides cloud-based and on-premises SAST solutions. With powerful vulnerability detection, remedial support, and CI/CD pipeline integration, it supports a wide range of programming languages.
- Veracode: A cloud-based SAST solution compatible with various programming languages, Veracode ensures precise vulnerability identification, remedial guidance, and smooth integration with CI/CD pipelines and development tools.

- CodeScan: Tailored for Salesforce development, CodeScan integrates with CI/CD tools, offering thorough code analysis, compliance checks, and vulnerability identification for Apex, Visualforce, and Lightning code.
- GitLab Ultimate: With built-in SAST capabilities supporting multiple languages, GitLab Ultimate seamlessly integrates with CI/CD pipelines, providing vulnerability detection and remedial assistance.
- PVS-Studio: Dedicated to C, C++, C#, and Java, PVS-Studio offers comprehensive code analysis, vulnerability detection, and integration with popular development environments and tools.
- DeepSource: A multi-language code analysis platform, DeepSource provides SAST capabilities, performance improvements, code quality checks, and smooth integration with CI/CD pipelines and version control systems.
Endnote
Static Application Security Testing has become an essential practice, helping organizations to build resilient, secure software. By seamlessly integrating SAST into the development life cycle, businesses can proactively identify and address security vulnerabilities, creating a culture of secure coding. This approach ensures the delivery of robust apps in an interconnected world, where cybersecurity remains vital.
