Static Application Security Testing (SAST)

1. Introduction

Static Application Security Testing (SAST) is a method of debugging by examining the source code before the program is run. It helps identify vulnerabilities early in the development cycle, ensuring that security flaws are addressed before code is deployed.

2. Key Concepts

• **Source Code Analysis**: Analyzing the source code without executing it.
• **Early Detection**: Finding vulnerabilities during the coding phase.
• **Integration**: Integrating SAST tools into CI/CD pipelines.
• **False Positives**: Understanding and managing false positives in reports.

3. Step-by-Step Process

The following flowchart outlines the typical SAST process:

graph TD;
    A[Start] --> B[Run SAST Tool];
    B --> C{Find Vulnerabilities?};
    C -- Yes --> D[Generate Report];
    C -- No --> E[End];
    D --> F[Remediate Vulnerabilities];
    F --> B;
    E --> G[End];
            

Here’s a more detailed explanation of each step:

1. Run SAST Tool: Use an automated tool to analyze the source code.
2. Find Vulnerabilities: The tool identifies potential security issues.
3. Generate Report: A report is created listing the identified vulnerabilities.
4. Remediate Vulnerabilities: Developers address the security issues identified in the report.

4. Best Practices

To maximize the effectiveness of SAST, consider the following best practices:

• Integrate SAST into the CI/CD pipeline for continuous scanning.
• Regularly update SAST tools to identify new vulnerabilities.
• Provide training for developers on secure coding practices.
• Review and prioritize the vulnerabilities based on risk and impact.
