Introduction: How SAST is Crucial for Application Security
Security is the top priority in any software development. Static Application Security Testing (SAST) is one of the most effective ways to catch vulnerabilities early. It scans code before it runs, ensuring no hidden risks go unnoticed. SAST analyzes both source code and binary code, providing two layers of defense at different stages of development. In this guide, we’ll explain how SAST works for each type of code and why using both methods strengthens your security strategy.
Source Code Analysis With SAST: What It Is and How It Works
What is a Source Code?
Source code is the readable part of the software that developers write. It’s the backbone of the application and controls how it behaves. Unfortunately, security issues like SQL injection and cross-site scripting (XSS) often appear here.
How SAST Scans Source Code?
SAST tools scan raw, uncompiled source code for security flaws. This process is static, meaning it doesn’t run the code but instead looks for vulnerabilities in its structure. Tools like SonarQube and Checkmarx search for patterns in the code, flagging issues like hardcoded passwords or improper input handling.
Steps:
- Pattern Matching: The tool checks the code for common insecure patterns.
- Vulnerability Detection: It highlights risky code sections, such as unvalidated inputs.
- Detailed Reports: After the scan, the tool generates a report with solutions to fix the issues.
Example:
Imagine a login function that doesn’t sanitize user input. A SAST tool would flag this as a risk for SQL injection, allowing developers to address it before release.
Benefits of Source Code Analysis
- Early Detection: Catch issues early and avoid costly fixes later.
- Improved Code Quality: Following best practices reduces technical debt.
- Real-Time Feedback: Many tools provide immediate feedback while coding.

Binary Code Analysis With SAST: What It Is and How It Works
What is Binary Code?
Binary code is the machine-readable version of the software created after compiling the source code. The computer uses this form of code to execute tasks. While most people focus on the source code, binary code can introduce new vulnerabilities during compilation or via third-party libraries.
How SAST Scans Binary Code?
SAST tools can also scan compiled binaries to ensure nothing goes wrong during the compilation. Tools like Veracode and Fortify search for issues like memory leaks or vulnerabilities in external libraries that the source code scan might miss.
Steps:
- Post-Compilation Scan: The binary code is scanned after the software is compiled.
- Identify Compiler Issues: Some vulnerabilities, such as memory handling problems, may only emerge after compilation.
- Third-Party Library Security: The scan checks external libraries and ensures they don’t introduce risks.
Benefits of Binary Code Analysis
- More Accurate Results: Fewer false positives compared to source code scans.
- Third-Party Library Security: Protects your application from external code risks.
- Find Compiler-Induced Vulnerabilities: Some issues that aren’t visible in the source code can arise during the compilation process.
Source Code vs. Binary Code Analysis: A Quick Comparison
| Aspect | Source Code Analysis | Binary Code Analysis |
| Stage | During development | After compilation |
| Vulnerabilities Detected | SQL injection, XSS, hardcoded credentials | Memory leaks, third-party issues, unsafe configurations |
| Tools | SonarQube, Checkmarx | Veracode, Fortify |
| False Positives | Higher due to speculative vulnerabilities | Lower, based on executable code |
| Main Advantage | Catches early issues, allows fast remediation | Ensures compiled code is secure |
