Source Code Vulnerability Review

One way to ensure application security is to perform security analysis of the source code. There are various methods of analysis, but two of the most popular are DAST (Dynamic Application Security Testing) and SAST (Static Application Security Testing). While both of these methods aim to identify vulnerabilities in applications, they differ in approach and scope.

Comparison of DAST and SAST

1. Definition:
   • DAST: This is a testing technique that analyzes an application as it runs, focusing on identifying vulnerabilities that can be exploited in real-world attacks.
   • SAST: This is the process of analyzing the source code, bytecode or binary code of an application to identify vulnerabilities without running the program.
2. Time to carry out:
   • DAST: Performed while the application is running.
   • SAST: Performed during the code development phase, before the application is launched.
3. Scope:
   • DAST: Focuses on the application runtime environment, identifying vulnerabilities that can be exploited by an attacker.
   • SAST: Analyzes source code, bytecode or binary code for vulnerabilities.
4. Benefits:
   • DAST: Can identify vulnerabilities that are difficult to detect in static analysis, such as configuration problems or runtime errors.
   • SAST: Can detect vulnerabilities early in the software development process, allowing for quick fixes.
5. Disadvantages:
   • DAST: May fail to detect certain vulnerabilities that are only visible in the source code.
   • SAST: Can generate false alarms and requires in-depth analysis of results by specialists.

In summary, both DAST and SAST have their place in the application security process. The choice of the appropriate method depends on the specifics of the project, available resources and the level of risk associated with the application. In many cases, it is recommended to use both methods simultaneously to ensure comprehensive protection.
The analysis of application source code is carried out on the basis of best practices in the area of secure software development and recommendations of the OWASP organization (ASVS and MASVS standard).
The analysis of the source code can be supported by the results of the penetration tests performed.

Service Description:

As part of our work, we will complete a static analysis of the source code, which will address the most relevant functionality from a security perspective, including:

• Application input and output support,
• Data Validation,
• Authentication and authorization,
• Cryptographic mechanisms,
• Memory management,
• Error handling,
• Operating system references,
• Login.

According to the methodology, our code reviews are performed in the following stages:

• Interview the application’s architects or lead developers to obtain information about its business functions and internal structure,
• Clean up the source code from test code and unused code fragments, as well as mark up the codes of external libraries,
• Perform static code analysis with automated tools to identify vulnerabilities detected by these tools,
• Manual verification of results obtained from automated tools,
• Supplement the analysis with manual checks based on checklists describing different types of vulnerabilities adequate for the programming language used,
• Discuss the results of the work with application architects or lead developers to determine the level of vulnerability risk and the development team’s approach,
• Prepare a report containing a list of identified vulnerabilities with recommendations for their removal.
