Fortify and static code analysis

#1
05-09-2022, 03:12 PM
I often find it interesting to look back at the history of Fortify, especially for those of us who work in application security. It started out as a company in 2003, focusing on code security for software development. Fortify's flagship product, Fortify Source Code Analyzer, emerged to address the growing need for static application security testing (SAST). With vulnerabilities like buffer overflows and SQL injection becoming prevalent, developers needed more robust tools to mitigate risks early in the software development lifecycle. In 2010, Micro Focus acquired Fortify Technologies, incorporating this capability into a broader portfolio aimed at providing comprehensive enterprise solutions. The acquisition allowed Fortify's technologies to integrate with various platforms and services, thus enhancing its adaptability across different environments.

Technical Features of Fortify
I find it crucial to discuss the technical capabilities of Fortify beyond just its history. Fortify Source Code Analyzer employs static analysis techniques that examine both the code itself and the context within which it executes. It parses code to identify vulnerabilities like insecure data handling or improper authentication algorithms. One of its notable features is its capability to support multiple languages, including Java, C#, C, C++, and even some scripting languages. The tool provides contextual information, making vulnerability reports not just informative but actionable. Additionally, it includes 'SmartScan' technology, which allows you to tailor scans to focus on specific areas or types of vulnerabilities, thereby increasing efficiency.

Integration with CI/CD Pipelines
For developers, integration into CI/CD pipelines represents a game-changer. Fortify succeeds in this area, allowing you to incorporate its scanning capabilities directly into your build processes. Via plugins for popular CI/CD tools like Jenkins and Azure DevOps, you can automate the scanning of code every time you merge a pull request. This integration allows immediate feedback during the development process. Reports generated can tie back to specific lines of code, which helps you track down vulnerabilities without sifting through mountains of data. Another advantage is that you can generate both detailed and high-level reports, so whether you need a deep dive for developers or an executive summary for stakeholders, Fortify delivers.

Comparative Platforms: Fortify vs. SonarQube
Comparing Fortify with other platforms, such as SonarQube, reveals essential differences in focus areas. SonarQube generally emphasizes code quality, offering metrics and insights into maintainability, security vulnerabilities, and code smells. In contrast, Fortify's primary aim centers on security vulnerabilities. While SonarQube can detect some security issues through its security plugins, its capabilities are not as extensive as Fortify's dedicated SAST functionalities. With Fortify, you're more likely to catch a diversified set of vulnerabilities upfront. However, SonarQube's strength lies in its community-driven nature, which can lead to rapid updates and broader language support via plugins. You could even use both in tandem, considering SonarQube for code quality and Fortify for stringent security checks.

Accuracy and False Positives
You will naturally ponder the accuracy of static analysis tools, especially regarding false positives. In my experience, Fortify provides detailed and context-rich vulnerability reports, but you might occasionally encounter false positives that require further investigation. The tool uses heuristics that consider the application context, which aids in refining results, yet no static analyzer is infallible. Analyzing the results requires additional expertise, as some vulnerabilities might be trivial based on how your application handles specific cases. Some teams favor manual code reviews for complex areas post-automated scans, which can enhance reliability. Balancing automated analysis with human insight allows you to utilize Fortify to its fullest advantage.

Usability and Learning Curve
The user interface of Fortify is relatively straightforward, provided you have prior experience with similar tools. I have noticed that first-time users may feel overwhelmed by the plethora of options and configurations available. The learning curve can range depending on your familiarity with static analysis processes and the specific language configurations used in your organization. Training resources, such as webinars and documentation, are fairly comprehensive, which I encourage you to utilize. As you get acquainted, you will appreciate how customizable the tool can be, allowing you to align it closely with your organization's security policies, though this also means taking the time to configure it optimally.

Privacy and Handling Sensitive Data
Another important area relates to how Fortify handles sensitive data during analysis. With GDPR and other data privacy regulations in mind, it's worth noting that Fortify can analyze codebases without affecting sensitive information if set up correctly. You need to configure it to ignore specific sensitive data or repositories that contain such code. It's crucial to keep in mind that while the tool can work locally or on-premises, many organizations lean towards cloud-based solutions. Thus, if your team opts for a cloud deployment, ensure you fully understand how sensitive data manages within that context. Proper configuration can both elevate your security posture and comply with data regulations, and Fortify provides methods to facilitate that while allowing you to run your scans.

Future Considerations and Trends in Static Analysis
Looking toward the future, trends in static analysis are evolving as the industry seeks to balance speed and security. You may see the incorporation of machine learning algorithms that can improve detection rates and reduce false positives over time. Fortify and other vendors are likely to embed intelligence into their tools that proactively learn from past scans. The introduction of dynamic analysis tools could also become more commonplace, allowing for a deeper inspection during runtime. As methodologies like DevSecOps become the norm, the role of traditional SAST tools will continue to shift. You'll need to remain adaptable, continuously assessing whether Fortify or similar products align with your changing requirements as threats evolve and your codebase grows.

I think you'll find that discussing Fortify and static code analysis brings a wealth of topics to consider, such as technical specifications, integration, and future developments that shape the application security field. Each of these points can really enhance your security regime or provide you with the grounds to select the most fitting tools for your team's specific needs.
