The Evolving Role of GenAI in Software Development and Application Security

Generative AI (GenAI) is one of the most talked-about and cutting-edge technologies in modern organizations. It's being applied across various sectors, including healthcare, entertainment, finance, and software development.

In the specific case of software development, GenAI is quickly being adopted by developers to assist in writing code. But with the increased interest in embedding security software development life cycle (SDLC), GenAI is beginning to play an increasing role in areas of application security testing, triage, and remediation as well.

The Significance of GenAI in Software Development

GenAI is a sophisticated branch of artificial intelligence that creates new content by learning from existing data sets. Utilizing advanced neural networks and algorithms, GenAI emulates human creativity to generate diverse outputs. It excels at pattern matching, enabling it to identify commonalities in large data collections. Organizations leverage GenAI and underlying large language models (LLMs) to streamline vast amounts of data, making it more accessible and understandable for humans.

Software engineers and developers are increasingly using GenAI Code Assistants to help them write application code. Users of these tools simply provide a prompt (request) for the type of code they need and GenAI generates a response. GenAI has demonstrated the ability to create both common, boilerplate code, as well as more complex functions, all of which frees up developers to focus on higher-level design and problem solving.

GenAI and Application Security

When it comes to application security testing, GenAI’s ability to scrutinize extensive amounts of data (in this case, code) enables it to identify patterns and anomalies. One of its more impactful security uses is in reducing noise (false positives) and prioritizing the issues in the code where human security experts should focus their time and attention.

GenAI has the capacity to automatically generate and execute test cases based on human prompts. It can also simulate a wide range of web traffic scenarios, including edge cases that might be overlooked by human testers, and allow for the identification of bugs and vulnerabilities early in the development cycle.

Furthermore, GenAI can assist in debugging by synthesizing data from multiple sources and helping developers focus on areas of concern. All of this enhances the reliability of the software and reduces the cost and time associated with manual testing and remediation.

Additional use cases include threat detection and response enhanced with the use of GenAI to monitor systems for suspicious activity continuously. Its ability to learn from past security incidents allows it to refine its detection algorithms and predict potential threats with greater accuracy. GenAI can also be used to automate audits, ensuring that software adheres to regulatory standards and minimizing the risk of non-compliance and associated penalties.

Precautions with GenAI

For all its strengths, the use of GenAI in software development and application security does come with some concerns that should not be ignored and there continues to be a real need for humans to audit the code and the fix recommendations that GenAI creates. Whether writing code or recommending a security fix, GenAI makes use of an underlying LLM to generate an answer even when it doesn't have sufficient information. This can sometimes result in "hallucinations"—responses that are inaccurate or nonsensical.

Without oversight, there is also no guarantee that the code provided is secure, or that the fix recommendations will fix a vulnerability. The results may not function as intended, and can potentially introduce new vulnerabilities. GenAI results can be inconsistent as well, in part because they are dependent on the prompts used, and on the quality of the data that the Gen AI model was trained on.

Conclusion

As GenAI continues to evolve, its role in software delivery and security will become increasingly vital. The integration of GenAI with security tools will enable more intelligent and automated security measures, providing robust protection for applications in an increasingly complex digital landscape. This will empower organizations to build and deploy secure software with greater confidence, fostering innovation while mitigating risks.
