Large Language Models for Vulnerability Detection
About the Project
As software systems grow in complexity, the need for automated methods to detect vulnerabilities such as buffer overflows, SQL injections, and cross-site scripting becomes increasingly critical. Traditional static and dynamic analysis techniques are often labour-intensive, domain-dependent, and limited in generalisation across codebases.
Recent advancements in Large Language Models (LLMs), such as GPT-4, offer a transformative opportunity to address these limitations. By leveraging their ability to understand and generate structured text, this project aims to explore how LLMs can be trained and fine-tuned to identify, explain, and help mitigate security vulnerabilities in source code across multiple programming languages.
Objectives:
- Model Development and Fine-tuning: Develop and fine-tune LLMs for vulnerability detection using curated datasets of vulnerable and non-vulnerable code.
- Contextual and Multi-language Understanding: Enable LLMs to capture contextual relationships and detect vulnerabilities across diverse programming languages.
- Evaluation and Explainability: Benchmark model performance against existing tools and develop interpretable outputs that provide developers with actionable insights.
- Workflow Integration: Investigate how LLM-based detection can be embedded into CI/CD pipelines for real-time feedback during development.
