PTC: Prefix Tuning CodeT5 for High-Quality Secure Network Measurement Script Generation

The automated generation of secure network measurement scripts is vital for reliable network operations, but traditional models often neglect security, leading to vulnerabilities like command injection and buffer overflows. We propose PTC (Prefix Tuning CodeT5), a novel method leveraging prefix tuning on the CodeT5 model to generate secure, functionally correct scripts without full retraining. PTC introduces a security-oriented loss function to enhance code correctness and security compliance, reducing vulnerabilities while meeting functional requirements. We evaluate PTC on several groups of targets, and results show that our solution outperforms baseline models, producing secure and functional network measurement scripts across various scenarios. This approach effectively bridges the gap between code generation and security, offering a practical solution for developing robust network tools for real-world applications.
