Large Language Models (LLMs) are widely integrated into modern organizational frameworks, celebrated for their advanced generative abilities. Yet, this integration comes with its share of vulnerabilities, notably to prompt injection attacks. These attacks involve crafting prompts that manipulate the model’s output to generate harmful or inappropriate content. Addressing this critical security concern, a new approach employing embedding-based Machine Learning classifiers has emerged as a potent defense mechanism.
Using three popular embedding models, this method distinguishes between malicious and benign prompts, utilizing the robust capabilities of Random Forest and XGBoost classifiers. This strategy not only enhances the security of LLM applications but also outshines existing solutions that rely solely on encoder-only neural networks.

The effectiveness of this approach promises a safer operational environment for LLM deployments across various sectors. By leveraging sophisticated classifiers, organizations can now more effectively guard against the potentially severe consequences of prompt injection attacks, ensuring the integrity and reliability of their AI-driven systems.
