Enhancing LLM Security: Vulnerabilities, Threats, and Mitigation Strategies

Large Language Models (LLMs) are revolutionizing industries by automating tasks and improving various applications. However, the widespread adoption of LLMs has exposed critical security vulnerabilities that malicious actors exploit to launch sophisticated attacks. Understanding these vulnerabilities, emerging threats, and best practices is essential for ensuring the security and integrity of LLM deployments.

Background and Context of LLM Security

The development of Large Language Models (LLMs) has evolved significantly, especially with the rise of deep learning and transformer architectures. Models like BERT and GPT-3 have set new standards for natural language understanding. As LLMs expand into multimodal learning, the security risks associated with them have also increased, including prompt injection attacks and data poisoning.

Today, the threat landscape for AI systems reveals a rise in sophisticated attacks targeting LLMs. Sectors like healthcare and finance face unique vulnerabilities due to regulatory compliance requirements and the sensitivity of their data. Robust security frameworks are crucial to address these evolving threats and protect LLM deployments.
