## Summary

In recent years, large language models (LLMs) have seen a significant advancement in sophistication, leading to their widespread deployment in critical applications where safety and reliability are paramount. However, along with their capabilities, LLMs also bring inherent risks such as bias, potential for unsafe actions, dataset poisoning, lack of explainability, hallucinations, and non-reproducibility. To address these risks and ensure the responsible use of LLMs, the development of "guardrails" is essential to align these models with desired behaviors and mitigate potential harm. This study delves into the various risks associated with deploying LLMs and evaluates current approaches to implementing guardrails and model alignment techniques. It explores intrinsic and extrinsic bias evaluation methods while emphasizing the importance of fairness metrics for ethical AI development. Additionally, it discusses the safety and reliability considerations for agentic LLMs capable of real-world actions, highlighting the need for testability, fail-safes, and situational awareness. Technical strategies for securing LLMs are presented in a layered protection model operating at external, secondary, and internal levels. The study showcases system prompts, Retrieval-Augmented Generation (RAG) architectures,and techniques to minimize bias and protect privacy as effective measures to enhance LLM security. Effective guardrail design requires a deep understanding of an LLM's intended use case along with relevant regulations and ethical considerations. Striking a balance between competing requirements like accuracy and privacy remains an ongoing challenge in ensuring safe deployment of LLMs in real-world applications. The study underscores the significance of continuous research and development efforts to promote the safe and responsible use of LLMs amidst evolving technological landscapes.
