The Open Web Application Security Project (OWASP) has released a guide to securing large language models (LLMs), which are driving forces behind many digital tools. The OWASP Top 10 for LLMs offers developers, cybersecurity experts, and AI researchers strategies to identify and mitigate vulnerabilities in these models. These include safeguarding against prompt injection, ensuring secure output handling, preventing data and model poisoning, protecting against Denial of Service (DoS) attacks, addressing supply-chain vulnerabilities, designing secure plugins with care, minimizing sensitive information disclosure, limiting excessive agency in LLMs, avoiding overreliance on LLMs, and securing models against theft.

The article discusses seven techniques for evaluating and monitoring the performance of large language models (LLMs). These techniques include LLM-as-a-Judge, ML-model-as-Judge, Embedding-as-a-source, NLP metrics, Pattern recognition, End-user in-the-loop, and Human-as-a-Judge. Each technique has its pros and cons, and the choice of which one to use depends on factors such as cost, latency, setup, explainability, etc. The article also provides a comparison chart for these techniques and offers insights into how they can be used in combination to provide a more comprehensive understanding of LLM performance.

Large language models (LLMs) often provide inconsistent responses over time due to changes in user behavior, system behavior, or real-world phenomena. Distinguishing between these causes can be challenging without strong monitoring tools. The article presents four scenarios demonstrating how these issues may present themselves and provides methods for monitoring them. These include detecting changes in input data (Scenario A), identifying system behavior change (Scenario B), diagnosing changes in predictive model performance (Scenario C), and recognizing fundamental changes in the real world (Scenario D). The article emphasizes the importance of effective monitoring solutions that can identify and distinguish between these different causes.
