Question 1

What is the main security problem addressed for LLM-based systems?

Accepted Answer

The article focuses on prompt injection vulnerabilities in systems that use language model interfaces, especially in environments where LLMs process user requests and access sensitive guidance or data.

Question 2

How does the proposed defense detect and mitigate prompt injection attacks?

Accepted Answer

It adds a filter layer that preprocesses incoming requests and post-processes responses. The layer includes a prompt analyzer for input wrapping and an attack validator module that uses an LLM to classify prompts.

Question 3

What security framework levels are discussed to support LLM system protection?

Accepted Answer

The document outlines levels such as privacy compliance, data security, model protection, model integrity, filter layer, monitoring, and standardization/certification to organize and implement cybersecurity controls.
