Conﬁguring a secure Large Language Model (LLM) for automated log analysis requires establishing high-level instructions that dictate the model's persona and safety boundaries. During the development of a security-focused chatbot, the team needs to ensure the model remains in "analyst mode" and refuses to provide administrative credentials, even if a user attempts to bypass standard ﬁlters. Which of the following approaches BEST utilizes the provided architecture to enforce these behavioral constraints?

Answer options

Correct Answer:

Explanation

The system prompt is a set of high-level instructions provided to an LLM before any user input. It is the standard and most effective method for defining the model's persona, operational boundaries, and safety guardrails. By configuring the system prompt to state that the model is a "security analyst" and must "never reveal administrative credentials," the team directly enforces the required behavioral constraints at the core of the model's operation for that session.

Why Incorrect

A. Homomorphic Encryption protects data privacy during processing but does not influence or control the behavioral output of the LLM.

C. Adjusting the temperature parameter controls the randomness of the output, not the adherence to fundamental operational rules or safety policies.

D. RBAC controls user access to the model, not the internal behavior of the model itself during an inference session.
