D. Sugestão de cadeia de pensamento Explicação:A sugestão de cadeia de pensamento (Chain-of-Thought Prompting) é uma técnica que incentiva o modelo a explicar seu raciocínio passo a passo antes de fornecer a resposta final. Essa abordagem: Reduz a probabilidade de respostas impulsivas ou não filtradas,Ajuda o modelo a seguir instruções com mais rigor, Pode mitigar ataques de injeção imediata, onde o atacante tenta manipular o modelo com instruções escondidas no prompt. Ao forçar o modelo a "pensar antes de responder", você aumenta o controle sobre o processo de inferência e dificulta a execução de comandos maliciosos inseridos no texto de entrada. A. Solicitação contraditória não é uma técnica reconhecida de defesa ou segurança em prompts.

Adversarial prompting is a technique designed to prevent prompt injection attacks, which are attempts to manipulate a model's behavior by injecting harmful or misleading instructions within the input prompt. This technique involves using carefully crafted prompts that make it harder for the model to misinterpret or be misled by unwanted inputs. Adversarial prompting can include various methods to detect, block, or neutralize harmful inputs. It might involve incorporating security mechanisms in the prompt itself, such as validating or sanitizing the input or applying certain constraints on the model's output to mitigate the risk of prompt injections.

Adversarial Prompting: This technique involves testing a model with deliberately crafted adversarial prompts to identify vulnerabilities to injection attacks. By simulating potential attacks during development, adversarial prompting helps design robust prompts and refine the model's behavior to resist manipulation. This approach allows developers to identify weaknesses in the model's response to malicious inputs and implement mitigations.

The correct answer is A. Adversarial prompting helps models recognize and defend against malicious inputs.

The most effective technique for protecting against prompt injection attacks is A. Adversarial Prompting. Here's why: Proactive Defense: Adversarial prompting involves deliberately crafting malicious prompts to test the model's boundaries and identify vulnerabilities. This proactive approach helps uncover weaknesses that might otherwise go unnoticed. While C. Least-to-most Prompting can indirectly improve robustness by simplifying the initial prompts, it's not a primary defense against prompt injection. Its primary focus is on improving task completion, not directly addressing malicious inputs. Key takeaway: Adversarial prompting is the most direct and effective method for enhancing the security of language models against prompt injection attacks.

Adversarial prompting involves designing and testing prompts to identify and mitigate vulnerabilities in an AI system. By exposing the model to potential manipulation scenarios during development, practitioners can adjust the model or its responses to defend against prompt injection attacks. This technique helps ensure the model behaves as intended, even when malicious or cleverly crafted prompts are used to bypass restrictions or elicit undesirable outputs.
