Input validation, output filtering, and content moderation classifiers.

Mitigating the threat posed by the input module presents a significant challenge for LLM developers due to the diversity of the harmful inputs and adversarial prompts [209], [210].
Reasoning
Input validation mechanism filters harmful and adversarial prompts before model processing.
Defensive Prompt Design
Directly modifying the input prompts is a viable approach to steer the behavior of the model and foster the generation of responsible outputs. This method integrates contextual information or constraints in the prompts to provide background knowledge and guidelines while generating the output [22].
1.2.1 Guardrails & FilteringMalicious Prompt Detection
Different from the methods of designing defensive prompts to preprocess the input, the malicious prompt detection method aims to detect and filter out the harmful prompts through the input safeguard
1.2.1 Guardrails & FilteringMitigation in Language Models
This section delves into mitigating risks associated with models, encompassing privacy preservation, detoxification and debiasing, mitigation of hallucinations, and defenses against model attacks.
1.1 ModelMitigation in Language Models > Privacy Preserving
Privacy leakage is a crucial risk of LLMs, since the powerful memorization and association capabilities of LLMs raise the risk of revealing private information within the training data. Researchers are devoted to designing privacypreserving frameworks in LLMs [226], [227], aiming to safeguard sensitive PII from possible disclosure during humanmachine conservation
1.1 ModelMitigation in Language Models > Detoxifying and Debiasing
To reduce the toxicity and bias of LLMs, prior efforts mainly focus on enhancing the quality of training data and conducting safety training.
1.1 ModelMitigation in Language Models > Hallucination Mitigation
Hallucinations, one of the key challenges associated with LLMs, have received extensive studies.
1.2.9 OtherMitigation in Language Models > Defending Against Model Attacks
Recognizing the significant threats posed by various model attacks, earlier studies [144], [288] have proposed a variety of countermeasures for conventional deep learning models. Despite the advancements in the scale of parameters and training data seen in LLMs, they still exhibit vulnerabilities similar to their predecessors. Leveraging insights from previous defense strategies applied to earlier language models, it is plausible to employ existing defenses against extraction attacks, inference attacks, poisoning attacks, evasion attacks, and overhead attacks on LLMs.
1.2.4 Security InfrastructureMitigation in Toolchain Modules
Existing studies have designed methods to alleviate the security issues of tools in the lifecycle of LLMs. In this section, we summarize the mitigations of those issues according to the categories of tools

Despite their impressive capabilities, large lan- guage models (LLMs) have been observed to generate responses that include inaccurate or fabricated information, a phenomenon com- monly known as “hallucination”. In this work, we propose a simple Induce-then-Contrast De- coding (ICD) strategy to alleviate hallucina- tions. We first construct a factually weak LLM by inducing hallucinations from the original LLMs. Then, we penalize these induced hallu- cinations during decoding to enhance the fac- tuality of the generated content. Concretely, we determine the final next-token predictions by amplifying the predictions from the orig- inal model and downplaying the induced un- truthful predictions via contrastive decoding. Experimental results on both discrimination- based and generation-based hallucination eval- uation benchmarks, such as TruthfulQA and FACTSCORE, demonstrate that our proposed ICD methods can effectively enhance the factu- ality of LLMs across various model sizes and families. For example, when equipped with ICD, Llama2-7B-Chat and Mistral-7B-Instruct achieve performance comparable to ChatGPT and GPT4 on TruthfulQA, respectively.
