In our next section, we will delve into the specific challenges and unveil effective risk management strategies associated with LLM security, providing insights that are crucial for navigating the dynamic and evolving landscape of language model applications.

LLM Security Challenges and Risk Management

To manage the risks associated with LLMs, first we need to identify the primary threats to LLM security. In this section we will discuss the security challenges, potential risks and how to mitigate them in the following sections.

Identifying Security Challenges

  • Data Breaches: The security implications associated with data breaches in the context of Large Language Models (LLMs) are of significant concern. Unauthorized access to the extensive datasets underpinning these models poses a considerable threat, potentially resulting in severe privacy infringements and intellectual property theft. Given the sensitive nature of the data involved, often encompassing personal information or proprietary content, the potential impact of breaches is heightened. Consequently, prioritizing measures to safeguard against unauthorized access is imperative to preserve the integrity of both individual privacy and valuable intellectual property.

**💡Pro Tip: Learn about the critical role of Personally Identifiable Information (PII) in today's AI-driven digital world. **

  • Model Manipulation: The risk of model manipulation introduces a nuanced challenge, wherein adversaries may attempt to exploit trained LLMs to produce biased or harmful results. Manipulating model outputs could lead to the dissemination of misinformation, reinforcement of harmful stereotypes, or the generation of content with malicious intent. For example, adversaries may attempt model inversion to reconstruct sensitive or private information about the input data that was used to train the LLM.

  • Infrastructure Vulnerabilities: Infrastructure vulnerabilities present a tangible risk, encompassing potential exploits on the hardware and networks supporting LLMs. These vulnerabilities could lead to service disruptions, unauthorized model access, or even compromise the integrity of the model itself.

  • Ethical and Legal Risks: Navigating the ethical and legal landscape is a critical challenge in LLM security. Ethical concerns may arise from biased outputs. For example, if an LLM is trained on biased or discriminatory datasets, it may inadvertently generate content that reflects or amplifies those biases. This risk underscores the importance of ethical considerations in curating diverse and representative training data and implementing measures to detect and mitigate biases in LLM outputs.

**💡Pro Tip: Explore the essentials of Responsible AI. Learn about accountability, privacy, and industry standards. **
Legal risks could stem from the inadvertent generation of content that violates regulations or infringes upon intellectual property rights. For instance, if an LLM generates content that violates privacy laws by disclosing sensitive information, the deploying entity may face legal repercussions. Moreover, issues of intellectual property infringement may arise if the model generates outputs that replicate proprietary content.

Risk Considerations in LLM Deployment

A proactive approach to risk assessment, including vulnerability anticipation and consideration of potential adversarial scenarios, is pivotal for addressing these implications. By identifying and mitigating risks before deployment, organizations can enhance the robustness of their LLMs, safeguard operational integrity, maintain user trust, and adhere to regulatory standards.

Proactive Risk Assessment

  • Anticipate Vulnerabilities: This involves assessing potential weak points in the model. For instance, understanding the model's susceptibility to adversarial attacks, where deliberately crafted inputs could lead to biased or unintended outputs.

**🛡️ Discover how Lakera’s Red Teaming solutions can safeguard your AI applications with automated security assessments, identifying and addressing vulnerabilities effectively.**

  • Adversarial Scenarios: Considering adversarial scenarios entails envisioning potential threats. For example, if an LLM is deployed in a chatbot for customer service, anticipating scenarios where malicious users attempt to manipulate the model with deceptive inputs helps prevent the system from misuse.

    LLMs can fall prey to problems like model inversion attacks, where adversaries aim to extract sensitive information from a deployed model by leveraging its outputs. Through the submission of queries and analysis of responses, attackers seek to uncover insights into confidential data used during training, such as private images or personally identifiable information. RAPT is a recently proposed privacy preserving prompt tuning method for LLMs that aims to safely use private input data for guiding LLM outputs (overview shown below).
Overview of RAPT (Source)

Implications of Risks

  • Operational Integrity: Risks affecting operational integrity can be illustrated by the possibility of infrastructure vulnerabilities. If the servers hosting an LLM are not adequately secured, unauthorized access to model parameters and architecture may compromise the model's availability or lead to service disruptions.
  • User Trust: Biased outputs exemplify risks impacting user trust. If an LLM, due to biased training data, consistently produces outputs that favor certain perspectives, users may lose trust in the model's objectivity, affecting its credibility and acceptance.
  • Regulatory Compliance: Consider the risk of legal consequences arising from ethical breaches. For instance, if an LLM generates content that violates data privacy regulations by unintentionally revealing sensitive information, it could lead to regulatory penalties and harm the reputation of the company employing the model.

Fundamental Risk Management Strategies

  • Regular Audits: Developing LLM auditing procedures is an important and timely task for two reasons. First, LLMs pose many ethical and social challenges, including the perpetuation of harmful stereotypes, the leakage of personal data protected by privacy regulations, the spread of misinformation, plagiarism, and the misuse of copyrighted material. Recently, the scope of impact from these harms has been dramatically scaled by unprecedented public visibility and growing user bases of LLMs. For example, ChatGPT attracted over 100 million users just two months after its launch.
    Second, LLMs can be considered proxies for other foundation models. Consider CLIP, a vision-language model trained to predict which text caption accompanied an image, as an example. CLIP too displays emergent capabilities, can be adapted for multiple downstream applications, and faces similar governance challenges as LLMs. The same holds of text2image models such as DALL·E 2. Developing feasible and effective procedures for how to audit LLMs is therefore likely to offer transferable lessons on how to audit other foundation models and even more powerful generative systems in the future.
  • Incident Response Planning: Encouraging the development of a robust incident response plan is crucial to effectively address security breaches or issues that may arise during LLM deployment. This strategy involves creating a detailed guidebook outlining the steps to be taken in the event of a security breach. Drawing from the proactive risk management information, incident response plans should be updated to specifically address LLM incidents. For example, the plan could include steps to counteract potential model exploitation or mitigate risks associated with adversarial attacks on LLM-generated content.

**💡Pro Tip: Explore the complex world of Adversarial Machine Learning where AI's potential is matched by the cunning of hackers.**

  • Adopting Security Best Practices: Suggesting the alignment of LLM operations with established security best practices is a foundational strategy. Reference can be made to the information provided on AI Asset Inventory, emphasizing the importance of cataloging AI components and applying the Software Bill of Material (SBOM) to ensure comprehensive visibility and control over all software components. Aligning with OWASP’s guidelines on security best practices ensures that the organization incorporates industry-recognized measures into their LLM deployment, enhancing security posture and reducing the risk of potential threats.

**💡Pro Tip: Discover how Lakera's security solutions correspond with the OWASP Top 10 to protect Large Language Models.**

In essence, comprehending and effectively managing the risks associated with Large Language Models (LLMs) is imperative for maintaining secure operations. Whether addressing adversarial risks, ensuring ethical considerations, or navigating legal and regulatory landscapes, a proactive stance toward risk management is key.

While there are several challenges that are inherent to LLM security, adopting established security practices that align with the problem at hand can create a robust defense to known problems. Let us discuss this in more detail in the next section.

Integrating Established Security Practices

While LLM security might look like a daunting task, its alignment with traditional cybersecurity principles make it easier to protect language model systems. Albeit, unique considerations specific to LLMs need to be made where necessary, but incorporating established cybersecurity practices gives a good starting point to protect LLM deployment pipelines.

Alignment with Traditional Cybersecurity

LLM security is similar to traditional cybersecurity in several aspects:

  • Data Protection: The fundamental need to protect sensitive data is a shared principle between LLM security and traditional cybersecurity. For instance, just as in traditional cybersecurity, encrypting data inputs and outputs is crucial to prevent unauthorized access and ensure confidentiality.
  • Network Security: Ensuring the integrity and security of network connections is a commonality. LLMs, like any other system, benefit from robust network security practices. For instance, implementing firewalls and intrusion detection systems helps mitigate potential threats in the communication channels.
  • User Access Controls: Managing and controlling user access is a universal aspect. Standard practices, such as role-based access control (RBAC), play a vital role in both traditional cybersecurity and LLM security. Proper access controls prevent unauthorized users from manipulating or exploiting the language model.

Applicability of Standard Cybersecurity Practices:

  • Encryption: The use of encryption techniques to secure data in transit and at rest is a cornerstone of traditional cybersecurity. Similarly, encrypting data processed by LLMs safeguards against unauthorized interception and ensures the confidentiality of sensitive information.
  • Secure Coding Practices: Adhering to secure coding practices is not exclusive to traditional applications; it is equally crucial in the LLM landscape. Proper coding practices help mitigate vulnerabilities that could be exploited, reinforcing the overall security posture of language models.
  • Regular Security Audits: Auditing is a governance mechanism that technology providers and policymakers can use to identify and mitigate risks associated with AI systems. Periodic security audits are essential in both cybersecurity and LLM security systems. Conducting regular audits on LLM systems allows for the identification of vulnerabilities and weaknesses that may pose security risks if left unaddressed. An example of a method to perform security audits on LLMs has been proposed in this paper.

Unique Aspects of LLM Security


This paper performed a systematic study of prompt injection attacks and also proposed a defense framework against such attacks using 10 LLMs across 7 tasks. The authors propose two defense strategies, namely prevention and detection, to defend against prompt injection attacks. In particular, given a data prompt, they try to remove the injected instruction/data from it to prevent prompt injection attacks. They can also detect whether a given data prompt is compromised or not. Additionally, the authors combined these two defense strategies to form a prevention-detection framework. These defenses can be deployed by an LLM-Integrated Application or the backend LLM.

LLMs also face ethical issues for generating content. Stemming from pretraining on extensive datasets, LLMs are known to exhibit concerning behaviors such as generating misinformation, biased outputs, etc. While GPT-4 exhibits reduced hallucination and harmful content generation (according to OpenAI) it still reinforces social biases and may introduce emergent risks like social engineering and interactions with other systems. LLM-integrated applications, for example by Bing Chat (Microsoft), have faced public concerns due to unsettling outputs, prompting limitations on the chatbot's interactions. Instances of factual errors, blurred source credibility, and automated misinformation have occurred in search-augmented chatbots, emphasizing the need for vigilant risk mitigation strategies in LLM applications.

  • Dynamic Nature of LLMs: Unlike static models, LLMs evolve over time, refining their language capabilities and adapting to new information. This constant evolution poses challenges for traditional security measures, requiring strategies that can dynamically respond to emerging threats and vulnerabilities. The need for real-time monitoring, rapid updates, and flexible security protocols becomes crucial in safeguarding LLMs against evolving risks.
    Dynamic Application Security Testing (DAST) is a test that is conducted from an end-user standpoint to identify malicious activities and potential attacks. This testing methodology involves executing security test cases during the application's runtime, enabling the discovery of runtime issues. With a reduced likelihood of false positives, DAST analyzes requests and responses in their actual state. DAST, which is a type of BlackBox testing, operates akin to an external attacker or malicious user who possesses minimal information about the application, typically limited to the URL or the application's login interface.

Incorporating Established Frameworks

The  Open Web Application Security Project (OWASP) has curated a list of the 10 most critical vulnerabilities frequently observed in Large Language Model (LLM) applications. This compilation underscores their potential impact, ease of exploitation, and prevalence in real-world applications. The objective of this list is to raise awareness surrounding these vulnerabilities, propose effective remediation strategies, and ultimately enhance the overall security stance of LLM applications.

Additionally, MITRE ATLAS (Adversarial Threat Landscape for Artificial-Intelligence Systems) serves as a comprehensive and globally accessible repository, providing real-world insights into adversary tactics and techniques observed through actual attacks and realistic demonstrations by AI red teams and security groups. Modeled after the MITRE ATT&CK framework, ATLAS complements ATT&CK by offering tactics, techniques, and procedures (TTPs) specifically tailored to the nuances of AI-based threats.

**💡Pro Tip: Learn how Lakera’s solutions align with the MITRE ATLAS framework.**

Adapting established cybersecurity principles for LLMs involves a nuanced approach to address unique challenges. Tailoring OWASP's guidelines requires a focus on data protection, access controls, and secure coding for the intricate nature of language models. Incorporating ATLAS's continuous monitoring is crucial for real-time surveillance of evolving LLM dynamics. Ethical considerations, including delineating content boundaries and safeguarding against biases and misinformation, play a pivotal role.

While LLMs present unique security challenges, integrating tried and tested cybersecurity practices provides a strong foundation. However, deploying these practices requires careful strategy and consideration of best practices which we will discuss next.

Deployment Strategies and Best Practices

In this section we will discuss the effective and secure LLM deployment strategies and highlight the best practices to mitigate adversarial risks.

Strategic Deployment Considerations

The foundation for the strategic deployment of LLMs lies in establishing a robust system architecture that is specific to LLM security. This necessitates the creation of secure server environments and the implementation of reliable data storage solutions, forming the backbone of a resilient security infrastructure.

An example of such strategic deployment consideration is data decentralization, as shown in this paper, where the authors motivate the problem from a medical/clinical point of view. Although LLMs, such as GPT-4, have shown potential in improving chatbot-based systems in healthcare, their adoption in clinical practice faces challenges, including reliability, the need for clinical trials, and patient data privacy concerns.

The authors provide a general architecture (shown above) in which they identify the key components for building such a decentralized system concerning data protection legislation, independently of the specific technologies adopted and the specific health conditions it will be applied to. The system enables the acquisition, storing, and analysis of users’ data, but also mechanisms for user empowerment and engagement on top of profiling evaluation.

Another key emphasis of LLM security is placed on scalability, acknowledging the inherent demands of such language models in handling vast amounts of data and meeting high-performance requirements. The delicate balance between scalability and security is crucial, ensuring that the deployed solutions can seamlessly scale to accommodate the dynamic nature of LLMs without compromising the integrity of the security framework.

An example of an attempt to make LLMs scalable is the TStreamLLM framework that integrates Transactional Stream Processing (TSP) with LLM management. TSP, an emerging data stream processing paradigm, offers real-time adaptation, data consistency, fault tolerance, and fine-grained access control—qualities that make it suitable for managing LLMs under intensive concurrent stream processing scenarios. Leveraging TSP’s capabilities TStreamLLM reduces the best achievable long-run latency to a linear function of the single-user-single-run model manipulation overhead. These innovations could expand the potential of LLMs across a multitude of AI applications.

Adversarial Risk Mitigation

Adversarial risks pose a threat to LLMs, and encompass a myriad of malicious activities that seek to compromise the integrity of these advanced language systems. The different adversarial risks are as follows:

  1. Injection Attacks: Adversaries may attempt to inject malicious data into the LLM to manipulate its outputs or compromise its functionality.
  2. Model Manipulation: Manipulating the model's outputs to produce biased or harmful results, influencing the generated content to serve malicious purposes.
  3. Poisoning Attacks: Injecting tainted data into the training dataset to distort the model's learning process, leading to biased or compromised outputs.
  4. Evasion Techniques: Adversaries may employ evasion tactics to bypass security measures, exploiting vulnerabilities in the model's understanding capabilities.
  5. Data Interference: Deliberate introduction of deceptive or misleading information into the input data to manipulate the model and influence generated outputs.
  6. Privacy Breaches: Extraction of sensitive information from the model's responses, leading to privacy violations or unauthorized access to confidential data used during training.
  7. Semantic Attacks: Crafting inputs with subtle changes to manipulate the semantic meaning of the generated content, potentially leading to misinformation or miscommunication.
  8. Transfer Learning Attacks: Exploiting vulnerabilities in the model's transfer learning capabilities to transfer biases or manipulate outputs from a source domain to a target domain.
  9. Adversarial Training Set Attacks: Deliberate inclusion of adversarial examples in the model's training set to influence its behavior and compromise its generalization capabilities.
  10. Syntactic Attacks: Introducing alterations to the syntax of input data to deceive the model and generate outputs with unintended or harmful implications.
  11. False Positive/Negative Generation: Adversaries may target the model's decision-making process, influencing it to produce false positives or negatives, potentially leading to erroneous actions based on generated content.

Mitigating these adversarial risks demands a multi-faceted approach. Regular model testing stands out as a foundational strategy, involving systematic evaluations to identify vulnerabilities and fortify the model against potential exploits. Implementing anomaly detection systems further strengthens the defense, enabling the prompt identification of abnormal behaviors indicative of adversarial activities. Another critical measure is the proactive updating of models with security patches. This ensures that the deployed LLMs stay resilient against emerging threats by addressing known vulnerabilities promptly.

For example, ZeroLeak is a LLM-based patching framework for mitigating side-channel information leak in LLM-based code generation. ZeroLeak’s goal is to make use of the massive recent advances in LLMs such as OpenAI GPT, Google PaLM, and Meta LLaMA to generate patches automatically. The overview of the ZeroLeak framework is shown below.
