AI Firewalls: Defending Against the New Wave of LLM Cyberthreats
Introduction
In an interview with Cyber Express, Ran S., co-founder and CTO of Nightfall AI, shared insights on the intersection of AI and cybersecurity. As AI technologies continue to revolutionize various sectors like manufacturing, BFSI, hospitality, and IT, they have naturally attracted increased scrutiny from cybercriminals. This article delves into how organizations should approach AI-related threats compared to traditional cybersecurity, the importance of data governance, and what steps can be taken to secure Large Language Models (LLMs).
The Power and Risk of LLMs
The core premise discussed revolved around the need to ensure that LLMs, such as those created by OpenAI, do not have the power to inject code into business logic. By preventing users from crafting and manipulating prompts that could be used maliciously, organizations can close potential security loopholes.
For example, a chatbot that generates database queries should have stringent authorization controls to ensure that users can only perform actions they are authorized for. This is especially critical in fields regulated by compliance standards, where sensitive data handling is a primary concern.
Different Industry Approaches
Different industries have unique requirements when adopting AI technologies. For critical infrastructure or government entities, compliance with regulations around data privacy and security is paramount. For instance, sectors like fintech and healthcare face more stringent controls due to the sensitive nature of the data they handle.
Promising Use Cases and Threats
AI is increasingly used in customer support applications, natural language processing, and speech-to-text services. However, regulating data sent to and received from these models is crucial to avoid governance and security issues. Theoretical risks like prompt injection exist, but practical, real-world incidents are the pressing concerns for many organizations.
Managing New Attack Surfaces
Securing LLMs integrated into internet-connected applications requires ensuring that the LLM itself can’t inject malicious code. Adding authorization controls and an "AI firewall" can help manage this. An AI firewall screens both inputs and outputs to and from the model, ensuring compliance and mitigating risks.
Data Governance and Compliance
When storing LLM data in the cloud, organizations should ensure they only store necessary data. Using synthetic data instead of real customer data for training models is one way to maintain privacy and security while adhering to compliance regulations.
Ethical Considerations
Ran also addressed the ethical concerns associated with AI, emphasizing the importance of data governance, synthetic data usage, and ethical training practices. He also spoke about the potential for smaller language models in specific, cost-effective applications like healthcare EMRs.
Tackling Bias and Adversarial Attacks
Mitigating bias in LLMs involves fine-tuning models with carefully curated datasets. While prompt injection attacks are theoretically possible, practical security measures like input/output sanitization can mitigate these risks.
Nightfall AI’s Role
Nightfall AI focuses on cloud data loss prevention for generative AI tools, offering a firewall to ensure that sensitive data is adequately protected. This ensures compliance and mitigates potential risks from both careless and malicious actions by end-users.
Case Study: Global Food Delivery Company
A pertinent case study involves a global food delivery company using Nightfall AI to ensure that no sensitive data is sent to third-party LLMs like those from OpenAI. This company leverages a firewall to sanitize both inputs and outputs, staying compliant with various data privacy regulations globally.
Conclusion
Ran concluded the interview with three key points for LLM mitigations: data governance, synthetic data usage, and staying abreast of research around potential AI attacks. He also discussed the practical implications of applying general compliance rules to different sectors.
