Red teaming large language models: Enterprise security in the AI era

In the security world, we’re always trying to stay ahead of attackers. And with AI becoming increasingly prevalent across the enterprise, we’re facing new challenges — but many fundamental security principles still apply.

Red teaming AI models is about understanding how LLMs work to identify new types of vulnerabilities — looking at everything from prompt injection, to toxic output generation, to misuse of AI systems. It’s not just about the model itself, but also how it interacts with its ecosystem.

Today, I’m breaking down why red teaming is crucial for AI security in the enterprise and offering up some best practices and practical strategies in the face of growing AI security challenges.

While AI brings new complexities to the table, much of AI security involves applying evergreen security concepts in a slightly different format. At its core, it’s about understanding what LLMs are capable of and staying one step ahead.

Understanding AI Red Teaming

AI red teaming simulates potential attacks to exploit or manipulate AI systems, identifying vulnerabilities before real-world exploitation. With AI models, we look at prompt injections, confused deputy attacks, ways to generate harmful content and attempts to bypass built-in safeguards.

That said, the threat landscape in AI is evolving rapidly. We’re seeing new types of attacks emerge as AI becomes more prevalent and powerful. Things like model poisoning, data extraction, and adversarial examples are becoming more sophisticated. It’s a constant game of cat and mouse.

For instance, researchers have demonstrated prompt injection attacks against OpenAI’s gpt-4o-mini and Google’s Gemini, tricking the models with malicious instructions. And with model inversion attacks on facial recognition systems, attackers were able to reconstruct private training data from the model itself.

That’s why having an understanding of both how AI models work as well as traditional offensive security methodologies is key — not only to find net new vulnerabilities but to also make sure fundamental security practices are being followed.

In fact, much of AI red teaming is informed by fundamental security practices. We’re applying the same mindset — trying to break things, find weak points and then figure out how to fix them. The difference is in the specific techniques and the unique aspects of AI systems.

The key is to be thorough and creative. We’re not just running through a checklist — we’re actively trying to outsmart the system, find blind spots, and exploit any weaknesses. It’s about thinking outside the box and anticipating what a real attacker might try.

The Importance of AI Red Teaming for Enterprise Security

AI red teaming is particularly critical in an enterprise environment. We’re not waiting for problems to pop up — we’re proactively seeking out vulnerabilities before they can be exploited.

That’s what sets red teaming apart. Its proactive nature helps us identify issues unique to AI systems that aren’t always obvious from standard security audits. We’re looking at model bias, unexpected outputs, or ways the AI might be manipulated into flawed decision-making or producing harmful, toxic content. These vulnerabilities could have serious consequences for enterprise customers if not caught early.

When a vulnerability is found, it’s crucial to develop long-term solutions. It’s not just about patching the system and moving on. We should work through how to resolve the issue for good. The question is always, “How do we make sure this doesn’t happen in the future?”

The solutions vary. Sometimes it’s tweaking the model or feeding it additional training data to cover edge cases. Other times, we might need new guardrails — checks or filters that prevent the model from going down problematic paths.

This iterative, back-and-forth process is crucial for ensuring responsible AI deployment in the enterprise. Systematically testing, improving, and securing these systems makes sure they’re ready for the real world.

Challenges in Standardizing AI Red Teaming

Standardizing AI red teaming is a complex challenge due to the inconsistency in how organizations approach it. This inconsistency often stems from the varied backgrounds of AI security professionals. Many come from traditional offensive security roles, where diverse methods and perspectives can both enrich and complicate red teaming practices. While this diversity of approaches also affects traditional cybersecurity red teaming to some extent, it’s particularly pronounced in the emerging field of AI security.

For instance, a network penetration tester may approach AI security differently than someone specializing in social engineering. This variation in approaches leads to different red teaming strategies and makes it difficult to compare results across organizations or establish industry-wide best practices. What one team views as a critical vulnerability might be deemed minor by another, creating confusion for enterprises evaluating AI security. While this also applies to non AI technologies, the issue is exasperated by not having a standardized method for comparison.

More powerful AI systems mean more connected systems, which in turn means more potential points of failure or attack.

The industry needs a common framework for AI red teaming to facilitate comparison, set benchmarks, and establish minimum security requirements. Organizations like OWASP are developing guidelines, but comprehensive, widely-accepted standards are still lacking.

Another challenge is balancing standardization with model-specific testing. Different AI models have varying risk profiles and vulnerabilities. A one-size-fits-all approach may overlook critical issues specific to certain models or use cases. For example, security needs for a customer service chatbot differ significantly from those for an AI used in financial trading.

To address these challenges, increased collaboration between AI developers, security professionals, and regulatory bodies is essential. While it’s a complex task, it is crucial for ensuring the safe and responsible deployment of AI systems in enterprise environments.

Key Strategies and Best Practices in Enterprise AI Red Teaming

Effective AI red teaming involves proactive strategies to uncover vulnerabilities and ensure system robustness. Leveraging automation is crucial for effective red teaming. Automated testing allows for the efficient exploration of an AI system’s behavior across thousands or even millions of scenarios. This approach helps identify issues that might not be apparent from manual testing alone.

Beyond automation, organizations must focus on several critical areas to enhance AI security:

Preventing Toxic Output Generation

Safeguarding against the generation of harmful, biased, or inappropriate content is paramount. Ensure the AI is built to discourage the creation of harmful, biased, or inappropriate content by analyzing its responses to large datasets of potentially problematic prompts. This approach helps in identifying concerning patterns that could lead to significant issues.

There are several ways to consider when trying to prevent toxic output generation:

• Use specialized models, for example PurpleLlama (developed by Meta), which are trained to detect harmful content in both responses to users and input provided by users
• Implement hallucination and prompt injection protections. These measures help prevent the AI from generating false or manipulated content, indirectly reducing the risk of harmful outputs

Protecting System Integrity

Beyond outputs, consider how the AI interacts with its integrations. Safeguard against manipulation of decision-making processes, information extraction, or misuse as an attack vector. Applying the principle of least privilege is another effective strategy; restrict the AI to only the permissions necessary for its function to limit potential damage if compromised.

A key consideration in this area is protecting against confused deputy attacks. For example, many AI systems, especially in an enterprise environment, have access to both public and confidential data. If not properly designed, an attacker could potentially trick the AI into revealing private information by crafting clever prompts. To prevent this, you can implement access controls at the system level, not within the AI model itself.

In practice, this means:

1. Separating authentication and authorization from the AI model.
2. Implementing robust access control lists (ACLs) at the application or database level.
3. Ensuring the AI model doesn’t have direct access to sensitive data sources.

With these strategies, you create a clear separation between the AI’s decision-making capabilities and the system’s access control mechanisms, reducing the risk of unauthorized data access or system manipulation.

Continuously Learning and Adapting

Keep red teaming practices up-to-date with the evolving AI landscape. Regularly update test suites and develop new tests as new threats emerge. Collaboration between red teams, model developers, and stakeholders is crucial for understanding issues and developing effective mitigations.

Additionally, it’s key to maintain thorough documentation of red teaming activities to help track progress, provide insights for future developments, and support regulatory compliance. The ultimate goal is to make AI systems more robust and secure, ensuring safe and reliable deployments.

Remember, the goal of red teaming isn’t just to find problems – it’s to make your AI systems more robust and secure. By integrating these practices into your development process, you can help ensure that your AI deployments are as safe and reliable as possible.

The Future of AI Security and Red Teaming

No business wants to become less efficient over time, but that’s precisely the risk we face if we don’t get ahead of these security challenges. More powerful AI systems mean more connected systems, which in turn means more potential points of failure or attack. The problems we face today will only compound if left unaddressed.

The importance of red teaming in this context cannot be overstated. It’s our front-line defense against unforeseen vulnerabilities, our reality check against overconfidence, and our guide for continuous improvement. Red teaming isn’t just about finding flaws — it’s about fostering a culture of security-mindedness that permeates every aspect of AI development and deployment.

For enterprises, the call to action is clear: prioritize AI security measures now. Don’t wait for a high-profile incident or regulatory crackdown. Integrate robust security practices, including comprehensive red teaming, into your AI development pipelines from the ground up. Invest in the tools, talent and processes needed to stay ahead of emerging threats.
