Red teaming entails active assessment of AI models to prevent malicious implications, such as sensitive information disclosure or material production, with a view to toxicity, bias, or incorrect facts.
Introduction to Red Teaming
Red teaming has been around for decades, long before today’s sophisticated generative AI models even existed. It first appeared when the U.S. military’s secret strategic exercises took place among military organizations. It then evolved into an art of learning how adversaries would think strategically. Afterward, the IT industry adopted red teaming to test computer networks, systems, and software to look for faults that can be exploited by a bad actor.
Red teaming has found a new ground in its recent past: stress-testing generative AI across safety, security, and social biases. The risks in the industrial context of generative AI differ from those of conventional software models, and potential hazards range from hate speech, p**********, false facts, copyrighted material, or even the disclosure of private data like phone numbers and social security numbers. Red teaming tries to artificially provoke the generative AI to generate outputs contrary to the developers’ intention and uncover any biases or vulnerabilities that may not have been known yet.
Once vulnerabilities are exposed through red teaming, the necessary steps are to develop new training data or enhance the model’s safety and security features. Redditors had been jailed-breaking early ChatGPT through strategies of pressuring it into providing advice on activities such as bomb-making or tax evasion by personating another persona in the chat. Other exploit approaches include using languages not humanly perceptible or mixing gibberish text with commands.
“Generative AI is actually very difficult to test. Who specializes in adversarial AI-testing. “It’s not like a classifier, where you know the outcomes. With generative AI, the generation space is very large, and that requires a lot more interactive testing.” – Pin-Yu Chen, Principal Research Scientist at IBM
Improve AI Safety and Security with Red Teaming
- Alignment Phase in Fine-Tuning Process: Crucial for safe, secure, and trustworthy AI. Human values and objectives transfer to Large Language Models (LLMs) using examples of target tasks (questions and answers). Imitation of rewards to train a reward model towards desirable preferences.
- AI Red Teaming: Deploys adversarial attacks by designing prompts that circumvent safety controls on the model. Mostly comes from human-designed jailbreak prompts, which are increasingly being red-teamed through LLMs that produce thousands of prompts every day.
- Red Team LLMs: Act as baiters to provoke negative responses from targeted models, especially in redesigning AI systems. Detect vulnerabilities for redesigning.
- IBM Adversarial and Open-Source Datasets: Develops datasets like AttaQ and SocialStigmaQA, which are useful in advancing the Granite family of models, such as Watsonx. It helps in advancing Aurora, a multilingual model.
- Continued Emphasis on AI Security: Eitan Farchi from IBM put a lot of thought into the fact that there is a continued need to keep up with this cat-and-mouse game.
- The New “Curiosity” Algorithm: Eaton Farchi of IBM introduced an algorithm that gives priority to creativity for generating new ideas. IBM and MIT researchers address newer threats from generative AI models. Research on vulnerabilities in safety alignment processes comes with recent findings, even of open models like OpenAI’s GPT-3.5 Turbo.
- Efforts to Protect AI Systems: Researchers forge tools to defend against real-world attacks. Tools like GradientCuff, for instance, hope to reduce LLM attacks and are instrumental in reducing success rates.
Chasing “Unknown Unknowns”: Beating Red Teaming in Generative AI
The trend of generative AI remains unclear, but the signal within the noise is growing with each passing month. It was implied with the White House co-leading a red teaming hackathon at DEFCON, signaling growing appreciation for this approach.
Likewise, the European Union recently enacted the world’s first artificial intelligence law, which prohibits certain applications of AI, such as social scoring systems, and mandates companies to evaluate and mitigate risks associated with generative AI. What happened is that various countries are putting their own regulatory framework in place. In addition, the National Institute of Standards and Technology (NIST) in the United States has recently set up the Artificial Intelligence Safety Institute, an institution of 200 AI stakeholders, including IBM.
To properly scrutinize these vast language models, it increasingly employs red teaming, which is as much automated to be effective. However, human involvement is needed. Indeed, what has to be hammered down from those models most often mimics human tendencies, proving yet again the reason why there is a persistence in human scrutiny and involvement.
Kush Varshney, an IBM Fellow whose primary area of expertise is in AI governance, heads the innovation pipeline for watsonx.governance, a suite of tools designed for auditing models deployed on IBM’s AI platform. Varshney insists that red teaming is a never-ending activity, and its performance is proportional to how many people from diverse backgrounds are involved in scrutinizing models for weaknesses. According to Varshney, one of the reasons for evolving the model is so that there is always an unknown unknown, so one requires people with diverse viewpoints and life experiences to identify potential misbehaviors in these models. The changes in the world mean that red teaming is an ever-evolving process, which may never be completed.
The Significance of Red Teaming
Eric McIntyre, VP of Product and Hacker Operations Center at IBM Security Randori, observes that red team activities identify the effectiveness of defense mechanisms. He explains: “Red team exercises show how far an attacker can penetrate a network before encountering defensive mechanisms. They make weaknesses in your defenses known and articulate them, in which cases action needs to be taken to improve these areas.
Benefits of Red Teaming
Red teaming is a strategic approach used to evaluate the effectiveness of controls, solutions, and personnel; it simulates dedicated adversaries. It provides security leaders with an assessment of an organization’s cybersecurity posture, enabling businesses to:
– Detect and assess vulnerabilities.
– Assess the effectiveness of security investments.
– Evaluate capability in threat detection and response.
– Cultivate a culture of continuous improvement.
FAQs
1. What is red teaming in the context of AI security?
Red teaming involves actively assessing AI models to preempt potential malicious implications, such as disclosing sensitive information or generating undesirable content characterized by toxicity, bias, or inaccuracies.
2. What are the specific risks associated with generative AI models?
Generative AI introduces unique risks, including the generation of hate speech, p**********, false information, copyrighted material, or the inadvertent disclosure of private data such as phone numbers and social security numbers.
3. How does red teaming mitigate these risks?
Red teaming artificially provokes generative AI models to produce outputs contrary to developers’ intentions, thereby uncovering biases or vulnerabilities that may otherwise remain unknown.
4. What steps are taken once vulnerabilities are identified through red teaming?
Upon identifying vulnerabilities, measures are implemented to either develop new training data or enhance the safety and security features of the AI model.
5. Why is red teaming particularly challenging for generative AI models?
Generative AI testing is complex due to the vast generation space, requiring extensive interactive testing compared to traditional classifiers with predictable outcomes.
6. How does red teaming contribute to improving AI safety and security?
Red teaming facilitates identifying vulnerabilities, assessing security investments, evaluating threat detection capabilities, and cultivating a culture of continuous improvement in AI systems.
