Red Teaming: Cyber vs AI - Understanding the Differences & Best Practices

In today's rapidly evolving technological landscape, the concept of red teaming has become increasingly vital for organizations seeking to fortify their defenses against both cyber and artificial intelligence threats. This comprehensive guide dives deep into the nuances of red teaming in both domains, exploring the limitations of traditional cyber approaches when applied to AI and highlighting the crucial best practices that enhance AI security and resilience. We'll delve into responsible vulnerability disclosure and examine the policy landscape shaping the future of AI red teaming.

Red Teaming in the Cyber World: Emulating the Enemy

In the cybersecurity realm, red Teaming is the practice of simulating real-world threat actors to assess an organization's security posture. This involves a dedicated team (the 'red team') employing tactics, techniques, and procedures (TTPs) mirroring those of known adversaries to identify vulnerabilities and weaknesses in systems, applications, and infrastructure.

This proactive approach helps organizations understand their attack surface, identify blind spots, and improve their overall security readiness.

Red teaming activities encompass a wide range of simulated attacks, including:

• Exploiting vulnerabilities in web applications and mobile apps
• Conducting social engineering attacks to compromise employee accounts
• Evaluating the security of network infrastructure and cloud environments
• Assessing the effectiveness of incident response plans and security monitoring capabilities

The ultimate goal is to provide a realistic assessment of an organization's ability to withstand a determined cyberattack.

The Shift to AI Red Teaming: A New Frontier

While the principles of red teaming remain consistent, applying them to the realm of artificial intelligence requires a fundamental shift in perspective.

AI systems, particularly Generative AI models, Present a unique set of challenges that traditional cybersecurity approaches struggle to address.

The risk surface of generative AI is far broader than that of traditional software systems. Generative AI models can produce diverse and unpredictable outputs, making it difficult to anticipate and mitigate potential harms. These outputs can include:

• Misinformation and disinformation
• Biased or discriminatory content
• Malicious code or exploits
• Privacy violations

Furthermore, AI systems are often complex and opaque, making it difficult to understand their decision-making processes and identify potential vulnerabilities. This necessitates a new approach to red teaming that focuses on:

• Evaluating the safety and ethical implications of AI outputs
• Identifying and mitigating biases in training data and algorithms
• Assessing the resilience of AI systems to adversarial attacks
• Developing responsible disclosure practices for AI vulnerabilities

Threat Modeling for AI: Identifying Potential Adversaries and Attack Vectors

Threat modeling is a crucial step in AI red teaming, involving identifying potential adversaries and their motivations, as well as the attack vectors they might employ. Unlike traditional cybersecurity threats, AI systems face a unique set of attackers, including:

• Nation-state actors: Seeking to leverage AI for espionage, sabotage, or influence operations.
• Criminal organizations: Exploiting AI for fraud, extortion, or identity theft.
• Disgruntled employees: Sabotaging AI systems or stealing sensitive data.
• Researchers and hobbyists: Probing AI systems for vulnerabilities or ethical shortcomings.

The attack vectors against AI systems can also be quite diverse, encompassing:

• Data poisoning: Injecting malicious data into training datasets to corrupt the AI model.
• Adversarial attacks: Crafting inputs designed to mislead the AI model into producing incorrect or harmful outputs.
• Model theft: Stealing or reverse-engineering AI models to gain a competitive advantage or create malicious applications.
• Prompt injection: Manipulating the prompts provided to generative AI models to Elicit unintended or harmful responses.

Understanding these potential adversaries and attack vectors is essential for designing effective red teaming exercises.

Navigating Ethical and Legal Boundaries in AI Red Teaming

AI red teaming exercises must be conducted within ethical and legal boundaries, ensuring that the testing activities do not cause harm or violate any applicable laws or regulations. This requires careful consideration of:

• Privacy: Protecting sensitive data used in AI training and testing.
• Bias: Avoiding the use of biased data or algorithms that could perpetuate discrimination.
• Transparency: Clearly communicating the purpose and scope of red teaming exercises to stakeholders.
• Accountability: Establishing clear lines of responsibility for any harms caused by red teaming activities.

Organizations should develop a comprehensive ethics framework for AI red teaming, outlining the principles and guidelines that govern all testing activities. This framework should be regularly reviewed and updated to reflect evolving ethical and legal standards.

Leveraging Lessons Learned from Cyber Red Teaming

While AI red teaming requires a unique approach, there are valuable lessons to be learned from the established field of cyber red teaming.

These lessons include:

• Utilizing mixed talent: Assembling a diverse team with expertise in AI, cybersecurity, ethics, and Relevant domain knowledge.
• Expanding beyond just 'red-teaming': Generating actionable recommendations and solutions based on exercise findings.
• Keeping the list of informed small: Limiting awareness of the exercise to prevent stakeholders from skewing results.
• Responsible disclosure practices: Establishing clear guidelines for disclosing vulnerabilities to vendors and the public.

Tailoring Red Teaming Methodologies for Generative AI

To effectively evaluate the unique risks posed by generative AI, organizations should consider adapting existing red teaming methodologies or developing new ones tailored to the specific characteristics of these models. Key considerations include:

• Prompt Engineering and Fuzzing: Experimenting with diverse and adversarial prompts to uncover vulnerabilities.
• Output Analysis and Validation: Employing automated and human review processes to assess the safety, quality, and ethical implications of AI outputs.
• Adversarial Retraining: Developing techniques to retrain AI models to be more resilient to adversarial attacks.
• Human-in-the-Loop Evaluation: Incorporating human feedback and judgment into the red teaming process to identify subtle biases and ethical concerns.

Disclosure and Remediation Strategies: Addressing AI Vulnerabilities Responsibly

When vulnerabilities are discovered in AI systems, it is crucial to address them responsibly and transparently.

This involves:

• Establishing clear channels for reporting vulnerabilities to vendors.
• Working collaboratively with vendors to develop and deploy patches.
• Providing Timely and accurate information to users about known vulnerabilities and mitigation steps.
• Considering the potential impact of public disclosure on the broader AI ecosystem.

Organizations should also consider participating in industry-wide initiatives to promote responsible vulnerability disclosure and remediation in the AI domain, such as the work being done by CERT and CISA. Their websites are: sei.cmu.edu/about/divisions/cert/ and cisa.gov
