Testing Generative AI: Benchmarking and red teaming

Benchmarking and red teaming are two important components in testing generative AI systems. Benchmarking establishes standard performance metrics, allowing for consistently evaluating the AI's capabilities and ensuring it meets predefined quality and accuracy standards. On the other hand, red teaming simulates adversarial attacks to uncover vulnerabilities, helping to identify and avoid potential security threats, thereby ensuring the AI system is robust and safe for deployment. Let's explore them further.

1. Test generative AI system through benchmarking

First, you need to set goals for what the AI should be able to do. Before making the AI, decide on tasks or questions it should be able to handle. You can achieve these goals by working with testers, product managers, and AI experts to ensure that AI can handle real-world situations.
Here are some steps to take when benchmarking generative AI system:

  • Defining benchmarks: Begin by defining a set of benchmarks aligned with the system's intended capabilities. This step should be established before development to guide the design process.
  • Establishing metrics: Determine how to quantify the AI's performance. It is essential to identify a set of quality metrics measured in percentages rather than just pass/fail. For example, if you have an AI-powered testing tool, assess its effectiveness in generating requirements-based tests.
  • Diversity of data: Ensure the benchmarking data is diverse, covering various regions, demographic groups, or products as needed. This diversity is vital to assess the system's ability to perform well across different contexts.
  • The primary role of the tester: The tester's job is to define the benchmarks and ensure quality metrics are in place. This involves aligning product management and AI engineers on these quality standards.
  • Exploratory testing: In addition to automated benchmarking tests, exploratory testing is also used to identify unexpected behaviors or weaknesses in the AI system.
  • Regular monitoring: Monitor the system for errors, biases, or hallucinations in the outputs.

2. Red teaming for generative AI testing

Red teaming is a security and testing practice used for generative AI systems. This approach involves a team of experts trying to identify and exploit vulnerabilities in the AI system to reveal potential risks and harms. The primary goal of red teaming in generative AI testing is to ensure the system is robust against attacks and data leaks, safeguarding against financial losses, reputational damage, and other severe consequences.

In red teaming, there are usually two main personas with different roles:

  • The benign persona uses the AI system as intended, exploring potential harms without malicious intent. Under normal usage, this approach tests whether the AI could inadvertently cause harm or operate outside its intended scope. Harms discovered through benign interactions are often more concerning, as they can occur during regular use.
  • The adversarial persona, on the other hand, employs any means necessary to force the AI to misbehave, including prompt hacking, token overflowing, and other security-focused tactics. Although adversarial testing often identifies lower-impact harms due to the extreme measures required, it is essential for uncovering vulnerabilities like data leaks, where an attacker might exploit the system.

How do we set up and plan red teaming?

Here are the steps you should take to set up and plan red teaming:

  • Create a working charter: Develop a detailed charter outlining expected harms and leave room for discovering additional issues during the process.
  • Define team roles: Assign and rotate specific roles such as benign, adversarial, and advisory to utilize various perspectives. Provide comprehensive guides for effective testing strategies.
  • Thorough documentation: Record every identified harm, including the entire sequence and context, to ensure a complete understanding of the vulnerabilities.
  • Focus the scope: Concentrate on specific harms during each session to ensure thorough testing. Avoid overly broad objectives to maintain effectiveness.
  • Set time limits: Establish clear time constraints for each session and the overall number of sessions to keep the team focused and ensure timely completion.
  • Iterative testing: Conduct testing in multiple rounds, regrouping after each to share insights and refine the approach for subsequent sessions.

Methods for testing generative AI and detecting potential harms

Let's explore additional strategies you can implement to test your generative AI.

1. Extracting sensitive data

Remember that generative AI systems produce a huge amount of data, which can sometimes be overwhelming. The red team's role is to find ways to extract sensitive data, such as internal information or personally identifiable information (PII), that may have been incorporated into the AI model. A key aspect is determining whether the AI has been trained on internal or customer-sensitive data. If so, the red team must be skilled at extracting this data from generative AI systems, like obtaining information that should not be accessible to users or the public. For example:

  • Extracting meta-prompts and training data: The AI may unintentionally expose the instructions and examples it was trained on, providing insights into its operational mechanisms and programming, which are typically kept confidential.
  • Accessing information from unintended sources: This could happen if the AI, through some manipulation, starts to pull information from databases or sources it was not intended to access. For example, this occurs if an AI designed to provide customer support starts accessing and revealing financial records.
  • Extracting PII: In this scenario, the AI is manipulated into divulging personal user information, like addresses or phone numbers, or even more sensitive data, like passwords or security keys.

2. Prompt overflow

"Prompt overflow," a strategy used by red teams, involves intentionally inundating the system with substantial input to disrupt its core function. This common tactic can potentially repurpose the AI for unintended outcomes, ranging from exposing sensitive data to generating irrelevant or harmful content.

3. System hijacking

The most critical aspect of system hijacking is ensuring the AI system cannot be manipulated into performing unauthorized actions or repurposing its functionalities. This includes:

  • Misuse of tools: Hijacking involves manipulating the AI into using internet access or external tools for unintended purposes, such as downloading large files or accessing prohibited sites.
  • Repurposing instructions: Hijacking can also entail altering the AI's intended function, like transforming an educational AI into a tool for promoting specific products or ideologies.
  • Remote code execution: Hijacking may involve using AI to execute malicious code on other systems, potentially initiating unauthorized actions or downloads.

4. Unauthorized legal commitments

This method's primary concern is evaluating the AI's potential to make unauthorized legal commitments or provide false information about company policies, discounts, or services. Ensuring the AI does not misrepresent the company, potentially causing legal issues or reputational damage is crucial.

6. Inappropriate tone

The key focus here is ensuring the AI maintains an appropriate and respectful tone in all interactions. The goal is to evaluate the AI's responses to ensure it does not exhibit aggressive, disrespectful, or condescending behavior toward users.

7. Malware defense

The critical aspect of malware defense is ensuring the AI system cannot be exploited to execute malicious actions, such as downloading viruses or interacting with external systems in harmful ways. Simulating attacks helps evaluate the AI’s safeguards against cyber threats.

8. External access control

The most important aspect of this strategy is assessing the AI’s access to external tools and APIs to prevent unauthorized data manipulation or deletion. Testers must simulate scenarios where the AI might misuse its permissions and evaluate the potential impact of these actions, ensuring the system’s security and integrity.
