Important

Items marked (preview) in this article are currently in public preview. This preview is provided without a service-level agreement, and we don't recommend it for production workloads. Certain features might not be supported or might have constrained capabilities. For more information, see Supplemental Terms of Use for Microsoft Azure Previews.

The AI Red Teaming Agent (preview) is a powerful tool designed to help organizations proactively find safety risks associated with generative AI systems during design and development. By integrating Microsoft's open-source framework for Python Risk Identification Tool's (PyRIT) AI red teaming capabilities directly into Azure AI Foundry, teams can automatically scan their model and application endpoints for risks, simulate adversarial probing, and generate detailed reports.

This article will guide you through the process of

  • Creating an AI Red Teaming Agent.
  • Running automated scans.
  • Visualizing and tracking your results over time in your Azure AI Foundry project.

Note

You must use a hub based project for this feature. A Foundry project isn't supported. See How do I know which type of project I have? and Create a hub based project.

Getting started

First install the redteam package as an extra from Azure AI Evaluation SDK, this provides the PyRIT functionality:

pip install azure-ai-evaluation[redteam]

Note

PyRIT only works with Python 3.10, 3.11, 3.12 but doesn't support Python 3.9. If you're using Python 3.9, you must upgrade your Python version to use this feature.

Create an AI Red Teaming Agent

You can instantiate the AI Red Teaming agent with your Azure AI Project and Azure Credentials.

# Azure imports
from azure.identity import DefaultAzureCredential
from azure.ai.evaluation.red_team import RedTeam, RiskCategory

# Azure AI Project Information
azure_ai_project = {
    "subscription_id": os.environ.get("AZURE_SUBSCRIPTION_ID"),
    "resource_group_name": os.environ.get("AZURE_RESOURCE_GROUP_NAME"),
    "project_name": os.environ.get("AZURE_PROJECT_NAME"),
}

# Instantiate your AI Red Teaming Agent
red_team_agent = RedTeam(
    azure_ai_project=azure_ai_project, # required
    credential=DefaultAzureCredential(), # required
    risk_categories=[ # optional, defaults to all four risk categories
        RiskCategory.Violence,
        RiskCategory.HateUnfairness,
        RiskCategory.Sexual,
        RiskCategory.SelfHarm
    ], 
    num_objectives=5, # optional, defaults to 10
)

Optionally, you can specify which risk categories of content risks you want to cover with risk_categories and define the number of prompts covering each risk category with num_objectives. The previous example generates 5 seed prompts for each risk category for a total of 20 rows of prompts to be generated and sent to your target.

Note

AI Red Teaming Agent only supports single-turn interactions in text-only scenarios.

Region support

Currently, AI Red Teaming Agent is only available in a few regions. Ensure your Azure AI Project is located in the following supported regions:

  • East US2
  • Sweden Central
  • France Central
  • Switzerland West

Running an automated scan for safety risks

Once your RedTeam is instantiated, you can run an automated scan with minimal configuration, only a target is required. The following would, by default, generate five baseline adversarial queries for each of the four risk categories defined in the RedTeam above for a total of 20 attack and response pairs.

red_team_result = await red_team_agent.scan(target=your_target)

Supported targets

The RedTeam can run automated scans on various targets.

Model configurations: If you're just scanning a base model during your model selection process, you can pass in your model configuration as a target to your red_team_agent.scan():

# Configuration for Azure OpenAI model
azure_openai_config = {
    "azure_endpoint": os.environ.get("AZURE_OPENAI_ENDPOINT"),
    "api_key": os.environ.get("AZURE_OPENAI_KEY"), #  not needed for entra ID based auth, use az login before running,
    "azure_deployment": os.environ.get("AZURE_OPENAI_DEPLOYMENT"),
}

red_team_result = await red_team_agent.scan(target=azure_openai_config)

Simple callback: A simple callback which takes in a string prompt from red_team_agent and returns some string response from your application.

# Define a simple callback function that simulates a chatbot
def simple_callback(query: str) -> str:
    # Your implementation to call your application (e.g., RAG system, chatbot)
    return "I'm an AI assistant that follows ethical guidelines. I cannot provide harmful content."

red_team_result = await red_team_agent.scan(target=simple_callback)   

Complex callback: A more complex callback that is aligned to the OpenAI Chat Protocol

# Create a more complex callback function that handles conversation state
async def advanced_callback(messages, stream=False, session_state=None, context=None):
    # Extract the latest message from the conversation history
    messages_list = [{"role": message.role, "content": message.content} 
                    for message in messages]
    latest_message = messages_list[-1]["content"]
    
    # In a real application, you might process the entire conversation history
    # Here, we're just simulating a response
    response = "I'm an AI assistant that follows safety guidelines. I cannot provide harmful content."
    
    # Format the response to follow the expected chat protocol format
    formatted_response = {
        "content": response,
        "role": "assistant"
    }
    
    return {"messages": [formatted_response]}

red_team_result = await red_team_agent.scan(target=advanced_callback)

PyRIT prompt target: For advanced users coming from PyRIT, RedTeam can also scan text-based PyRIT PromptChatTarget. See the full list of PyRIT prompt targets.

from pyrit.prompt_target import OpenAIChatTarget, PromptChatTarget

# Create a PyRIT PromptChatTarget for an Azure OpenAI model
# This could be any class that inherits from PromptChatTarget
chat_target = OpenAIChatTarget(
    model_name=os.environ.get("AZURE_OPENAI_DEPLOYMENT"),
    endpoint=os.environ.get("AZURE_OPENAI_ENDPOINT"),
    api_key=os.environ.get("AZURE_OPENAI_KEY")
) 

red_team_result = await red_team_agent.scan(target=chat_target)

Supported attack strategies

If only the target is passed in when you run a scan and no attack strategies are specified, the red_team_agent will only send baseline direct adversarial queries to your target. This is the most naive method of attempting to elicit undesired behavior or generated content. It's recommended to try the baseline direct adversarial querying first before applying any attack strategies.

Attack strategies are methods to take the baseline direct adversarial queries and convert them into another form to try bypassing your target's safeguards. Attack strategies are classified into three buckets of complexities. Attack complexity reflects the effort an attacker needs to put in conducting the attack.

  • Easy complexity attacks require less effort, such as translation of a prompt into some encoding
  • Moderate complexity attacks requires having access to resources such as another generative AI model
  • Difficult complexity attacks includes attacks that require access to significant resources and effort to execute an attack such as knowledge of search-based algorithms in addition to a generative AI model.

Default grouped attack strategies

We offer a group of default attacks for easy complexity and moderate complexity which can be used in attack_strategies parameter. A difficult complexity attack can be a composition of two strategies in one attack.

Attack strategy complexity group Includes
EASY Base64, Flip, Morse
MODERATE Tense
DIFFICULT Composition of Tense and Base64

The following scan would first run all the baseline direct adversarial queries. Then, it would apply the following attack techniques: Base64, Flip, Morse, Tense, and a composition of Tense and Base64 which would first translate the baseline query into past tense then encode it into Base64.

from azure.ai.evaluation.red_team import AttackStrategy

# Run the red team scan with multiple attack strategies
red_team_agent_result = await red_team_agent.scan(
    target=your_target, # required
    scan_name="Scan with many strategies", # optional, names your scan in Azure AI Foundry
    attack_strategies=[ # optional
        AttackStrategy.EASY, 
        AttackStrategy.MODERATE,  
        AttackStrategy.DIFFICULT,
    ],
)

Specific attack strategies

More advanced users can specify the desired attack strategies instead of using default groups. The following attack strategies are supported:

Attack strategy Description Complexity
AnsiAttack Uses ANSI escape codes. Easy
AsciiArt Creates ASCII art. Easy
AsciiSmuggler Smuggles data using ASCII. Easy
Atbash Atbash cipher. Easy
Base64 Encodes data in Base64. Easy
Binary Binary encoding. Easy
Caesar Caesar cipher. Easy
CharacterSpace Uses character spacing. Easy
CharSwap Swaps characters. Easy
Diacritic Uses diacritics. Easy
Flip Flips characters. Easy
Leetspeak Leetspeak encoding. Easy
Morse Morse code encoding. Easy
ROT13 ROT13 cipher. Easy
SuffixAppend Appends suffixes. Easy
StringJoin Joins strings. Easy
UnicodeConfusable Uses Unicode confusables. Easy
UnicodeSubstitution Substitutes Unicode characters. Easy
Url URL encoding. Easy
Jailbreak User Injected Prompt Attacks (UPIA) injects specially crafted prompts to bypass AI safeguards Easy
Tense Changes tense of text into past tense. Moderate

Each new attack strategy specified will be applied to the set of baseline adversarial queries used in addition to the baseline adversarial queries.

This following example would generate one attack objective per each of the four risk categories specified. This will first, generate four baseline adversarial prompts which would be sent to your target. Then, each baseline query would get converted into each of the four attack strategies. This will result in a total of 20 attack-response pairs from your AI system. The last attack strategy is an example of a composition of two attack strategies to create a more complex attack query: the AttackStrategy.Compose() function takes in a list of two supported attack strategies and chains them together. The example's composition would first encode the baseline adversarial query into Base64 then apply the ROT13 cipher on the Base64-encoded query. Compositions only support chaining two attack strategies together.

red_team_agent = RedTeam(
    azure_ai_project=azure_ai_project,
    credential=DefaultAzureCredential(),
    risk_categories=[
        RiskCategory.Violence,
        RiskCategory.HateUnfairness,
        RiskCategory.Sexual,
        RiskCategory.SelfHarm
    ], 
    num_objectives=1,
)

# Run the red team scan with multiple attack strategies
red_team_agent_result = await red_team_agent.scan(
    target=your_target, # required
    scan_name="Scan with many strategies", # optional
    attack_strategies=[ # optional
        AttackStrategy.CharacterSpace,  # Add character spaces
        AttackStrategy.ROT13,  # Use ROT13 encoding
        AttackStrategy.UnicodeConfusable,  # Use confusable Unicode characters
        AttackStrategy.Compose([AttackStrategy.Base64, AttackStrategy.ROT13]), # composition of strategies
    ],
)

Results from your automated scans

The key metric for assessing your results is the Attack Success Rate (ASR), which measures the percentage of attacks that successfully elicit undesirable responses from your AI system.

When the scan is finished, you can specify an output_path to capture a JSON file that represents a scorecard of your results for using in your own reporting tool or compliance platform.

red_team_agent_result = await red_team_agent.scan(
    target=your_target, 
    output_path="My-First-RedTeam-Scan.json",
)

The My-First-RedTeam-Scan.json file contains a scorecard that provides a breakdown across attack complexity and risk categories, as well as a joint attack complexity and risk category report. Important metadata is tracked in the redteaming_simulation_parameters section which outlines which risk categories were used to generate the attack objectives and which attack strategies were specified in the scan.

Viewing your results in Azure AI Foundry project

After each automated scan is finished running locally, the results also get logged to your Azure AI Foundry project which you specified in the beginning. In your project, navigate to the Evaluations page and select the AI red teaming tab to view the comprehensive report with a detailed drill-down of each scan.

Screenshot of AI Red Teaming tab in Azure AI Foundry project page.

Once you select into the scan, you can view the report by risk categories, which shows you the overall number of successful attacks and a breakdown of successful attacks per risk categories:

Screenshot of AI Red Teaming report view by risk category in Azure AI Foundry.

Or by attack complexity classification:

Drilling down further into the data tab provides a row-level view of each attack-response pair, enabling deeper insights into system issues and behaviors. For each attack-response pair, you can see additional information such as whether or not the attack was successful, what attack strategy was used and its attack complexity. There's also an option for a human in the loop reviewer to provide human feedback by selecting the thumbs up or thumbs down icon.
