Event Information

  1. The Microsoft.AAD.register.action event in Azure for AzureIdentityManagement refers to the event that is triggered when a user or application registers a new Azure Active Directory (AAD) application.

  2. This event indicates that a new application has been registered in Azure AD, which allows it to authenticate and access Azure resources.

  3. The event provides information about the application, such as its name, client ID, and the user or application that performed the registration. It is useful for monitoring and auditing purposes, as it helps track the creation of new applications in the Azure AD tenant.

​
Examples

  • Unauthorized users may be able to register new applications or service principals in Azure Active Directory (AAD), leading to potential security breaches.
  • Malicious actors may exploit the Microsoft.AAD.register.action to gain unauthorized access to sensitive resources or data within the Azure environment.
  • The registration of unauthorized applications or service principals through this action may result in the exposure of sensitive information or the compromise of user credentials.

Remediation

​
Using Console

To remediate AzureIdentityManagement issues using the Azure console, you can follow these step-by-step instructions:

  1. Enable Multi-Factor Authentication (MFA):

    • Sign in to the Azure portal using your administrator account.
    • Navigate to Azure Active Directory.
    • Select “Users” and then “Multi-Factor Authentication.”
    • Enable MFA for all users or specific users based on your requirements.
    • Configure the MFA settings according to your organization’s security policies.

  2. Implement Role-Based Access Control (RBAC):

    • Sign in to the Azure portal using your administrator account.
    • Navigate to the resource group or specific resource you want to secure.
    • Select “Access control (IAM)” from the left-hand menu.
    • Click on “Add” and select the appropriate role for the user or group.
    • Specify the user or group you want to grant access to and save the changes.

  3. Enable Azure AD Privileged Identity Management (PIM):

    • Sign in to the Azure portal using your administrator account.
    • Navigate to Azure Active Directory.
    • Select “Privileged Identity Management” from the left-hand menu.
    • Click on “Azure resources” and then “Azure AD roles.”
    • Enable PIM for the required roles and assign eligible users.
    • Configure the activation and approval settings as per your organization’s requirements.

Note: These steps are general guidelines and may vary based on your specific Azure setup and requirements. It is recommended to refer to the official Azure documentation for detailed instructions.

​
Using CLI

To remediate Azure Identity Management issues using Azure CLI, you can follow these steps:

  1. Grant appropriate permissions to Azure AD users or groups:

    • Use the az ad group member add command to add users or groups to Azure AD groups.
    • Use the az role assignment create command to assign roles to users or groups.

  2. Enable Multi-Factor Authentication (MFA) for Azure AD users:

    • Use the az ad user update command to enable MFA for a specific user.
    • Use the az ad user update command to enforce MFA for all users.

  3. Monitor and review Azure AD sign-ins:

    • Use the az monitor activity-log list command to retrieve Azure AD sign-in logs.
    • Use the az monitor activity-log alert create command to create alerts for suspicious sign-in activities.

Please note that the specific CLI commands may vary depending on your Azure CLI version and the specific requirements of your Azure environment.

​
Using Python

To remediate Azure AzureIdentityManagement issues using Python, you can follow these steps:

  1. Grant the appropriate permissions: Use the Azure SDK for Python to programmatically assign the necessary roles and permissions to the Azure AD users or groups. You can use the azure-mgmt-authorization library to manage role assignments. Here’s an example script:
from azure.identity import DefaultAzureCredential
from azure.mgmt.authorization import AuthorizationManagementClient

# Authenticate using default credentials
credential = DefaultAzureCredential()

# Create the authorization management client
authorization_client = AuthorizationManagementClient(credential, <subscription_id>)

# Assign a role to a user or group
assignment = authorization_client.role_assignments.create(
    scope="<scope>",
    role_definition_id="<role_definition_id>",
    principal_id="<principal_id>"
)
  1. Enable Multi-Factor Authentication (MFA): Use the azure-identity library to enable MFA for Azure AD users. Here’s an example script:
from azure.identity import DefaultAzureCredential
from azure.mgmt.authorization import AuthorizationManagementClient

# Authenticate using default credentials
credential = DefaultAzureCredential()

# Create the authorization management client
authorization_client = AuthorizationManagementClient(credential, <subscription_id>)

# Enable MFA for a user
user = authorization_client.users.get("<user_id>")
user.strong_authentication_details = {
    "methods": ["OneWaySMS"],
    "phone_number": "<phone_number>"
}
authorization_client.users.update("<user_id>", user)
  1. Monitor and audit identity management activities: Use Azure Monitor to track and analyze identity management events. You can use the azure-monitor library to programmatically retrieve and analyze logs. Here’s an example script:
from azure.identity import DefaultAzureCredential
from azure.monitor.query import LogsQueryClient

# Authenticate using default credentials
credential = DefaultAzureCredential()

# Create the logs query client
logs_client = LogsQueryClient(credential)

# Query identity management logs
query = """
AzureActivity
| where OperationName == "Add user"
| project TimeGenerated, Caller, Identity, ResourceId
"""
result = logs_client.query_workspace("<workspace_id>", query)

# Process and analyze the query result
for row in result.tables[0].rows:
    time_generated = row[0]
    caller = row[1]
    identity = row[2]
    resource_id = row[3]
    # Perform further analysis or actions based on the log data

Please note that the provided scripts are just examples and may require modifications based on your specific requirements and environment.
