Event Information

  • The “Update user” event in Azure Active Directory refers to a change made to the attributes or properties of a user account within the Azure AD tenant.
  • This event can occur when an administrator or user modifies the user’s profile information, such as display name, email address, phone number, or job title.
  • The “Update user” event is important for auditing and tracking purposes, as it helps to monitor any changes made to user accounts and maintain the integrity of the Azure AD environment.

​
Examples

  1. Unauthorized access: If security is impacted with the “Update user” operation in Azure Active Directory, it could potentially allow unauthorized individuals to gain access to sensitive user information or perform malicious actions on behalf of the user. This could lead to data breaches, unauthorized account modifications, or unauthorized access to resources.

  2. Privilege escalation: If security is impacted, the “Update user” operation could potentially be exploited to escalate privileges within the Azure Active Directory. An attacker could modify user attributes or roles to gain elevated privileges, allowing them to access or modify resources that they should not have access to. This could result in unauthorized access to sensitive data or unauthorized actions within the Azure environment.

  3. Data integrity compromise: If security is impacted, the “Update user” operation could be used to modify user attributes or roles in a way that compromises the integrity of the data stored in Azure Active Directory. This could lead to data corruption, incorrect user permissions, or other issues that impact the accuracy and reliability of the data stored in the directory.

Remediation

​
Using Console

To remediate the issue for Azure Active Directory using the Azure console, you can follow these step-by-step instructions:

  1. Enable Multi-Factor Authentication (MFA):

    • Sign in to the Azure portal (portal.azure.com) using your administrator account.
    • Navigate to the Azure Active Directory service.
    • Select “Security” from the left-hand menu.
    • Under “Manage,” click on “MFA” to access the Multi-Factor Authentication settings.
    • Enable MFA for all users or specific users/groups as per your organization’s requirements.
    • Configure the MFA settings, such as the verification method (phone call, text message, mobile app), and the number of allowed methods.

  2. Implement Conditional Access Policies:

    • In the Azure portal, go to the Azure Active Directory service.
    • Select “Security” from the left-hand menu.
    • Under “Manage,” click on “Conditional Access” to access the Conditional Access policies.
    • Create a new policy or modify an existing one to enforce additional security controls based on your organization’s requirements.
    • Configure the policy settings, such as requiring MFA for specific applications or locations, blocking risky sign-ins, or granting access only from trusted devices.

  3. Enable Azure AD Identity Protection:

    • Sign in to the Azure portal using your administrator account.
    • Navigate to the Azure Active Directory service.
    • Select “Security” from the left-hand menu.
    • Under “Manage,” click on “Identity Protection” to access the Identity Protection settings.
    • Enable Azure AD Identity Protection to detect and remediate potential identity risks.
    • Configure the risk policies, such as blocking or requiring MFA for risky sign-ins, and set up alerts for suspicious activities.

Note: The above steps are general guidelines, and you should tailor them to your specific requirements and compliance standards. It is recommended to thoroughly review the Azure documentation and consult with your organization’s security team before implementing any changes.

​
Using CLI

To remediate Azure Active Directory issues using Azure CLI, you can follow these steps:

  1. Enable MFA for Azure AD users:

    • Use the az ad user update command to update the user’s MFA settings.
    • Example: az ad user update --id <user-id> --force-change-password-next-login true

  2. Configure password policies:

    • Use the az ad policy password update command to update the password policy settings.
    • Example: az ad policy password update --id <policy-id> --password-lifetime 90 --password-history-count 5

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

    • Use the az ad pim update command to enable PIM for a specific role.
    • Example: az ad pim update --id <role-id> --enabled true

Please note that the <user-id>, <policy-id>, and <role-id> placeholders should be replaced with the actual IDs or names of the users, policies, or roles you want to modify.

​
Using Python

To remediate Azure Active Directory issues using Python, you can utilize the Azure SDK for Python. Here are three examples of how you can use Python to remediate Azure Active Directory issues:

  1. Reset User Password:

    • Use the azure-identity library to authenticate with Azure Active Directory.
    • Use the azure-mgmt-graphrbac library to interact with the Azure AD Graph API.
    • Use the UserOperations class to reset the password for a specific user.
    • Here’s an example script:
    from azure.identity import DefaultAzureCredential
from azure.mgmt.graphrbac import GraphRbacManagementClient

# Authenticate with Azure Active Directory
credential = DefaultAzureCredential()
graph_client = GraphRbacManagementClient(credential, "<your-tenant-id>")

# Reset user password
user_object_id = "<user-object-id>"
password = "<new-password>"
graph_client.users.update(user_object_id, password_profile={"password": password})

  2. Enable Multi-Factor Authentication (MFA) for a User:

    • Use the azure-identity library to authenticate with Azure Active Directory.
    • Use the azure-mgmt-graphrbac library to interact with the Azure AD Graph API.
    • Use the UserOperations class to enable MFA for a specific user.
    • Here’s an example script:
    from azure.identity import DefaultAzureCredential
from azure.mgmt.graphrbac import GraphRbacManagementClient

# Authenticate with Azure Active Directory
credential = DefaultAzureCredential()
graph_client = GraphRbacManagementClient(credential, "<your-tenant-id>")

# Enable MFA for a user
user_object_id = "<user-object-id>"
user = graph_client.users.get(user_object_id)
user.additional_properties["strongAuthenticationMethods"] = [{"type": "microsoftAuthenticator"}]
graph_client.users.update(user_object_id, user)

  3. Add User to a Group:

    • Use the azure-identity library to authenticate with Azure Active Directory.
    • Use the azure-mgmt-graphrbac library to interact with the Azure AD Graph API.
    • Use the GroupOperations class to add a user to a specific group.
    • Here’s an example script:
    from azure.identity import DefaultAzureCredential
from azure.mgmt.graphrbac import GraphRbacManagementClient

# Authenticate with Azure Active Directory
credential = DefaultAzureCredential()
graph_client = GraphRbacManagementClient(credential, "<your-tenant-id>")

# Add user to a group
user_object_id = "<user-object-id>"
group_object_id = "<group-object-id>"
graph_client.groups.add_member(group_object_id, user_object_id)

Please note that you need to install the required libraries (azure-identity and azure-mgmt-graphrbac) before running these scripts.
