Delete group remediation

​

Event Information

• The Delete group event in Azure Active Directory refers to the action of permanently removing a group from the Azure AD tenant.
• This event signifies that a group, along with all its associated members and permissions, has been deleted and can no longer be accessed or used within the Azure AD environment.
• The Delete group event is important for auditing and compliance purposes, as it allows administrators to track and monitor the removal of groups, ensuring proper governance and security measures are in place.

​

Examples

• Unauthorized deletion of a group: If security is impacted with the Delete group operation in Azure Active Directory, it could potentially lead to unauthorized deletion of a group. This can result in the loss of important group resources, permissions, and associated user memberships, impacting the overall security posture of the organization.
• Data loss: Deleting a group in Azure Active Directory can also result in the loss of critical data associated with the group, such as group settings, group-specific attributes, and group-related metadata. This can have a significant impact on the organization’s data integrity and availability.
• Access control vulnerabilities: Deleting a group without proper authorization or oversight can introduce access control vulnerabilities. For example, if a group is deleted without removing associated user memberships or permissions, it can lead to unauthorized access to resources or data. This can compromise the confidentiality, integrity, and availability of sensitive information within the organization.

Remediation

​

Using Console

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.

​

Using CLI

1. Enable MFA for Azure AD users:
   • Use the Azure CLI command az ad user update to update the user’s MFA settings.
   • Example: az ad user update --id <user-object-id> --force-change-password-next-login true
2. Configure password policies:
   • Use the Azure CLI command az ad policy password update to update the password policy settings.
   • Example: az ad policy password update --id <policy-object-id> --password-lifetime 90 --password-history 5
3. Enable Azure AD sign-in risk policy:
   • Use the Azure CLI command az ad policy update to enable the sign-in risk policy.
   • Example: az ad policy update --id <policy-object-id> --is-enabled true

​

Using Python

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:
   Copy

   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:
   Copy

   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)
