Remove policy from application

​

Event Information

• The “Remove policy from application” event in Azure Active Directory refers to the action of removing a policy that was previously associated with an application.
• This event typically occurs when an administrator or a user with the necessary permissions decides to remove a policy that was previously configured for an application in Azure Active Directory.
• Removing a policy from an application can have various implications, such as changing the access control rules, authentication requirements, or other security settings associated with the application. It is important to carefully consider the impact of removing a policy before taking this action.

​

Examples

1. Unauthorized access: Removing a policy from an application in Azure Active Directory can potentially lead to unauthorized access to sensitive resources. Without the policy in place, there may be no restrictions on who can access the application, increasing the risk of unauthorized users gaining access to sensitive data or functionalities.
2. Data breaches: Removing a policy from an application can weaken the security controls that protect sensitive data. This can increase the likelihood of data breaches, where unauthorized individuals gain access to and potentially misuse or steal sensitive information stored within the application.
3. Compliance violations: Many compliance standards require the implementation of specific security policies to protect sensitive data. Removing a policy from an application can result in non-compliance with these standards, potentially leading to legal and financial consequences for 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.
   • Define the conditions under which the policy should be applied, such as user/group, location, device state, etc.
   • Configure the access controls, such as requiring MFA, blocking access, or granting access only from trusted locations.
   • Save the policy and ensure it is enabled.
3. Monitor and Respond to Security Alerts:
   • In the Azure portal, navigate to the Azure Active Directory service.
   • Select “Security” from the left-hand menu.
   • Under “Manage,” click on “Security alerts” to access the security alerts dashboard.
   • Review the alerts and investigate any suspicious or potentially malicious activities.
   • Take appropriate actions based on the severity of the alert, such as blocking a user, resetting passwords, or escalating to the incident response team.
   • Regularly monitor the security alerts and adjust the policies and configurations as needed to enhance security.

​

Using CLI

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

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
   
   credential = DefaultAzureCredential()
   graph_client = GraphRbacManagementClient(credential, "<your-tenant-id>")
   
   user_object_id = "<user-object-id>"
   new_password = "<new-password>"
   
   graph_client.users.update_password(user_object_id, new_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
   
   credential = DefaultAzureCredential()
   graph_client = GraphRbacManagementClient(credential, "<your-tenant-id>")
   
   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. Create a New 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 create a new user.
   • Here’s an example script:

   from azure.mgmt.graphrbac.models import UserCreateParameters
   
   credential = DefaultAzureCredential()
   graph_client = GraphRbacManagementClient(credential, "<your-tenant-id>")
   
   new_user = UserCreateParameters(
       account_enabled=True,
       display_name="<user-display-name>",
       mail_nickname="<user-mail-nickname>",
       user_principal_name="<user-principal-name>",
       password_profile={
           "password": "<user-password>",
           "force_change_password_next_login": False
       }
   )
   
   graph_client.users.create(new_user)
