Microsoft.authorization.policydefinitions.write

​

Event Information

1. The Microsoft.Authorization.policyDefinitions.write event in Azure for AzureAccessManagement refers to the action of creating or updating a policy definition within the Azure Access Management service.
2. This event indicates that a user or application has made changes to the policy definition, which defines the rules and conditions for access management in Azure.
3. It is important to monitor this event as it can help track any modifications made to the policy definitions, ensuring compliance and security in the Azure environment.

Examples

1. Unauthorized modification of policy definitions: If security is impacted with Microsoft.Authorization.policyDefinitions.write in Azure for AzureAccessManagement, it could potentially allow unauthorized users to modify existing policy definitions. This could lead to the creation of policies that are not aligned with the organization’s security requirements, resulting in potential security vulnerabilities.
2. Escalation of privileges: Another security impact of Microsoft.Authorization.policyDefinitions.write in Azure for AzureAccessManagement is the potential for unauthorized users to escalate their privileges. By modifying policy definitions, attackers could grant themselves elevated access permissions, allowing them to perform actions that they are not authorized to do. This can lead to unauthorized access to sensitive resources and data.
3. Policy bypass: The ability to write policy definitions in AzureAccessManagement can also result in policy bypass. Attackers can create policies that explicitly allow certain actions or resources to be exempted from existing policies. This can be used to bypass security controls and gain unauthorized access to resources or perform actions that are otherwise restricted. It can also lead to non-compliance with regulatory requirements and industry standards.

Remediation

​

Using Console

1. Identify the specific issue: Determine the exact problem related to AzureAccessManagement that needs to be remediated. This could be related to access control, permissions, or any other specific issue.
2. Access Azure portal: Log in to the Azure portal using your credentials.
3. Navigate to Azure Access Management: Once logged in, navigate to the Azure Access Management service. You can find this service under the “Identity” section in the Azure portal.
4. Identify the affected resource: Identify the specific resource or resources that are affected by the AzureAccessManagement issue. This could be a virtual machine, storage account, or any other Azure resource.
5. Review and modify access control: Review the existing access control settings for the affected resource. Ensure that the appropriate permissions are assigned to the correct users or groups.
6. Update access control settings: If necessary, modify the access control settings to remediate the AzureAccessManagement issue. This may involve adding or removing users or groups, adjusting permissions, or making any other necessary changes.
7. Test and validate: After making the necessary changes, test and validate the access control settings to ensure that the AzureAccessManagement issue has been successfully remediated. Verify that the correct users or groups have the appropriate access to the resource.
8. Monitor and maintain: Continuously monitor the access control settings and regularly review them to ensure ongoing compliance with security and access requirements. Make any necessary adjustments or updates as needed.

Using CLI

1. Grant the necessary permissions:
   • Use the az ad app permission add command to grant the required permissions to the Azure Active Directory (AAD) application.
   • Specify the --id parameter with the AAD application ID.
   • Use the --api parameter to specify the API permissions required.
   • Use the --scope parameter to specify the scope of the permissions.
   • Repeat the command for each required permission.
2. Assign the AAD application to the role:
   • Use the az role assignment create command to assign the AAD application to the desired role.
   • Specify the --assignee parameter with the AAD application ID.
   • Use the --role parameter to specify the role to be assigned.
   • Specify the --scope parameter with the appropriate scope for the role assignment.
3. Verify the role assignment:
   • Use the az role assignment list command to verify that the AAD application has been successfully assigned to the role.
   • Specify the --assignee parameter with the AAD application ID.
   • Use the --scope parameter to specify the scope of the role assignment.

Using Python

1. Example 1: Enable Azure AD Conditional Access Policies
   • Use the azure-mgmt-authorization package to manage Azure AD Conditional Access Policies.
   • Write a Python script to create or update the policies based on your requirements.
   • Use the PolicyDefinitionsOperations and PolicyAssignmentsOperations classes to define and assign policies respectively.
   • Set the necessary properties such as displayName, conditions, grantControls, and sessionControls for the policies.
2. Example 2: Implement Role-Based Access Control (RBAC)
   • Use the azure-mgmt-authorization package to manage RBAC in Azure.
   • Write a Python script to create or update RBAC roles and assignments.
   • Use the RoleDefinitionsOperations and RoleAssignmentsOperations classes to define and assign roles respectively.
   • Set the necessary properties such as roleName, description, permissions, and assignableScopes for the roles.
3. Example 3: Enable Azure AD Privileged Identity Management (PIM)
   • Use the azure-mgmt-authorization package to manage Azure AD PIM.
   • Write a Python script to enable PIM for specific Azure AD roles.
   • Use the PimRoleAssignmentsOperations class to manage PIM role assignments.
   • Set the necessary properties such as principalId, resourceId, roleDefinitionId, and assignmentState for the role assignments.
