Namespace: microsoft.graph.security

Important

APIs under the /beta version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported. To determine whether an API is available in v1.0, use the Version selector.

Get a list of custom detection rules. With custom detections, you can proactively monitor for and respond to various events and system states, including suspected breach activity and misconfigured assets in their organization network. Custom detection rules, which are written in Kusto query language (KQL), automatically trigger alerts and response actions once there are events matching their KQL queries.

This API is available in the following national cloud deployments.

Global service	US Government L4	US Government L5 (DOD)	China operated by 21Vianet
✅	❌	❌	❌

Permissions

Choose the permission or permissions marked as least privileged for this API. Use a higher privileged permission or permissions only if your app requires it. For details about delegated and application permissions, see Permission types. To learn more about these permissions, see the permissions reference.

Permission type	Least privileged permissions	Higher privileged permissions
Delegated (work or school account)	CustomDetection.Read.All	CustomDetection.ReadWrite.All
Delegated (personal Microsoft account)	Not supported.	Not supported.
Application	CustomDetection.Read.All	CustomDetection.ReadWrite.All

HTTP request

GET /security/rules/detectionRules

Optional query parameters

This method supports some of the OData query parameters to help customize the response. For general information, see OData query parameters.

Request headers

Name	Description
Authorization	Bearer {token}. Required. Learn more about authentication and authorization.

Request body

Don't supply a request body for this method.

Response

If successful, this method returns a 200 OK response code and a collection of detectionRule objects in the response body.

Examples

Request

The following example shows a request.

GET https://graph.microsoft.com/beta/security/rules/detectionRules?$top=3


// Code snippets are only available for the latest version. Current version is 5.x

// To initialize your graphClient, see https://learn.microsoft.com/en-us/graph/sdks/create-client?from=snippets&tabs=csharp
var result = await graphClient.Security.Rules.DetectionRules.GetAsync((requestConfiguration) =>
{
	requestConfiguration.QueryParameters.Top = 3;
});

Important

Microsoft Graph SDKs use the v1.0 version of the API by default, and do not support all the types, properties, and APIs available in the beta version. For details about accessing the beta API with the SDK, see Use the Microsoft Graph SDKs with the beta API.
