This is a module for Office 365 logs received via one of the Office 365 API endpoints. It currently supports user, admin, system, and policy actions and events from Office 365 and Azure AD activity logs exposed by the Office 365 Management Activity API.
Read the quick start to learn how to set up and run modules.
Configure the moduleedit
You can further refine the behavior of the
o365 module by specifying
variable settings in the
modules.d/o365.yml file, or overriding settings at the command line.
Each fileset has separate variable settings for configuring the behavior of the
module. If you don’t specify variable settings, the
o365 module uses
When you specify a setting at the command line, remember to prefix the
setting with the module name, for example,
audit fileset settingsedit
audit fileset uses the Office 365 Management Activity API to retrieve
audit messages from Office 365 and Azure AD activity logs. These are the same
logs that are available under Audit Log Search in the Security and
Once this application is registered note the Application (client) ID and the Directory (tenant) ID. Then configure the authentication in the Certificates & Secrets section.
o365.yml using client-secret authentication:
audit: enabled: true var.application_id: "<My Azure AD Application ID>" var.tenants: - id: "<My Tenant ID>" name: "mytenant.onmicrosoft.com" var.client_secret: "<My client secret>"
Certificate-based authentication is specially useful when monitoring multiple tenants. Example configuration:
audit: enabled: true var.application_id: "<My Azure AD Application ID>" var.tenants: - id: "<Tenant A ID>" name: "tenantA.onmicrosoft.com" - id: "<Tenant B ID>" name: "tenantB.onmicrosoft.com" var.certificate: "/path/to/certificate.pem" var.key: "/path/to/private_key.pem" var.key_passphrase: "my_passphrase" # (optional) for encrypted keys
Finally you need to add permissions in the API permissions section and grant it admin consent. Click on Add permission and select Office 365 Management APIs. The needed permissions are:
Once the required permissions are added, click the Grant admin consent button. Note that it can take a while for the required permissions to be in effect, so it’s possible that you observe some permission errors when running Filebeat right away.
This module supports custom endpoints for on-prem deployments as well as
alternative endpoints (GCC High endponts, U.S. DoD, European Union, etc). In
order to point the module to an alternative endpoint, you need to adjust the
resource variables accordingly. For example:
var.api: # default is https://login.microsoftonline.com/ authentication_endpoint: https://login.microsoftonline.us/ # default is https://manage.office.com resource: https://manage.office365.us
- The Application ID (also known as client ID) of the Azure application.
A list of one or more tenant IDs and name pairs. Set the
idfield to the tenant ID (also known as Directory ID). Set the name to the host name for the tenant, that is, the Office 365 domain for your organization.
The client-secret (api_key) used to authenticate your Azure AD application. This
option cannot be specified at the same time as the
Path to the certificate file used for client authentication. This option cannot
be specified at the same time as the
- Path to the private key file used for client authentication.
The passphrase used to decrypt an encrypted key stored in the configured
var.keyfile. Only set this option when the key is encrypted.
The list of content-types to subscribe to. By default, it subscribes to all known content-types:
Advanced configuration optionsedit
The following configuration options are only recomended in case of problems.
They must be nested under a single
var.api key, like this:
var.api: authentication_endpoint: https://login.microsoftonline.com/ resource: https://manage.office.com max_retention: 168h poll_interval: 3m max_requests_per_minute: 2000 max_query_size: 24h
The authentication endpoint used to authorize the Azure app. This is
https://login.microsoftonline.com/by default, and can be changed to access alternative endpoints.
The API resource to retrieve information from. This is
https://manage.office.comby default, and can be changed to access alternative endpoints.
The maximum data retention period to support.
168hby default. Filebeat will fetch all retained data for a tenant when run for the first time. The default is 7 days. Adjust it if your tenant has a different retention period.
The interval to wait before polling the API server for new events. Default
The maximum number of requests to perform per minute, for each tenant. The
2000, as this is the server-side limit per tenant.
The maximum time window that API allows in a single query. Defaults to
24hto match Microsoft’s documented limit.
