Connectors

For detailed instructions on how to configure a connector in Google SecOps, see Ingest your data (connectors).

Mandiant DTM – Alerts Connector

Use the Mandiant DTM – Alerts Connector to pull alerts from Mandiant Digital Threat Monitoring. To work with a dynamic list, use the alert_type parameter.

The connector requires the following parameters:

Parameters
`Product Field Name`	Required The name of the field where the product name is stored. The default value is `Product Name`.
`Event Field Name`	Required The name of the field used to determine the event name (subtype). The default value is `event_type`.
`Environment Field Name`	Optional The name of the field where the environment name is stored. If the environment field isn't found, the environment is set to the default value. The default value is `""`.
`Environment Regex Pattern`	Optional A regular expression pattern to run on the value found in the `Environment Field Name` field. This parameter lets you manipulate the environment field using the regular expression logic. Use the default value `.*` to retrieve the required raw `Environment Field Name` value. If the regular expression pattern is null or empty, or the environment value is null, the final environment result is `""`.
`Script Timeout`	Required The timeout limit (in seconds) for the Python process running the current script. Default value is 180 seconds.
`API Root`	Required The API root of the Mandiant instance. The default value is `https://api.intelligence.mandiant.com`.
`Client ID`	Required The Client ID of the Mandiant Digital Threat Monitoring account.
`Client Secret`	Required The Client secret of the Mandiant Digital Threat Monitoring account.
`Lowest Severity To Fetch`	Optional Lowest severity score of the alerts to fetch. If no value is provided, the connector ingests alerts with all severities. The parameter accepts the following severity values: `Low` `Medium` `High`
`Monitor ID Filter`	Optional A comma-separated list of monitor IDs to retrieve the alerts from.
`Max Hours Backwards`	Required Number of hours previously from when to fetch alerts. Default value is 1 hour.
`Max Alerts To Fetch`	Required Number of alerts to process for every connector iteration. Default value is 25.
`Disable Overflow`	Optional If selected, the connector ignores the overflow mechanism. Not selected by default.
`Use dynamic list as a blocklist`	Required If selected, the integration uses the dynamic list as a blocklist. Not selected by default.
`Verify SSL`	Required If selected, verifies that the SSL certificate for the connection to the Mandiant server is valid. Selected by default.
`Proxy Server Address`	Optional The address of the proxy server to use.
`Proxy Username`	Optional The proxy username to authenticate with.
`Proxy Password`	Optional The proxy password to authenticate with.

Connector rules

The connector supports proxies.

Connector events

There are two types of events for the Mandiant DTM – Alerts Connector: an event that is based on the main alert and an event that is based on a topic.

An example of the connector event based on the main alert is as follows:

{
   "id": "ID",
   "event_type": "Main Alert",
   "monitor_id": "MONITOR_ID",
