McAfee Threat Intelligence Exchange v2

This Integration is part of the McAfee Threat Intelligence Exchange Pack.#

Use the McAfee Threat Intelligence Exchange (TIE) integration to get file reputations and the systems that reference the files. Connect to McAfee TIE using the McAfee DXL client. This integration was integrated and tested with version 2.0 of McAfee Threat Intelligence Exchange V2

Some changes have been made that might affect your existing content. If you are upgrading from a previous version of this integration, see Breaking Changes.

Detailed Instructions#

This section includes information required for configuring an integration instance.

Prerequisites - Connect to McAfee Threat Intelligence Exchange (TIE) using the DXL TIE Client#

To connect the McAfee TIE using the DXL TIE client, you need to create certificates and configure DXL. For more information, see the documentation. After you complete this configuration, you will have the following files:

Broker CA certificates (brokercerts.crt file)
Client certificate (client.crt file)
Client private key (client.key file)
Broker list properties file (brokerlist.properties file)

Important: These are the actual certificates, not request certificates.

set-file instruction#

To use the tie-set-file-reputation command, you need to authorize the client (Cortex XSOAR) to run the command. Follow the instructions to do so. In step 4, instead of selecting Active Response Server API, select TIE Server Set Enterprise Reputation.

Dependencies (Python packages)#

You don't need to install the packages, they are included in the Docker image.
