Integrate TIE file reputation with Forcepoint NGFW

Integrate Forcepoint NGFW with McAfee® Data Exchange Layer (DXL) and McAfee® Threat Intelligence Exchange (TIE) file reputation to receive file reputation data from the TIE server. Use the reputation data in file filtering to improve the malware detection coverage of Forcepoint NGFW.

Before you begin

To generate the DXL certificates required for the exchange of file reputation data with the TIE server, you must configure an ePO Server element and initialize the ePO Server SSL context.

Note: Integrating TIE file reputation requires enabling McAfee TIE and authorizing the use of the McAfee TIE service.

DXL is a framework of client software and brokers that enables the exchange of real-time encrypted file information between integrated security components in the network environment. The TIE server uses DXL to collect file reputation data. When Forcepoint NGFW is integrated with DXL and TIE file reputation, Forcepoint NGFW engines can request and automatically receive up-to-date file reputations from the TIE server. This ensures that NGFW Engines always have the latest file reputations available for use in file filtering.

Use of TIE file reputation does not require a separate license in the SMC. However, the DXL service components, such as the DXL broker, might require a separate DXL license.

Note: You cannot use TIE file reputation with Sidewinder Proxies. If the File Filtering Policy uses TIE file reputation, it is ignored for traffic that uses Sidewinder Proxies. If no other scanners are available, file transfers are allowed or discarded according to the selection for the Action When No Scanners Are Available option.
