Integrate McAfee GTI file reputation with Secure SD-WAN

Integrating Secure SD-WAN with McAfee Global Threat Intelligence file reputation services allows access control based on the scan results.

Before you begin

Note: This feature requires a separate license.

Integrating McAfee GTI requires enabling McAfee GTI File Reputation and authorizing the use of the McAfee GTI service.

The McAfee GTI database contains classifications of files. When a file transfer matches a rule in the File Filtering Policy that applies McAfee GTI file reputation, the Secure SD-WAN Engine sends a hash of the file to the McAfee GTI cloud. McAfee GTI file reputation compares the hash of the file against the McAfee GTI database.

Only a hash of the file is sent to the McAfee GTI cloud. No other data or telemetry information is sent to the McAfee GTI cloud.

Global System Properties dialog box — Global Options tab

Use this tab to configure general settings for the SMC and Secure SD-WAN Engines.

You can also use this tab to:

  • Authorize McAfee® Global Threat Intelligence™ (McAfee GTI). Only administrators with unrestricted permissions (superusers) can enable McAfee GTI.
  • Set the expiration time for one-time passwords that are generated when you save the initial configuration for an Secure SD-WAN Engine.
  • Import Snort configuration files globally to configure default settings for Snort inspection for all Secure SD-WAN Engines.

All settings are optional.

Option Definition
Enable McAfee Global Threat Intelligence (GTI) and McAfee Threat Intelligence Exchange (TIE) usage When selected, enables McAfee GTI usage.
Note: McAfee Threat Intelligence Exchange (TIE) is no longer supported in Secure SD-WAN 6.10 and higher.
One-Time Passwords Expire After Defines the expiration time for one-time passwords that are generated when you save the initial configuration for an Secure SD-WAN Engine. If the one-time password is not used, it automatically expires after the expiration time has elapsed.

By default, one-time passwords expire after 30 days.

Snort Configuration The externally created Snort configuration .zip file that contains the Snort configuration files and rules for Snort inspection.
  • Click Browse to select a file.
  • Click None to remove a previously imported file.
  • Click Export to export the Snort configuration file.

All Secure SD-WAN Engines for which Snort inspection is enabled use the global Snort configuration by default.

Settings in the Snort configuration .zip file for an individual Secure SD-WAN Engine are combined with the settings in the global Snort configuration .zip file. If any configuration files in a Snort configuration .zip file for an individual Secure SD-WAN Engine have the same files name and paths as configuration files in the global Snort configuration .zip file, the overlapping files in the global Snort configuration .zip file are ignored.
