A "Block FTP" response rule is set up in Enforce and file containing sensitive information attempts to be moved using an FTP client. The incident is logged on the Enforce Server, but the FTP file transfer is not blocked.
This behavior has been observed with multiple different FTP clients when McAfee Web Gateway is set up as the proxy. The issue has occurred with multiple versions of McAfee Web Gateway as well, including version 7.5.2 and 7.7.x.
Our software communicates appropriately to the McAfee Web Gateway proxy, but something in the configuration settings on the McAfee Web Gateway proxy doesn't allow the block to occur.
Contact McAfee support to obtain configuration information specific to your implementation that allows blocking to take place when our Block FTP rules are met.
