Why each option

The 'Ban Sender' action in FortiGate DLP is unavailable for FTP traffic because it is an email-specific feature designed to block email senders.

AThe Ban Sender action is never available for FTP traffic.Correct

The 'Ban Sender' action within FortiGate DLP is exclusively designed for email protocols (like SMTP, POP3, IMAP) to identify and block problematic email addresses. Since FTP is a file transfer protocol and does not involve email senders, this action is technically irrelevant and therefore never available for FTP DLP rules.

BThe Ban Sender action needs to be enabled globally for FTP traffic on the FortiGate unit before

There is no global setting on a FortiGate to enable the 'Ban Sender' action for FTP traffic, as the feature is not designed for that protocol.

CFirewall policy authentication is required before the Ban Sender action becomes available.

Firewall policy authentication does not govern the availability of specific DLP actions; rather, it controls user access, while DLP actions are protocol-specific.

DThe Ban Sender action is only available for known domains. No domains have yet been added to

The 'Ban Sender' action targets email addresses, not general domains, and its availability is not contingent on pre-adding domains to the FortiGate for FTP traffic.
