Signing
SMB messages can be signed. If you want Fusion File Share server to accept only signed messages and drop all unsigned messages, configure the ‘require_message_signing’ setting to ‘true’:
require_message_signing = true
note
This setting may affect performance, but it will improve security.
If this setting is ‘false’, Fusion File Share server still replies with signed messages if the request message is signed. In this case, it is the client’s responsibility to decide which messages should be signed and which should not.
