Firepower detects malware in FTP but doesnt detects in TFTP Transfer

[malikyounas]

I am  testing the firepower (ver. 6.0.0.1-26)  on ASA 5525X (9.5.3).

I have access control policy applied with file and malware policies in it which are to block malware.

I have an issue where a test a malware file transfer using TFTP isnt detected by the module and is allowed to pass through. However, module detects the file If I try to use FTP for file transfer.

Any idea why it would not detect using TFTP and how it detect when using FTP.

Found answer myself, only certrain protocols are supported for inspection and TFTP is not one of them.
