The FTP Server can provide audit data in the form of SMF records. SMF record type 119, the TCP/IP Statistics record, can be written with the following subtypes:

70 – Append
70 – Delete and Multiple Delete
72 – Invalid Logon Attempt
70 – Rename
70 – Get (Retrieve) and Multiple Get
70 – Put (Store and Store Unique) and Multiple Put

SMF data produced by the FTP Server provides transaction information for both successful and unsuccessful FTP commands. This data may provide valuable information for security audit activities. Type 119 records use a more standard format and provide more information.
