Create a custom FTP Security Profile alongside the system default named 'ftp_security'. 3. Navigate to Security :: Protocol Security : Profiles Assignment : FTP. 4. From the Assigned Security Profile drop-down menu, choose the newly created custom FTP Security Profile, instead of the pre-selected system default 'ftp_security'.
