Disable Insecure Services
You should disable non-secure services if you are not using them. For example: TFTP and FTP are not secure protocols. These services are typically used to transfer firmware or software images to and from network devices and Prime Infrastructure. They are also used for transferring system backups to external storage. We recommend that you use secure protocols (such as SFTP or SCP) for such services.
To disable FTP and TFTP services:
Log in to Prime Infrastructure with a user ID with administrator privileges.
Select the Disable buttons for FTP and TFTP.
Restart Prime Infrastructure to apply the updated settings.
