LARGE FILE TRANSFER SERVICE


This is an Agency service. ITCD provides this Web page as a courtesy to HQ users.

Large File Transfer (LFT) service is an alternative solution to sending and receiving e-mail messages with large file attachments. Accellion is the appliance (tool) selected to provide LFT service to the Agency. This service allows you to send and receive files, up to 10 GB, to other NASA users or individuals outside the Agency, without impacting the space available in your mailbox.

The LFT service is also available to users external to NASA who receive an invitation extended by a NASA user who has migrated to the NASA Consolidated Active Directory (NCAD). This invitation occurs in the form of a file being sent to the external user. Users must have an NCAD-enabled, OneNASA Account in order to initiate the LFT service.

How does LFT work?

When a file is sent, the recipient receives an e-mail message with a link to the temporary file location instead of the large attachment. The recipient has 7 days to download the file by clicking the link and logging in. External users will register and will use a temporary password of their choice.

Files sent using LFT are scanned for viruses and sent securely using SSL. However, please remember to use encryption when necessary. If you would normally encrypt the file before sending it by e-mail, encrypt it before sending it using LFT.

LFT will not replace your e-mail or any File Transfer Protocol (FTP) system currently in place.

How Secure is LFT?

Files sent using LFT are scanned for viruses and sent securely using SSL. However, remember to use encryption when necessary. If you would normally encrypt the file before sending it by e-mail, encrypt it before sending it using LFT.

Important!

The patch that was administered to remedy the Heartblead vulnerability invalidated the Federal Information Processing Standards (FIPS) 140-2 validation. FIPS 140-2 validation is required for the encryption of all sensitive government information at rest and in transit.

Until further notice, if you are using LFT to collaborate on information that is considered Sensitive but Unclassified (SBU), you must first encrypt using one of the following: When collaborating with internal users: Use Entrust.

  • When collaborating with internal users: Use Entrust.  
  • When collaborating with external users: Use another FIPS 140-2 validated encryption capability.

Distribution Lists

The use of distribution lists when using the LFT service is not recommended. In order for the Accellion appliance to send messages, it must expand the distribution list and send the message to each individual recipient. For various reasons, some distribution lists do not expand, which will result in some recipients not receiving the message.
