2. 1. Background Why SFTP? What is it? When we use it? 1. SFTP implementation and Application 2. Pitfalls and challenges 3. Future work

3. Why SFTP? We are shutting off clear-text FTP access because when you log in with your username and password, people snooping on the network can capture all information sent. What is SFTP? SSH File Transfer Protocol (also Secret File Transfer Protocol, Secure FTP, or SFTP) is a network protocol that provides file access, file transfer, and file management functionalities over any reliable data stream. (SSH) version 2.0 to provide secure file transfer capabilitynetwork protocolfile accessfile transferfile managementdata stream When we use it? Big files, Regulatory transactions, Audits, Sensitive information

4.  Encrypted username/passwords  Encrypted data transfers  Prevent users from reading other users ftp data  Prevent full command line access from outside users  Prevent full command line access from any internet facing connection  Allow full command line access to Unix admin from internal network opening ‘ssh’ on 2222

5.  Implementations to understand secure data transfer openssh-server, /usr/local/etc/sshd_config Uses SSH-2 wxWidgets: 2.8.11 GnuTLS: 2.10.2 Key Authorizations Certificates

6. Filezilla (Open Source) (uses as client) WS-FTP Pro (client) Open-ssh WinSCP FLASHFXP SEEBURGER( cloud computing) Cyberduck (Cloud computing)

7. Benefits are Secret sharing files and security, integrity, faster then traditional posting Tradeoffs are necessary like performance and Exchanging keys or passwords

8.  security vulnerability in applications and software  The Administrator user, password and software management and has to send an password to the users through an email and this is not good method  If the users does not clean up the old data and the files may be filled up the disk and admin has to come up with cron jobs to clean.  Leaving very big files and old data can cost the organizations

9.  Two formidable challenges to privacy: ◦ Data need to transfer forever and how can we make it secure all the time. ◦ Human mistakes ( giving wrong permissions to wrong people) ◦ Disclosures of data and keys have become commonplace ◦ Some of the applications came online to provide secure transfer and they suffer from data leakage.  (SEEBURGER Managed File Transfer Wins Award for Data Leakage Protection) beyond SFTP.  Textastic 2.1 for iPad adds SFTP support and more FTP options  Make easy use of sftp for wireless
