3. Background
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 capability
When we use it?
Big files, Regulatory transactions, Audits, Sensitive information

4. SFTP Benefits 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 System admin from internal network opening ‘ssh’ on port 2222

5. Implementation and Applications
Implementations to understand secure data transfer ( protocols, software)
openssh-server, /usr/local/etc/sshd_config
Uses SSH-2
wxWidgets:
GnuTLS:
Key Authorizations
Certificates
The tradeoff of the availability, timeout and security must be weight against performance.

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

8. Pitfalls and Challenges
security vulnerability in applications and software
The Administrator user, password and software management and has to send an password to the users through an and this is not good method
Port forwarding and TLS
Data Volume ( Reliable Networks???)
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.
Data Accumalation.

9. Discoveries and Future work
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
