Secure File Transfer

Introduction

Data delivery over the Internet can be simple, convenient, and cost-effective - but it must also be secure. Traditional file transfer methods do not provide adequate security, transmitting account information like user names, passwords, and data in the clear where they can be easily intercepted. The current version of Secure Shell (SSH2) provides a secure alternative. This paper explains the Secure Shell File Transfer Protocol (SFTP) and presents specific applications for system administration, finance, health care, and business-to-business. VanDyke Software clients and servers provide secure file transfer capabilities for Windows and are interoperable with SSH software on other platforms.
