FTP communication is not secure, all communication is plain text and can be easily captured. Despite this serious weakness, few do anything to secure it. There are simple ways to correct this with VSFTPD.

SSL/TLS With FTP

FTP communication is not secure, all communication is plain text and can be easily captured. Despite this serious weakness, few do anything to secure it. There are simple ways to correct this with VSFTPD.FTPS is also known as FTPS Secure or FTP-SSL. What FTPS does is add the Transport Layer Security (TLS) and the Secure Sockets Layer (SSL) to the normal FTP on the same port 21.

RetroShare is a Open Source cross-platform, private and secure decentralised communication platform.It lets you to securely chat and share files with your friends and family, using a web-of-trust to authenticate peers and OpenSSL to encrypt all communication.

"...GNU Telephony Secure Calling is intended to make it both possible, and easy, for individuals, private organizations, and public institutions to deploy secure realtime voice and video communications (VoIP) both in closed and openly accessible networks, and to do so in a manner which helps make passive and warrantless communication intercept of private communication a thing of the past.

This Ubuntu 9.10 Mini-Course will help you set up a secure an Ubuntu 9.10 Server using Postifx, Dovecot and Thunderbird with TLS and SMTP AUTH. The goal of this configuration is to create a secure mail server using encrypted communication to retrieve mail and to send mail through your mail server.

For the last few years I had occasionally been working on what is called the GNU Telephony Secure Calling initiative.

The GNU Privacy Guard is GNU's tool for secure communication and data storage. It can be used to encrypt data, create digital signatures, help authenticating using Secure Shell and to provide a framework for public key cryptography. It includes an advanced key management facility and is compliant with the OpenPGP and S/MIME standards.

FTP is a very insecure protocol because all passwords and all data are transferred in clear text. By using TLS, the whole communication can be encrypted, thus making FTP much more secure. This article explains how to set up ProFTPd with TLS on an Ubuntu 11.04 server.
