As of vsftpd version 2.0.0, SSL / TLS support is provided. The SSL / TLS support provides the ability to encrypt FTP logins and subsequent commands, as well as the data transfers themselves. The encyption will, for example, stop the stealing of sensitive passwords via network snooping. By default, SSL support is disabled both at compile time and at runtime. Before considering enabling / using SSL support, there are some security considerations: - Only enable SSL if absolutely necessary. Enabling SSL will allow attackers to make use of any security problems in the OpenSSL libraries. Note that the OpenSSL libraries are a large quantity of code and have had the occasional security problem in the past. For example, your server might use virtual users to control access to non-sensitive download content. In this case, the passwords might not be worth securing with SSL. - After enabling SSL, consider restricting access to an SSL enabled server where feasible. For example, only the internal network might need access. In order to enable and use SSL support, you need the following: - vsftpd built with OpenSSL support. This is a decision your vsftpd packager made, or if you are building vsftpd yourself, edit "builddefs.h" and change the "#undef VSF_BUILD_SSL" to "#define VSF_BUILD_SSL". - "ssl_enable=YES" in your vsftpd.conf. - A SSL certificate. By default, an RSA certificate is looked for at the location /usr/share/ssl/certs/vsftpd.pem. To get an RSA certificate, either buy one from a certificate authority, or you can create your own self-signed certificate. If you have OpenSSL installed, you may find a "Makefile" in your shared certificates directory, e.g. /usr/share/ssl/certs. In that case, go to that directory and type e.g. "make vsftpd.pem". Then answer the questions you are asked. Alternatively, read the man page for "openssl". - Also be aware of the following SSL related parameters. Read the vsftpd.conf.5 manual page to learn about them: allow_anon_ssl, force_local_logins_ssl, force_local_data_ssl, ssl_sslv2, ssl_sslv3, ssl_tlsv1, rsa_cert_file, dsa_cert_file, ssl_ciphers.
