2014-05-28: TrueCrypt currently has security issues and is not recommended.

If you’re running GNU/Linux, dm-crypt with LUKS is the recommended encryption option.

Gentoo GNU/Linux maintains a guide for dm-crypt with LUKS.

Arch GNU/Linux maintains a guide to dm-crypt with LUKS. Also useable for Parabola GNU/Linux.

Bitmessage is a promising alternative to email, but it has not yet been audited by security professionals. Use at your own risk. If you decide to try out Bitmessage, make sure to generate a completely random ID to greatly reduce the probability of ID collisions.

RetroShare has not been thoroughly audited by security professionals for possible security issues.

Switching from a proprietary service like Gmail to one of the more transparently-run email services on PRISM Break is the first step to a secure email account.

The second step is getting you and your contacts to encrypt your plain text messages with PGP encryption. This section contains free email clients that support PGP.

Read the Email Self-Defense guide by the Free Software Foundation to learn how to encrypt your email messages.

Here is a guide by Security In A Box to encrypting your email with Mozilla Thunderbird, GNU Privacy Guard (GPG), and Enigmail.

Find out more about the differences between Mozilla Thunderbird and Icedove.

“Off-the-Record Messaging, commonly referred to as OTR, is a cryptographic protocol that provides strong encryption for instant messaging conversations. OTR uses a combination of the AES symmetric-key algorithm, the Diffie–Hellman key exchange, and the SHA-1 hash function. In addition to authentication and encryption, OTR provides perfect forward secrecy and malleable encryption.

The primary motivation behind the protocol was providing deniability for the conversation participants while keeping conversations confidential, like a private conversation in real life, or off the record in journalism sourcing.”

Note that Pidgin stores your IM account passwords in plain text. You can avoid this by (1) not saving your password in Pidgin, (2) encrypting your file system, or (3) storing your Pidgin password securely with the Debian package pidgin-gnome-keyring.

Pidgin with OTR and dbus enabled has a local security bug. See the upstream bug report for more information and possible workarounds.

A beginner’s guide to running your own mail server is available here: “NSA-proof your e-mail in 2 hours”.

Kolab integrates Roundcube into its webclient and offers desktop clients as well. Recent versions also feature a file cloud turning it into a complete solution for personal information management.

What is an MTA?

“Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. An MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol.

The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.”

Apple, Google, and Microsoft are allegedly a part of PRISM. Their proprietary operating systems cannot be trusted to safeguard your personal information from the NSA. We have two free alternatives: GNU/Linux and BSD.

GNU/Linux has a much larger community to help you with the transition. It’s recommended that you begin your explorations by looking for a GNU/Linux distribution that suits your needs. Additionally the Free Software Foundation hosts a list of completely Free distributions.

Debian has a long tradition of software freedom. Contributors have to sign a social contract and adhere to the ethical manifesto. Strict inclusion guidelines make sure that only certified open source software gets packaged in the main repositories. You may also want to disable contrib and non-free repositories.

Fedora is a community edition that serve as the stable basis for enterprise ready GNU/Linux distributions with commercial support. Companies all over the world trust Red Hat Inc. because of their transparency throughout the whole development process.

Canonical’s Ubuntu is not recommended by PRISM Break because it contains Amazon ads and data leaks by default. GNU/Linux distributions based on Ubuntu are also currently not recommended due to several other reasons.

Utilizar a distribuição 'live' Tails é a forma mais fácil e rápida de proteger um sistema operacional. Tudo que deve se fazer é criar um CD ou USB 'bootável' com os arquivos indicados e pronto. Todo o resto será configurado para você.

Uma imagem de máquina virtual como o Whonix deve ser execuada dentro de uma solução de virtualização como o VirtualBox. VirtualBox pode ser instalado no Windows, Linux, macOS e Solaris. Isto significa que se você não puder substituir seu Windows ou macOS por qualquer motivo, você pode instalar o VirtualBox e utilizar o Whonix para ampliar sua privacidade e segurança.

Installing your own add-ons into the Tor Browser is not recommended, as they may bypass Tor or otherwise harm your anonymity and privacy. Check the EFF's Panopticlick to see how trackable your browser configuration is by third parties.

If you're using a Firefox-based browser, you can safeguard your browsing habits and stop advertising companies from tracking you by installing uBlock Origin, Request Policy, and HTTPS Everywhere.

A more advanced alternative to Request Policy would be uMatrix.

Install NoScript and enable ‘Forbid scripts globally’ to improve the security of your browser by preventing 0day JavaScript attacks. This is a drastic option as it will render many websites unusable as they rely heavily on JavaScript. NoScript offers a whitelist you can use to selectively enable JavaScript for sites you trust, but this is considered especially bad for your anonymity if you're using NoScript with the Tor Browser Bundle.

Why is Adblock Plus not recommended? Adblock Plus shows “acceptable ads” by default, which works against the purpose of the add-on. Either disable acceptable ads or use uBlock Origin instead.

Use a combination of Tor Browser and a free web browser of your choice to the surf the web.

Try to use Tor Browser as often as possible. Browsing is slower with Tor, but far more secure.

Note: Mozilla Firefox is technically not completely free software, as Mozilla recommends non-free add-ons on their website.
