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.

Slackware Linux maintains a guide to dm-crypt with LUKS.

Transparency in this context means that individual programs don't need to manage encryption of their own data, because this is provided equally for all programs by the encryption tool (like dm-crypt). More details on this in the Wikipedia.

Email Alternatives
Notes

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.

Email Clients
Notes

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.

Email Encryption
Notes

“Pretty Good Privacy (PGP) is a data encryption and decryption computer program that provides cryptographic privacy and authentication for data communication. PGP is often used for signing, encrypting and decrypting texts, e-mails, files, directories and whole disk partitions to increase the security of e-mail communications.”

PRISM Break does not recommended S/MIME email encryption because of its reliance on third-party certificates from central authorities. Read more here.

Experimental PGP projects worth looking at are OpenPGP Keychain (a APG fork) and GnuPG for Android by the Guardian Project.

File Storage & Sync
Notes

Cloud file storage is also available via Chwala/iRony components of Kolab with the capability to integrate various storage backends. Files are accessible via storage layer access options, WebDAV and Kolab web interface integrating Roundcube.

Tarsnap is not recommended on PRISM Break due to its lack of anonymous payment options and strict copyright on the client that makes it difficult to replace the service in the event Tarsnap is shut down.

BitTorrent Sync, MEGA, and SpiderOak are services that are built on either partially or fully proprietary software. They will not be recommended on PRISM Break until they open source the entirety of their codebase.

With closed source software, you need to have 100% trust in the vendor because there's nothing except for their morality in the way of them leaking your personal information. Even if you can vouch for their integrity, proprietary software invariably has more uncaught security bugs and exploits because there are fewer eyes examining the source code.

Another alternative to cloud storage is local backup with external hard drives and USB flash drives. This method is reliably more secure than storing data on a network, but comes at a convenience cost.

Instant Messaging
Free Recommendations
Notes

“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.

The Guardian Project hosts a fantastic how-to guide to chatting securely on Android with ChatSecure.

Threema is not recommend by PRISM Break as it is closed source software. Freely available source code is a necessary condition for privacy and security.

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.”

Mesh Networks
Notes

A mesh-networks is a decentralized peer-to-peer network, with user-controlled physical links that are usually wireless.

“Mesh networking (topology) is a type of networking where each node must not only capture and disseminate its own data, but also serve as a relay for other nodes, that is, it must collaborate to propagate the data in the network.”

Operating Systems
Free Recommendations
Notes

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. Contributers 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.

Gentoo describes itself as a meta-distribution. The source code is compiled to binary applications on the user's machine allowing near-unlimited adaptability and complete retraceability of the program logic.

Both Fedora and openSUSE are community editions that serve as the stable basis for enterprise ready GNU/Linux distributions with commercial support. Companies all over the world trust Red Hat Inc. and SUSE Linux GmbH because of their transparency throughout the whole development process.

Parabola GNU/Linux is effectively 99% Arch Linux with a de-blobbed kernel and a meta-package that blocks unfree licenses. Both of these features can be installed under Arch.

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.

A live distribution like Tails or Liberté Linux is the fastest and easiest way to a secure operating system. All you have to do is create a bootable CD or USB drive with the files provided and you’re set. Everything else will be preconfigured for you.

A virtual machine (VM) image like Whonix is designed to be run inside of a virtualization package like VirtualBox. VirtualBox can be installed on Windows, Linux, OS X, and Solaris. This means that if you're stuck using Windows or OS X for whatever reason, you can install VirtualBox and use Whonix to increase your privacy and security.

Web Browser Addons
Notes

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 Adblock Edge, Disconnect, and HTTPS Everywhere.

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 the Adblock Edge fork instead.

Ghostery is an alternative anti-tracker add-on to Disconnect. While the code is available, the license is currently proprietary.

Proprietary
Web Browsers
Notes

Try to use Tor Browser Bundle (TBB) for all of your web surfing. It will offer you far better anonymity than any other browser. Make sure to learn the basics of Tor before using it. If the site you want to visit will not work in the TBB, try Firefox intead, but realize these browsers do not anonymize your ip by default.

TBB notes: Using the TBB to sign into websites that contain your real ID is counterproductive, and may trip the site's fraud protection. Make sure to check for HTTPS before signing in to a website through Tor. Signing into HTTP websites can result in your ID being captured by a Tor exit node.

Firefox notes: This browser uses Google search by default: replace it with a more private alternative. Another debranded alternative to Firefox is Iceweasel, a browser for Debian-based distributions.

Why are Chromium, SRWare Iron, et al. not recommended on PRISM Break? More info here.

Warning for mobile devices & Tor: Websites using HTML5 <video> tags will leak <video>-related DNS queries and data transfer outside of Tor.
