Digital communications security ideas activists should be thinking about

Everyone's situation is different! But there are common threads and we can learn from each other.

Basic Themes

Security isn't just one thing. You can think about your risks more clearly if you understand what kinds of concerns you have. Four major security themes that are worth thinking over are:

Privacy
Who can see my communications? Is it only the people I expect? What does privacy mean when sending the same message to many people? Who can breach the privacy? Am I protecting the privacy of my members or the people I'm working with?
Authenticity
When I receive messages, how do i know who they're from? Are they really from that person? When I communicate messages where my identity is important and relevant, how can the people I'm communicating with know that my messages are really from me?
Anonymity
When I want to communicate without divulging my identity (whistleblowing, etc), how can I be sure that my identity is protected?
Reliability/Access
Is the communications medium i'm using something I can rely on? Who controls the medium? Can it be shut down or interrupted? Will it be there when I need it urgently?

Discussing this themes with your fellow organizers and activists is an excellent first step toward building security. Keep in mind that improvements in one area (like privacy) may lead to a decrease in security in another area (like reliability/access).

One resource you may find helpful is a worksheet developed by the Progressive Technology Project. Try filling out both pages.

Resources

Sending messages

One activity we engage in every single day is sending each other messages. Sending messages crosses all four themes, so picking the right method will depend on, for example, how you compare your need for privacy with your need for reliability.

Email

Email is the oldest and most universal form of exchanging messages.

  • OpenPGP is a method that allows you to encrypt your messages in a way that not even your Internet provider can decipher them. However, it is hard to setup and requires both you and the recipient are using it
  • How do you get your email? Webmail means going to a web site and entering your username and password to access your email. It is very convenient, you can access your email anywhere even if you don't have your phone or computer. However, it also means that all of your email is saved on the server, which could be subpoenaed. Alternatively, you can use a desktop or mobile client that downloads your email, removing it from the server. However, your phone or computer can be lost or subpoenaed. There is no right answer! But at MF/PL you can choose between webmail or a client based on your needs.

Other forms of instant messaging

  • All May First/People Link members can use jabber - which works on your computer and on your phone and supports end-to-end encryption.
  • Another popular, free and secure messaging applications is called Signal by Whisper Systems.

Web sites

Web sites also cross many different security themes. Your web site may contain sensitive data that should only be scene by people with the right access. Also, your web site may track visitors, which could be used in a lawsuit to against your allies.

  • If your web site address does not have a padlock next to it (and is not accessible via https) - then all traffic to and from your site is in plain text and can be watched by anyone with the legal or technical means to intercept it. If you use a username and password to login to your site - that information is also sent without encryption. At May First/People Link, you can enable encryption with a few clicks thanks to the Lets Encrypt project.
  • If you are using your site to organize people, and your campaign is successful, you could find yourself under criminal investigation in which logs of every visitor to your site are subpoenaed. Find out how to turn off logging on your site to avoid being placed in this position.
  • May First/People link has an backup system in place. However, if downtime is critical, we encourage you to mainain your own backup as well. Deciding your backup strategy will require a trade-off between privacy (you don't want backup copies lying around) and reliability (you want to have the data to get your site back online at a moment's notice)
