Security

A guide for practicing safe web.

Think

Security is important, and you can't practice these guidelines without understanding them. Make sure you understand each guideline, why it exists, and how to follow it.

Failing to follow these guidelines will likely put you, your team, and your deployed services at risk of compromise or loss of privacy.

Secure Employee Access and Communication

The following guidelines apply to how you as an individual secure access to your systems (laptop, accounts, etc.) and communication (email, etc.).

Protecting Personal or Identifying Information

See protecting personal or identifying information.

Using Passwords

• Use a unique password for every account you create.
• Use a tool like pwgen or 1password to generate random passwords.
• Use a tool like GnuPG to encrypt passwords if you need to share them with somebody.

Encryption

• Ensure disk encryption on your laptop.
• Use a PGP signature in an email if you want somebody to trust that you wrote it.
• Use PGP to check email signatures if you want to know who wrote it.
• Use PGP to encrypt emails if you want to be sure nobody but the recipient is reading it.
• Use ultimate trust for your own keys.
• Use full trust for keys you have verified in person or via a secure video chat.
• Don't share your private key with anyone, including services like Keybase.
• Keep at least one backup of your private key and revocation certificate in a secure location, such as a thumb drive.

Physical Security

The following guidelines apply to how we physically secure our laptops and mobile devices that may contain customer or user data.

• Lock your device when you are away from it.
• Don't leave your devices unattended in an unsecured area.
• Install a device tracking and remote data wipe tool such as Prey.

Application Security

The application security guidelines apply to how we develop software on behalf of ourselves and clients.

Handling Vulnerabilities

The following guidelines apply to how we handle security incidents.

Reporting

When someone finds a possible security issue in our software, we encourage them to report it to our [email protected] email address.

When an email comes in through this channel, reply quickly with confirmation (and CC [email protected] so others know that it has been handled) and the information for the thoughtbot PGP key, which is located at https://thoughtbot.com/security.

Reviewing, Logging and Following Up

When an encrypted message comes in, post the exchange to a new Hub Message in the security interest, and keep the thread updated with new messages as they appear.

Further discussion of security takes place in the Security Basecamp.
