Communications Security

This is a copy of a handout I wrote for a talk on PGP to a group of activists at a dinner on January 29th, 2015. The intent was to provide a supplement to the practical, but narrow, walkthrough I’d given for those who wanted to dig deeper into data security in general.

Basic Security Principles

  1. Your security chain is only as strong as its weakest link. Make sure you understand the strengths and weaknesses of each link in your security chain. Take care to maintain the integrity of every link in your security chain. Using encryption will not help you if you composed your message on a compromised machine.
