Dmitri Vitaliev and Frontline have published their manual for Digital Security and Privacy for Human Rights Defenders online. The manual is available at
http://www.frontlinedefenders.org/manual/en/esecman/.
The publication is "dedicated to all human rights defenders, continuing their difficult and honest work, also on the Internet. Some of these people are in prison due to their activities on the Internet. Mohammed Abbou is serving a 3,5 year prison term in Tunisia for publishing online an article that compared Tunisian prisons to Abu Ghraib."
All the software mentioned in the manual is available in the NGO in a Box - Security Edition. The software and manuals can be downloaded freely via http://security.ngoinabox.org/html/en/index.html.
