I am the co-author of Information Security for Journalists, a handbook for the Centre for Investigative Journalism, published July 2014. This book is free to download and periodically revised. You can find the latest edition here.
I studied Politics and Psychology at the University of Cambridge, conducting the first research into the reversal of system justification, using WikiLeaks as a stimulus.
