Cybersecurity expert and advocate of liberal encryption policy, Susan Landau, explores this challenge and the need for maintaining cybersecurity in her new book “Listening in: Cybersecurity in an Insecure Age.” Last week at the Hoover Book Soiree, Benjamin Wittes and  Susan Landau discussed the issues behind encryption, whether law enforcement can manage without signals content, the impact of end-to-end encryption on security, and much more.
