With its joint expertise in security and technology, Israel has become a cyber security powerhouse over the past decade. The former head of Israeli cyber policy, Eviatar Matania, was key in that evolution. He founded and led the Israel National Cyber Bureau under former prime minister Benjamin Netanyahu and recently co-wrote "Cybermania," a book tracing Israel's cyber revolution. He joined us for Perspective to discuss abuse of Israel's Pegasus surveillance technology, the need for international regulation and the relationship between cyber and conventional warfare.
