The 2014 US State of Cybercrime Survey was co-sponsored by PwC, CSO magazine, the CERT® Division of the Software Engineering Institute at Carnegie Mellon University, and the United States Secret Service. Cybersecurity leaders from these organizations worked together to evaluate survey responses from more than 500 executives of US businesses, law enforcement services, and government agencies. We identified requirements for effective cybersecurity and evaluated these practices against current and evolving adversaries, threats, and known attacks across the digital ecosystems of private and public organizations.
