In the ongoing cybersecurity battle between attackers and defenders, attackers are quick to gain access to critical systems and quick to extract stolen data. Meanwhile, defenders are distressingly slow to detect that a compromise even occurred. This is one key takeaway in Verizon’s 2019 Data Breach Investigations Report (DBIR). The newest edition of this annual cybersecurity report is built from analysis of 41,686 security incidents, including 2,013 confirmed data breaches. Data sets for the report were collected from 73 different sources, including publicly-disclosed security incidents, cases provided by the Verizon Threat Research Advisory Center (VTRAC) investigators, and information shared by a variety of external collaborators.
