Anomalous network monitoring, user behavior detection and database system
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for network monitoring, user account compromise determination, and user behavior database system. The system monitors network actions of user accounts including user account access across multitudes of network accessible systems, determines user account transitions, and determines different types of high-risk user behavior indicative of compromise. Network actions can be obtained from generated information by the network accessible systems, and correlated across additional data sets including contextual ones. User interfaces are generated describing network actions of user accounts, and are configured for user interaction, which cause generation of updated user interfaces and access to electronic data sources to determine information relevant to the user interaction.
