Tokyo, December 10, 2015 - NEC Corporation (NEC; TSE: 6701) today announced the development of a'system operations-visualization and anomaly-analysis technology' that uses artificial intelligence (AI) to automatically detect unknown cyber-attacks against social infrastructure and enterprise systems. The new technology learns (through machine learning) the normal state of OS-level operations (program start-up, file access, communications, etc.) for entire ICT systems, including PCs and servers. It then carries out real-time comparisons and analysis of current operations in the system's normal state and automatically isolates particular points that deviate from the normal state by using system operation tools and Software-Defined Networking (SDN). Further, a detailed knowledge of the system behavior makes it possible to identify the extent of damage 90% faster than the time required in conventional manual investigation. Accurate anomaly detection and quick specification of damaged areas by the new technology minimize the damage from cyber-attacks and enable recovery without stopping an entire user-system.
