Intelligent security engine and intelligent and integrated security system using the same

摘要

A firewall interconnects and controls access between external and internal networks, and a plurality of security agents monitor a data flow and system calls over the internal network. An intelligent security engine (ISE) is for analyzing an alert message, a traffic information and an event information transferred from the plurality of security agents to decide if there is an attack and to generate a signature through a learning process. A security policy manager (SPM) is for managing and applying a security policy to each of the plurality of security agents based on the decision of the ISE. The ISE performs a correlation analysis and a causation analysis on suspicious traffic and events and a detection message transferred from the plurality of security agents. Further, the ISE carries out a pattern analysis and generates a new detection pattern through a self-learning process.
