DIDS based on hybrid detection

Information security is one of the priorities in the context of communication technologies. The work is focused on intrusion detection in high-speed computer networks. Request-transition diagrams method describing the time-dependent phenomena provides an effective method to announce passages preceding the existence of disturbance. Modified hybrid detection reduces the responsiveness of the system and method provides real-time tracking. In a correct state of the system is used only one method of detection, which is provided in real-time. Definition of indefinite field brings extension to dual detection methods to ensure accuracy and recovery of erroneous detections. Distributed detection methods based on descriptive rules accelerate the detection process.
