A network status display device using a traffic pattern map is provided. The device includes: a traffic feature extractor extracting a port number of a port having the maximum occupancy of micro-flows and macro-flows for each network address section and host address section with reference to traffic information collected by an external traffic information collector, calculating and storing an occupancy rate of the port; a traffic status display unit making a network traffic pattern map expressed by destination-source network addresses and a host traffic pattern map expressed by destination-source host addresses and displaying the port information stored in the traffic feature extractor on the network traffic pattern map and the host traffic pattern map; and a traffic anomaly determination unit determining whether a network status is abnormal with reference to the network traffic pattern map and the host traffic pattern map and detecting and reporting a harmful or abnormal traffic which causes the abnormal network status. The device can determine whether the anomaly deteriorating the network performance exists and can easily and quickly detect the harmful or abnormal traffic which causes the anomaly by the use of the port information of the port having the maximum occupancy of the micro-flows and the macro-flows for each network address section and each host address section.

The apparatus and method for monitoring the software module state of the embedded multitasking operating system in a system using the embedded multitasking operating system according to the invention sequentially records the state information of the software modules in the state recording range of the hardware logic, sequentially reads the state information of the software modules from the state recording range, and displays the state information so that the user can easily recognize the same. As a result, the state information of the software modules can be monitored and inspected independent from the operation of the software modules of the operating system, and thus the state of the software modules or the operating system can be inspected in any exceptional software-associated situations.

Disclosed is a method of detecting abnormal traffic at the network level using a statistical analysis and a computer-readable recording medium for recording a program that implements the method. The method includes the steps of: a) gathering local traffic data from each network device and integrating a plurality of the local traffic data to generate traffic data in a network level; b) extracting a characteristic traffic data based on the traffic data in the network level; c) comparing the characteristic traffic data with a characteristic traffic data profile resulting from statistical computations, and determining whether there is abnormal traffic in the network; and d) updating the characteristic traffic data profile using the characteristic traffic data if there is no abnormal traffic in the network, analyzing seriousness of the abnormal traffic and monitoring the abnormal traffic if there is abnormal traffic in the network.

Provided is an apparatus for detecting a network attack situation. The apparatus includes an alarm receiver receiving a plurality of alarms raised in a network to which the alarm receiver is connected, converting the alarms into predetermined alarm data, and outputting the alarm data; an alarm processor analyzing an attack situation in the network based on attributes of the alarm data and a number of times that the alarm data is generated; a memory storing basic data needed to analyze the state of the network and providing the basic data to the alarm processor; and an interface transmitting the result of the analysis by the alarm processor to an external device, receiving a predetermined critical value from the external device, which is a basis for determining the occurrence of the attack situation, and outputting the critical value to the alarm processor such that the alarm processor can store the critical value in the memory. Equal numbers of hash engines and detection engines for processing the alarms in the network to the number of data groups classified as network attack situations are formed in a line. Therefore, a network attack situation can be detected in real time based on a great number of alarms indicating intrusion detection.
