20140115663 | METHOD FOR DETECTING UNAUTHORIZED ACCESS AND NETWORK MONITORING APPARATUS - A method for detecting unauthorized access is executed by a network monitoring apparatus connected to a network in which packets are transmitted between a plurality of information processing apparatuses. The method includes obtaining, by the network monitoring apparatus, packets regarding at least one access performed from a first information processing apparatus to a second information processing apparatus. The method includes selecting at least one condition from among predefined at least two conditions. The selection is performed according to a combination between the first information processing apparatus as an access source and the second information processing apparatus as an access destination. The method includes determining whether each of the obtained packets satisfies the selected at least one condition. The method includes determining a possibility that unauthorized access has been performed on the second information processing apparatus, based on a number of conditions determined to be satisfied. | 04-24-2014 |
20140115705 | METHOD FOR DETECTING ILLEGAL CONNECTION AND NETWORK MONITORING APPARATUS - A network monitoring apparatus acquires a first packet transmitted from a first information processing apparatus to a second information processing apparatus. The network monitoring apparatus acquires a second packet transmitted from the second information processing apparatus to the first information processing apparatus. The second packet is transmitted within a predetermined time period since the transmission of the first packet. The network monitoring apparatus determines whether the first packet is a packet according to a protocol used for transmitting a file and the second packet is related to a connection established from the second information processing apparatus to the first information processing apparatus. The network monitoring apparatus outputs result information depending on a result of the determination. | 04-24-2014 |
20140297699 | APPARATUS AND METHOD FOR MONITORING COMMUNICATION - An apparatus acquires a packet transmitted according to a protocol employing block access, from a communication network, and determines which one of a system attribution block storing stores file system attribution data, a file attribution block storing file attribution data, and a file name block storing file name data the packet is related to. The apparatus calculates a block number of the file attribution block, based on addresses provided to the system and file attribution blocks, when the packet is determined to be related to the file attribution block. The apparatus calculates an identification number of each piece of the file attribution data, based on the system attribution data and the calculated block number, and associates file attribution data stored in the file attribution block with file name data stored in the file name block, based on the calculated identification numbers and identification numbers provided to the file name data. | 10-02-2014 |

20150195294 | NETWORK MONITORING APPARATUS AND METHOD - When obtained communication data corresponds to an external communication from the outside of the network to the inside, external communication data is stored. When the obtained communication data corresponds to a service start, external communication data associated with the service start is extracted, and service start data is stored in correlation with the extracted external communication data. When the obtained communication data corresponds to an operation end, operation end data is stored. When the obtained communication data corresponds to a communication from the inside to the outside of the network, operation end data associated with the obtained communication data is extracted. Then, it is determined that a condition is satisfied that external communication data associated with the obtained communication data is stored in correlation with the service start data associated with the extracted operation end data. When the condition is satisfied, an attack for the system is detected. | 07-09-2015 |
