A registration device () includes an extracting unit () that extracts inner header information and outer header information of an encapsulated packet, a filter unit () that calculates a hash value of the inner header information and the outer header information as an address of a hash table in which arrival information indicating whether a first packet of a series of flow has arrived is registered for each address and causes, based on the hash table, inner header information and outer header information of the first packet of the series of flow to pass, and a registering unit () that registers the inner header information and the outer header information of the first packet, which the filter unit () has caused to pass, in a database in association with each other.

Registration system, registration method, and registration program

A feature calculation unit calculates a feature of header information of a packet. A classification unit classifies the packet as a normal packet or an abnormal packet by using the calculated feature. An adding unit adds a label indicating a tool name of a known attack tool to header information of a packet attacked using the attack tool. A learning unit learns the addition of the label by using the label and the feature calculated for the packet to which the label has been added as teacher data.

Detection device and detection method

A continuity checking apparatus generates a continuity checking packet to which a predetermined flag and user attributes are assigned and transmits the generated continuity checking packet to an edge router connected to a service that is an entrance of a service chain. Each service transmits an arrival message with respect to the continuity checking packet to the continuity checking apparatus upon reception of the continuity checking packet to which the predetermined flag is assigned. In addition, each service transfers the continuity checking packet to a next service device of the service chain on the basis of the user attributes assigned to the received continuity checking packet. The continuity checking apparatus identifies a path representing service devices through which the continuity checking packet passes on the basis of the arrival message transmitted from each service, and determines whether the identified path is the same as a path of the service chain that is a continuity checking target.

Communication system and method of verifying continuity

The controller () acquires information about the band of the flow within the tunnel and the band of each flow after policing or shaping, calculates the ratio of the traffic volume after policing or shaping to the traffic volume before policing or shaping by using the acquired information about the band, and estimates the traffic volume of the flow to be monitored within the tunnel by using the calculated ratio and the band of each flow after policing or shaping.

Estimation method, estimation device, and estimation program

A collection device () collects traffic from a core network (N) connected to a plurality of operator networks (N). Further, an analysis device has a plurality of functions of analyzing traffic. Further, a setting device sets a scenario that designates at least one of the plurality of functions. Further, a pre-processing device converts the traffic collected by the collection device () to traffic of a format suitable for the function designated by the scenario. Further, a distribution device distributes the traffic converted by the pre-processing device to a designated function.

Analysis system and analysis method

A handling apparatus () handles a server attack taking place on a network (Na) or handles a server attack as requested by a security system provided on another network. In accordance with a determination that it is not possible to handle the server attack by the handling apparatus (), the control determination apparatus () makes a request to another security system (Sb) capable of handling the server attack to handle the server attack. A centralized control apparatus () determines whether the server attack taking place on the network (Na) can be handled on another network.

Control system, control determination device, and control method

Disclosed is a thin film forming apparatus which is a plasma discharge processing apparatus for performing a plasma discharge processing on the surface of a continuously transported base at or near atmospheric pressure, wherein a reverse flow of the processing gas is prevented and thus a thin film having good quality is formed by a uniform gas flow. The thin film forming apparatus is characterized by having an auxiliary gas discharge means for discharging an auxiliary gas for preventing a reverse flow of the processing gas. Also disclosed are a thin film forming method, and a thin film.
