Abstract: An alert transmission apparatus for a policy-based intrusion detection and response has a central policy server (CPS) and an intrusion detection and response system (IDRS). In the CPS, a policy management tool generates security policy information and then stores the generated security policy information in a policy repository. A COPS-IDR server sends the information to the IDRS and an IDMEF-XML-type alert transmission message to a high-level module. An IDMEF-XML message parsing and translation module stores a parsed and translated IDMEF-XML-type alert transmission message in an alert DB or provides the message to an alert viewer. In the IDRS, a COPS-IDR client generates the IDMEF-XML-type alert transmission message and provides the message to the CPS. An intrusion detection module detects an intrusion. An intrusion response module responds to the intrusion. An IDMEF-XML message building module generates an IDMEF-XML alert message and provides the message to the COPS-IDR client.

Therefore, a regular granular structure can be formed in the recording layer without a process such as etching of the recording layer, so that the recording density of the magnetic recording medium can be largely improved.

Abstract: A real-time stateful packet inspection method and apparatus is provided, which uses a session table processing method that can efficiently generate state information. In the apparatus, a session table stores session data of a packet received from an external network.

A session detection module searches the session table for a session corresponding to the received packet. A session management module performs management of the session table such as addition, deletion, and change of sessions of the session table. A packet inspection module generates state information corresponding to the received packet from both directionality information of the packet and entry header information of the packet stored in the session table and then inspects the packet based on the generated state information.

Abstract: A method for recognizing a receiving node by a transmitting node which transmits multicast data, and transmitting the multicast data to the receiving node in a wireless network including nodes that transmit and receive multicast data in at least one time slot. The transmitting node transmits a multicast solicit message indicating generation of the multicast data, and recognizes the receiving node by receiving from the receiving node a multicast join message containing information relating to the receiving node. The transmitting node selects at least one free time slot to reserve a time slot in which the generated multicast data is transmitted. The transmitting node transmits a multicast reservation request message containing information relating to the selected free time slot to the receiving node. The receiving node transmits a reservation response message to the transmitting node when the free time slot does not collide with reserved time slots of other nodes.

Abstract: A method for reserving non-colliding time slots by a node in a wireless network and a method for avoiding colliding time slots are provided. A transmitting node or a receiving node broadcasts information relating to its reserved time slot to neighbor nodes. A node in the wireless network recognizes information relating to time slots of neighbor nodes and of neighbor's neighbor nodes. Thus, when reserving a time slot for data transmission, time slot collision can be prevented by selecting the time slot based on the recognized information. If collision occurs in the reserved time slot and the node wants to cancel the reservation, the node informs a correspondent node of the reservation cancellation. Accordingly, the collision can be promptly resolved.
