摘要： A server receives a first echo request message which complies with an Internet control message protocol, extracts filtering information from hear information of the received first echo request message, and when a second echo request message which complies with the Internet control message protocol is received, compares header information of the received second echo request message and the extracted filtering information so as to determine whether to block an attacking packet for the received second echo request message. According to the present invention, the server blocks the attacking packet using the Internet control message protocol, thereby blocking a denial-of-service attack.

摘要： There are provided a method and apparatus for defending a Distributed Denial-of-Service (DDoS) attack through abnormally terminated sessions. The DDoS attack defending apparatus includes: a session tracing unit configured to parse collected packets, to extract header information from the collected packets, to trace one or more abnormally terminated sessions corresponding to one of pre-defined abnormally terminated session cases, based on the header information, and then to count the number of the abnormally terminated sessions; and an attack detector configured to compare the number of the abnormally terminated sessions to a predetermined threshold value, and to determine whether a DDoS attack has occurred, according to the results of the comparison. Therefore, it is possible to significantly reduce a false-positive rate of detection of a DDoS attack and the amount of computation for detection of a DDoS attack.

摘要： 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 hash key generator hashes a parameter extracted from the received packet and generates a hash pointer of the session table corresponding to the packet. 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.

摘要： Disclosed herein is a method for blocking a Denial-of-Service (DoS) attack. A server extracts a plurality of suspicious packets including data, length of which is equal to or greater than a preset length, from a plurality of received packets. The server determines a packet, which includes data composed of characters or character strings identical to each other, among the plurality of suspicious packets, to be an attack packet. The server blocks a packet corresponding to the attack packet. Accordingly, the present invention can block a DoS attack based on UDP flooding.
摘要翻译：本文公开了一种用于阻止拒绝服务（DoS）攻击的方法。服务器从多个接收到的分组提取包括其长度等于或大于预设长度的数据的多个可疑分组。在多个可疑包中，服务器确定包括由彼此相同的字符或字符串组成的数据的分组，作为攻击包。服务器阻止与攻击报文相对应的报文。因此，本发明可以阻止基于UDP泛洪的DoS攻击。
