摘要： The invention relates to a system and method that can detect botnets by classifying the communication activities for each client according to destination or based on similarity between the groups of collected traffic. According to certain aspects of the invention, the communication activities for each client can be classified to model network activity by differentiating the protocols of the collected network traffic based on destination and patterning the subgroups for the respective protocols. Those servers that are estimated to be C&C servers can be classified into download and upload, spam servers and command control servers, within a botnet group detected by modeling network activity, i.e. analyzing network-based activity patterns. Also, botnet groups can be detected by way of a group information management function, for generating an activity pattern-based group matrix based on group data, and a mutual similarity analysis, performed on groups suspected to be botnets from the group information.

摘要： The present invention relates to a malicious traffic isolation system and method using botnet information, and more particularly, to a malicious traffic isolation system and method using botnet information, in which traffics for a set of clients having the same destination are routed to the isolation system based on a destination IP/Port, and botnet traffics are isolated using botnet information based on similarity among groups of the routed and flowed in traffics. The present invention may provide a malicious traffic isolation method using botnet information, which can accommodate traffics received from a PC or a C&C server infected with a bot into a quarantine area, isolate traffics generated by normal users from traffics transmitted from malicious bots, and block the malicious traffics. In addition, the present invention may provide a malicious traffic isolation method using botnet information, which can provide a function of mitigating DDoS attacks of a botnet.

摘要： Disclosed is a system for lawful interception using a trusted third party in secure VoIP communication. A VoIP transmit terminal generates a secure packet using a master key received from a trusted third party and then communicates with a VoIP receive terminal. A collection device having received a lawful interception instruction from a key recovering system collects and transmits the secure packet to the key recovering system. The key recovering system decrypts the secure packet using the master key received from the trusted third party and provides the decrypted secure packet to a lawful interception requester or provides the master key received from the trusted third party and the secure packet to the lawful interception requester. It is possible to provide the perfect lawful interception in the secure VoIP communication environment, and to guarantee a perfect forward secrecy since the master key is changed for each call.
