20110040410APPARATUS AND METHOD CONTROLLING LEGGED MOBILE ROBOT - Disclosed is an apparatus and method adjusting motion of each joint of a robot to compensate for friction force of each joint such that the sole of the foot of the robot clings to the ground. The motion of each joint is adjusted as if gravity acts on each joint of the robot in a direction opposite to gravity and the robot is held in an erect state. Therefore, the robot can stand while keeping its balance without falling.02-17-2011

20100162350SECURITY SYSTEM OF MANAGING IRC AND HTTP BOTNETS, AND METHOD THEREFOR - The present invention relates to a security system of managing IRC and HTTP botnets and a method therefor. More specifically, the present invention relates to a system and a method that detects a botnet in an Internet service provider network to store information related to the detected botnet in a database and performs security management of IRC and HTTP botnets, including a botnet management security management (BMSM) system, configured to visualize the information related to the detected botnet and establish an against policy related to the detected botnet. Accordingly, the present invention provides a security system of managing IRC and HTTP botnets that can efficiently performs the security management of IRC and HTTP botnets by using the BMSM system06-24-2010
20100169973System and Method For Detecting Unknown Malicious Code By Analyzing Kernel Based System Actions - There is provided a system and method for detecting unknown malicious code by analyzing kernel based system actions. More particularly, the system and method provides an advantage of actively countering unknown malicious code or viruses by monitoring kernel based system events in real time, organizing action data based on the collected event data, determining whether the action data corresponds to predetermined malicious actions, backtracking a subject of a malicious action when the action data is determined to correspond to the malicious action, and processing the malicious action.07-01-2010
20110153811SYSTEM AND METHOD FOR MODELING ACTIVITY PATTERNS OF NETWORK TRAFFIC TO DETECT BOTNETS - 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.06-23-2011
20110154489SYSTEM FOR ANALYZING MALICIOUS BOTNET ACTIVITY IN REAL TIME - A system for analyzing malicious botnet activity in real time is disclosed. This system may include: a control server configured to generate botnet activity information relating to a type of malicious botnet activity, and transmit the botnet activity information to the outside, after receiving bot occurrence information from the outside;06-23-2011
20110154492MALICIOUS TRAFFIC ISOLATION SYSTEM AND METHOD USING BOTNET INFORMATION - 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.06-23-2011
