20090113551 | DEVICE AND METHOD FOR INSPECTING NETWORK EQUIPMENT FOR VULNERABILITIES USING SEARCH ENGINE - Provided is a device and method for inspecting network equipment for vulnerabilities using a search engine from a remote location. The device for inspecting network equipment for vulnerabilities includes: a network structure examination module for examining the structure of a system network and generating network structure information; a control module for selecting at least one subnet for vulnerability inspection according to the network structure information; a vulnerable network equipment examination module for examining at least one piece of target network equipment for vulnerability inspection in the at least one selected subnet using a search engine; a vulnerability inspection module for inspecting the target network equipment for vulnerabilities; and an inspection result display module for outputting inspection results received from the vulnerability inspection module. The time taken to perform a vulnerability inspection and the overhead of a system subject to inspection may be reduced by selecting one of the system's subnets for inspection according to network structure information, examining the selected subnet for potentially vulnerable network equipment using a search engine, and inspecting only potentially vulnerable network equipment for vulnerabilities. | 04-30-2009 |
20090260085 | APPARATUS, SYSTEM AND METHOD FOR BLOCKING MALICIOUS CODE - Provided are an apparatus, system and method for blocking malicious code. The apparatus includes a first malicious code detector for determining whether or not a received e-mail includes malicious code, on the basis of previously stored malicious code patterns, a second malicious code detector for performing second malicious code detection on a received e-mail determined by the first malicious code detector not to include malicious code, a pattern extractor for extracting a new malicious code pattern from malicious code detected by the second malicious code detector, and a transceiver for transferring the extracted new malicious code pattern to a pattern providing server. According to the apparatus, system and method, when one terminal detects a new malicious code pattern, a pattern providing server rapidly provides the new malicious code pattern to other terminals, and thus it is possible to rapidly and flexibly cope with the spread of malicious codes having new patterns | 10-15-2009 |
20130116572 | METHOD AND APPARATUS FOR MEASURING 3-DIMENSIONAL OBJECT SHAPE BASED ON SHADOWS - An apparatus measures a 3-Dimensional (3D) shape of an object. The apparatus includes a light emitting unit and a light receiving unit that are arranged to face each other with the object disposed in a space defined therebetween, wherein the light transmitting unit being arranged to scan the object, and the light receiving unit being arranged to sense a shadow of the scanned object formed thereon. The apparatus includes a rotation unit arranged to rotate the light emitting unit and the light receiving unit about a same rotational axis by a preset rotation angle until the rotation is fully made by a desired target angle and a shape restoration unit configured to measure a 3D shape of the object using shadows that are obtained for each preset rotation angle. | 05-09-2013 |
20130219498 | MOBILE TERMINAL HAVING SECURITY DIAGNOSIS FUNCTIONALITY AND METHOD OF MAKING DIAGNOSIS ON SECURITY OF MOBILE TERMINAL - A mobile terminal having security diagnosis functionality and a method of making a diagnosis on the security of the mobile terminal are provided. The mobile terminal includes a system check unit, an interface unit, a blacklist check unit, and a security diagnosis unit. The system check unit collects the basic information of the mobile terminal by performing a system check on the mobile terminal. The interface unit provides the basic information of the mobile terminal to a user and receives a control command from the user. The blacklist check unit checks whether at least one application installed in the mobile terminal is present in a blacklist registered on a server. The security diagnosis unit checks whether an abnormality has occurred in the corresponding application based on results of the comparison between the basic information of the mobile terminal with preset abnormality detection reference information and the control command. | 08-22-2013 |
20140047543 | APPARATUS AND METHOD FOR DETECTING HTTP BOTNET BASED ON DENSITIES OF WEB TRANSACTIONS - An apparatus and method for detecting a Hyper Text Transfer Protocol (HTTP) botnet based on the densities of transactions. The apparatus includes a collection management unit, a web transaction classification unit, and a filtering unit. The collection management unit extracts metadata from HTTP request packets collected by a traffic collection sensor. The web transaction classification unit extracts web transactions by analyzing the metadata, and generates a gray list by arranging the extracted web transactions according to the frequency of access. The filtering unit detects an HTTP botnet by filtering the gray list based on a white list and a black list. | 02-13-2014 |
