Abstract:
PURPOSE: A network-based remote forensic system is provided to easily use evidence data with the accumulation of collected evidence data. CONSTITUTION: One or more remote terminals(240) interlink an evidence device(110) in a remote place. The remote terminal performs forensic for the evidence device with a virtual forensic tool. An investigation center system(200) is connected through a wide area network to the remote terminal. The investigation center system offers the virtual forensic tool. The investigation center system processes the requirement of the remote terminal.
Abstract:
PURPOSE: A management system of internet security platform performing IPsec(Internet Protocol security) communication and a management method thereof are provided to control security service, by managing an internet security service and storing interconnection of security service providing related modules in a network as MIB(Management Information Bases) and providing top view as to security service to a security manager. CONSTITUTION: According to the apparatus for managing a host comprising an IPsec engine and security policy and key exchange and a key management server in an internet security platform performing IPsec communication, a web browser interface part(110) provides web access interface environment to access through a web remotely. A web server part(120) enables a user accessing through the web browser interface part to manage the host. A JSP part(130) performs user authentication as to a user accessing through the web server part. A management server part(150) manages the operation of the internet platform according to a management request of the user. A management tool part(160) performs a corresponding management operation as to the internet platform according to the management request by being controlled by the management server part. And an agent part(170) receives and stores information for each management from a host to manage, and performs a corresponding management command using the stored information when the management tool part receives the corresponding management operation command.

Abstract:
In the extraction and analysis of a forensic evidence document of a digital forensic system using a smart device, the present invention provides the convenience of an investigation by collecting and analyzing digital evidences in a crime scene in real time by extracting document information by directly performing the forensic analysis of the evidence document below a reference capacity by dividing a file size in the smart device or performing a forensic analysis by transmitting the evidence document exceeding the reference capacity to a remote server.
Abstract:
PURPOSE: A forensic index method using distribution processing and a device thereof are provided to increase or decrease used resources corresponding to the amount of analyzed data, thereby implementing performance adjustment. CONSTITUTION: A division object data management unit(100) generates division object data by dividing indexing object data corresponding to division setting. A division index data generation unit(200) assigns the division object data to data processing units corresponding to the division setting. The division index data generation unit extracts an index by filtering the division object data. The division index data generation unit generates division index data including the index. An index database management unit(300) generates index database by merging the division index data. [Reference numerals] (100) Division object data management unit; (200) Division index data generation unit; (210,CC) Distribution storage unit; (230,DD) Filtering unit; (250,EE) Index extraction unit; (270,FF) Division index data generation unit; (300) Index database management unit; (AA) First data processing unit; (BB) n-th data processing unit
Abstract:
PURPOSE: A method for analyzing and validating data which are collected through the internet and a system thereof are provided to generate an index database for a webpage that a user visits and web mail content and search online data in real time. CONSTITUTION: An online data forensic server(210) collects and analyzes usage history information from a target device for data collection. The online data forensic server downloads and collects data in the Internet based on the usage history information and requests and receives a timing check token for the collected data. A timing check token issuing server(220) issues a timing check token for the collected data and provides the timing check token to the online data forensic server.
Abstract:
An intrusion blocking policy enforcement apparatus in a router hardware platform and a method thereof are provided to decide whether it is time for newly arranging and enforcing plural intrusion blocking policies, stored in a policy DB, according to priority, therefore fast priority processing and policy enforcement are available. A policy DB(120) stores at least more than one intrusion blocking policy together with related information. A policy server(110) adds or deletes the intrusion blocking policies to or from the policy DB(120). A time controller(130) determines whether to enforce the intrusion blocking policies according to priority by referring to the related information. An intrusion blocking unit(140) blocks intrusion by enforcing the intrusion blocking policies corresponding to determination results of the time controller(130), to data processed by a router hardware platform.
