Abstract: Provided are a method and apparatus for extracting text from an Internet mail attachment file. The apparatus includes a mail display unit for displaying Internet mail and an attachment file received from outside, an attachment file storage for storing the attachment file, a text extraction engine for extracting a text code included in the attachment file, and an attachment file text extractor for extracting text included in the attachment file using the text extraction engine.

Abstract: Provided is a method and apparatus for analyzing an exploit code included in a nonexecutable file using a target program with vulnerability in a virtual environment. The method includes the steps of: loading a nonexecutable file including the exploit code by a target program, the target program being executed in a virtual environment and includes vulnerability; analyzing a register value of the target program and determining if the register value of the target program indicates a normal code region; storing log information on operation of the target program when the register value indicates a region other than the normal code region; and extracting and analyzing the exploit code included in the nonexecutable file based on the stored log information. In this method, the exploit code is analyzed in the virtual environment, thereby preventing damage caused by execution of the exploit code.

Abstract: A system and method for managing a network by value-based estimation is provided. A network device requesting communication is defined as an active point and a network device receiving a request for communication is defined as a passive point. A value of a network device is determined according to the number of active points connected to the corresponding network device, and a value of a network device that is in a path of communication between network devices is determined based on a value of a network device passing through the corresponding network device. When a policy for changing a network environment is transferred in a state where the values of the network devices have been estimated, a policy conflict test is performed on the basis of the estimated values of the network devices, thereby determining application of the policy in due consideration of the values and significance of the network devices.

Abstract: A system and method for analyzing a file format to perform a software security test are provided. The system includes a file scanner for monitoring a program that loads an unknown file on a memory and parsing function parameters of the loaded file, and a file analyzer for receiving the parsing data from the file scanner and extracting a field location and a data type of the unknown file format.
