摘要： A method and apparatus for digital forensics are provided. The apparatus for digital forensics includes a page file extractor for extracting a page file stored in a target storage medium, a stored-page feature extractor for extracting features of pages stored in the extracted page file, a page classifier for comparing the extracted features of the pages with at least one predetermined classification criterion and classifying the pages according to the comparison results, and a digital forensics unit for performing digital forensics according to the classified pages. According to the method and apparatus, it is possible to perform digital forensics using only information of a page file.

摘要： 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.

摘要： Provided are a fuzzing system and method of a distributed computing environment (DCE) remote procedure call (RPC) object. The fuzzing system includes a file manager, a random data generator, a RPC packet, and a packet injector. The file manager obtains necessary information by parsing and analyzing an idl file for a target object for fuzzing and a file having information about a Named Pipe file. The random data generator generates a random value using a system clock as a factor. The RPC packet creator embodies protocols used for RPC communication by functions and generating a RPC packet for RPC communication. The packet injector inserts the necessary information and the random value into the generated RPC packet and transmits the generated RPC packet to the target object for fuzzing.
摘要翻译：提供了分布式计算环境（DCE）远程过程调用（RPC）对象的模糊系统和方法。模糊系统包括文件管理器，随机数据生成器，RPC分组和分组注入器。文件管理器通过解析和分析用于模糊的目标对象的idl文件和具有关于命名管道文件的信息的文件来获得必要的信息。随机数据生成器使用系统时钟作为因子生成随机值。 RPC分组创建者体现用于通过功能进行RPC通信的协议，并生成用于RPC通信的RPC分组。分组进样器将必要的信息和随机值插入生成的RPC分组中，并将生成的RPC分组发送到目标对象进行模糊。

摘要： Provided are a system and method for detecting a malicious script. The system includes a script decomposition module for decomposing a web page into scripts, a static analysis module for statically analyzing the decomposed scripts in the form of a document file, a dynamic analysis module for dynamically executing and analyzing the decomposed scripts, and a comparison module for comparing an analysis result of the static analysis module and an analysis result of the dynamic analysis module to determine whether the decomposed scripts are malicious scripts. The system and method can recognize a hidden dangerous hypertext markup language (HTML) tag irrespective of an obfuscation technique for hiding a malicious script in a web page and thus can cope with an unknown obfuscation technique.
