Network-attached storage (NAS) is a system that uses a redundant array of disks (RAID) to create virtual disks comprising multiple disks and provide network services such as FTP, SSH, and WebDAV. Using these services, the NAS's virtual disks store data about individuals or groups, making them a critical analysis target for digital forensics. Well-known storage manufacturers like Seagate, Synology, and NETGEAR use Linux-based software RAID, and they usually support Berkeley RAID (e.g., RAID 0, 1, 5, 6, and 10) as well as self-developed hybrid RAID. Those manufacturers have published data on the introduction and features of hybrid RAID, but there is not enough information to reassemble RAID from a digital forensic perspective. Besides, digital forensic tools (such as EnCase, FTK, X-ways, and RAID Reconstructor) do not support automatic RAID reassembly for hybrid RAID, so research on hybrid RAID reassembly methods is necessary. This paper analyzes the disk array composed of hybrid RAID and explains the layout of disk array, partition layout in hybrid RAID, and hybrid RAID configuration strategy. Furthermore, it suggests parameters that are required for RAID reassembly and then propose a hybrid RAID reassembly procedure using them. Finally, we propose a proof-of-concept tool (Hybrid RAID Reconstructor) that identifies hybrid RAID from disk array and parse RAID parameters. 相似文献

The U.S. health-care costs have increased at a rapid rate over the last several decades. How much responsibility the government should bear with the increase in health-care costs is one of the main questions that lack consensus among the American people. Utilizing the 2016 General Social Survey data, this study shows that over two-thirds of Americans want to see more or much more spending on health care by the government. An ordered logit regression model shows that political trust and ideology are significant correlates in predicting attitudes toward government spending on health care. The policy implications of the findings are discussed in the “Conclusion” section. 相似文献

This article addresses a profoundly curious question of why Korea and Japan conflict with each other despite deepening ties and growing transactions. In contrast to the existing explanations, this article makes three analytical innovations. First, for inducing cooperation between Korea and Japan, what matters is convergence/divergence of external threat perception, not the magnitude of threat. Second, history is not a constant but a variable. Historical contentions can be escalated or deescalated depending on political situations. Third, the role of the US in managing Korea–Japan relations is important but not determinant. The style of US engagement in East Asia serves as an intervening variable for conflict management. This article suggests that frictions are highest when historical contentions are escalated and external threat perception diverges. On the other hand, cooperation potential is highest when historical contentions are deescalated and threat perception converges. 相似文献

An accurate and simple method was developed to determine the level of toluene in urine and blood quantitatively by using the gas chromatography/mass spectrometry (GC/MS) with headspace--solid phase microextraction (HS-SPME) technique. An assembly of SPME with a replaceable extraction fiber, coated with 100 microm polydimethylsiloxane, was used. The detection limit of toluene in blood and urine with HS-SPME technique was 10 times higher than that with headspace (HS) technique. To compare the HS-SPME with HS technique for the determination of toluene in biological fluids, blood and urine samples from glue sniffers were analyzed by both methods. The level of toluene by the two techniques was highly correlated: the correlation coefficient (r2) between the two sets of values were 0.98 and 0.96 in urine and blood, respectively. 相似文献
