操作系统实验室虚拟化方案研究

本文从实际应用出发,分析了操作系统实验室的需求特点与当前应用状况,从硬件配置、软件选择、安装、部署与管理等多方面分析了桌面级虚拟化方案和服务器级虚拟化方案。经过对比研究,指出桌面级虚拟化方案更适合操作系统实验室环境。本文还从实验室管理的角度分析了还原卡在部署与管理方面的限制与不足,建议引入具有行业标准的自动化部署工具与方案,并使用成熟的目录服务进行日常的实验室管理,以实现用户数据安全与隔离,实验状态数据保存等系统实验室迫切且需要的功能。     

由鲍德里亚的仿真理论看威廉·吉布森的赛博朋克科幻小说

威廉·吉布森开创了美国赛博朋克科幻小说流派，其作品所描述的近未来世界表现了后现代科技社会真实虚化的危机，自然、人体、意识均可以被技术化、人工化、虚拟化，本文借助鲍德里亚的仿真理论对其作品所反映的这一现象进行剖析。     

OpenLV: Empowering investigators and first-responders in the digital forensics process

The continuing decline in the cost-per-megabyte of hard disk storage has inevitably led to a ballooning volume of data that needs to be reviewed in digital investigations. The result: case backlogs that commonly stretch for months at forensic labs, and per-case processing that occupies days or weeks of analytical effort. Yet speed is critical in situations where delay may render the evidence useless or endanger personal safety, such as when a suspect may flee, a victim is at risk, criminal tactics or control infrastructure may change, etc. In these and other cases, investigators need tools to enable quick triage of computer evidence in order to answer urgent questions, maintain the pace of an investigation and assess the likelihood of acquiring pertinent information from the device.This paper details the design and application of a tool, OpenLV, that not only meets the needs for speedy initial triage, but also can facilitate the review of digital evidence at later stages of investigation. With OpenLV, an investigator can quickly and safely interact with collected evidence, much as if they had sat down at the computer at the time the evidence was collected. Since OpenLV works without modifying the evidence, its use in triage does not preclude subsequent, in-depth forensic analysis. Unlike many popular forensics tools, OpenLV requires little training and facilitates a unprecedented level of interaction with the evidence.
