课程名称：计算机取证基础 课程概述：计算机取证是一门数字取证科学的分支，涉及在计算机和数字存储介质中发现的证据。计算机取证的目标是以法医学上可靠的方式检查数字媒体，以识别、保存、恢复、分析并呈现有关数字信息的事实和观点。尽管计算机取证通常与各种计算机犯罪的调查相关联，但在民事诉讼中也可能会使用该技术。该学科涉及与数据恢复类似的技术和原则，但附加了旨在创建法律审计痕迹的指南和实践。 计算机取证调查中的证据通常遵循其他数字证据的相同指南和实践，并已在多个高知名度案件中使用，被广泛接受为在美国和欧洲法院系统中可靠的证据。自上世纪80年代以来，个人电脑的普及促进了其在犯罪活动中的使用（例如，帮助实施欺诈）。与此同时，一些新型“计算机犯罪”被认可，比如黑客行为。计算机取证的学科在此时开始出现，作为一种恢复和调查数字证据以用于司法的手段。自那时起，计算机犯罪和计算机相关犯罪持续增长，2002年至2003年之间增长了67%。如今，计算机取证用于调查各种犯罪，如儿童色情、诈骗、间谍行为、网络骚扰、谋杀和强奸。该学科还作为信息收集的形式出现在民事诉讼中（例如，电子发现）。 计算机取证调查通常遵循标准的数字取证过程或阶段，包括获取、检查、分析和报告。调查是在静态数据（即获取的图像）上进行，而不是在“实时”系统中进行。这与早期的取证实践有所不同，因为缺乏专业工具导致调查人员常常在实时数据上工作。
Learn the fundamentals of Computer forensics (also known as computer forensic science) is a branch of digital forensic science pertaining to evidence found in computers and digital storage media. The goal of computer forensics is to examine digital media in a forensically sound manner with the aim of identifying, preserving, recovering, analyzing and presenting facts and opinions about the digital information.Although it is most often associated with the investigation of a wide variety of computer crime, computer forensics may also be used in civil proceedings. The discipline involves similar techniques and principles to data recovery, but with additional guidelines and practices designed to create a legal audit trail.Evidence from computer forensics investigations is usually subjected to the same guidelines and practices of other digital evidence. It has been used in a number of high-profile cases and is becoming widely accepted as reliable within U.S. and European court systems.In the early 1980s personal computers became more accessible to consumers, leading to their increased use in criminal activity (for example, to help commit fraud). At the same time, several new "computer crimes" were recognized (such as cracking). The discipline of computer forensics emerged during this time as a method to recover and investigate digital evidence for use in court. Since then computer crime and computer related crime has grown, and has jumped 67% between 2002 and 2003. Today it is used to investigate a wide variety of crime, including child pornography, fraud, espionage, cyberstalking, murder and rape. The discipline also features in civil proceedings as a form of information gathering (for example, Electronic discovery)Computer forensic investigations usually follow the standard digital forensic process or phases which are acquisition, examination, analysis and reporting. Investigations are performed on static data (i.e. acquired images) rather than "live" systems. This is a change from early forensic practices where a lack of specialist tools led to investigators commonly working on live data.
