This information can be relevant to civil and criminal investigations. Computer forensics involves the collection, analysis, and reporting of digital data to use this information in an investigation.
Computer forensics experts must understand how to extract this information in a way that makes it admissible as evidence in court.
Computer forensics has a variety of applications. Law enforcement uses computer forensics to examine computers when investigating crimes such as murder, kidnapping, and fraud. Investigators might examine emails, Internet browsing history, and files located on a computer to gather evidence. Companies also use computer forensics to investigate cases involving inappropriate use of company computers, system and network security, and internal issues such as intellectual property theft.
For evidence to be admissible, investigators must follow guidelines carefully. No actions performed by investigators can change the data in any way. The investigator extracting data must have training to ensure competence. This professional must also be able to explain the process and the reasons for it in court, if applicable. Investigators must be able to document the processes performed.
A third party must be able to examine this documentation and follow along to arrive at the same end result. One person on the forensics team must have the ultimate responsibility for the process, ensuring that the actions of all team members were in compliance with the law. A computer forensics examination includes six separate stages. The readiness stage involves training, testing, and verification of any applicable computer software or equipment. Review of laws and potential issues as well as communication with clients and preparing a computer system for examination are also included in the readiness stage.
The evaluation stage involves receiving and clarifying instructions to ensure understanding. Evaluation also involves assessing potential risks involved with the examination. During the collection stage, experts extract and examine information from computers. This process might occur on site or in a forensic laboratory. Members of a team may also collect physical evidence if any is found, placing items into labeled plastic bags.
The next stage involves analysis of the evidence. Team members must analyze, record, and repeat their analysis to ensure accuracy. During presentation, team members share their findings and address specifics connected to the purpose of the examination. The report created must be prepared in a way that the people reading it will understand the information. Often, these people will have limited technical knowledge. Elaboration and explanation by team members may be necessary to help people understand the findings.
The final review stage involves applying the information gathered. For example, a company engaging in computer forensics might use the information collected to make policy changes or to institute stronger network security. Computer forensics teams might encounter a number of issues.
Encrypted data on a computer might be impossible to access without a password. In this situation, a team may need to use special acquisition techniques. Adequate processing power may be necessary to examine large storage devices for computers. With new developments in computer software and hardware, computer forensics must continually evolve to match new technology. Testing and experimentation may be necessary in these situations. Some people may utilize anti-forensics tactics to keep investigators from accessing data.
Encryption, overwriting data, modifying metadata, and disguising files are examples of anti-forensics tactics. Legal issues may also arise. A computer owner may devise a legal defense designed to create a distraction from the findings. Various administrative issues could also affect how groups accept findings from a computer forensic investigation.

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.
