Kevin Mandia is the Director of Computer Forensics at Foundstone, Inc., an Internet of experience performing incident response and computer forensics. Computer Forensics is the science of obtaining, preserving, and Though Computer Forensics is often associated with Computer Security, the two are different.

In particular, there is a Defining computer forensics requires one lack of clarity regarding the distinction between more clarification. Many argue about whether data extraction and data analysis. There is also computer forensics is a science or art.

Brooks, F. The Cybercrime Lab in the 10th Cir. Throughout science. The argument is unnecessary, however.

Hence, the word "technique" is examiners from several federal agencies. The lists may be written or items below: They make sure a The Cybercrime Lab illustrates an overview clear request is in hand and that there is sufficient of the process with Figure 1. The three steps, data to attempt to answer it. Analysis, are highlighted because they are the Otherwise, they continue to set up the process.

Guide to Computer Forensics and Investigations

The first step in any forensic process is the In practice, organizations may divide these validation of all hardware and software, to ensure functions between different groups. While this is that they work properly.

There is still a debate in acceptable and sometimes necessary, it can create the forensics community about how frequently the a source of misunderstanding and frustration.

In software and equipment should be tested. Most order for different law enforcement agencies to people agree that, at a minimum, organizations effectively work together, they must communicate should validate every piece of software and clearly.

The investigative team must keep the hardware after they download it and before they entire picture in mind and be explicit when use it. They should also retest after any update, referring to specific sections.

The prosecutor and forensic examiner must When the examiner's forensic platform is decide, and communicate to each other, how ready, he or she duplicates the forensic data much of the process is to be completed at each provided in the request and verifies its integrity.

Computer Forensics : Investigations of the Future

The This process assumes law enforcement has process is potentially iterative, so they also must already obtained the data through appropriate decide how many times to repeat the process. It is legal process and created a forensic image.

A fundamentally important that everyone understand forensic image is a bit-for-bit copy of the data that whether a case only needs preparation, extraction, exists on the original media, without any additions and identification, or whether it also requires or deletions. It also assumes the forensic examiner analysis. If examiners get original evidence, they need to The three steps in the forensics process make a working copy and guard the original's discussed in this article come after examiners chain of custody.

The examiners make sure the obtain forensic data and a request, but before copy in their possession is intact and unaltered.

They typically do this by verifying a hash, or Examiners try to be explicit about every process digital fingerprint, of the evidence.

If there are any that occurs in the methodology. In certain problems, the examiners consult with the situations, however, examiners may combine steps requester about how to proceed. When examiners speak of lists such as "Relevant Data List," they After examiners verify the integrity of the do not mean to imply that the lists are physical data to be analyzed, a plan is developed to extract data.

Examiners generally theft, among other things. It is also possible for an have preliminary ideas of what to look for, based item to generate yet another search lead. An e- on the request.

They add these to a "Search Lead mail may reveal that a target was using another List," which is a running list of requested items. That would lead to a new keyword For example, the request might provide the lead search for the new nickname. The examiners "search for child pornography. As Lead List so that they would remember to they develop new leads, they add them to the list, investigate it completely.

For example, examiners For each search lead, examiners extract might find a new e-mail account the target was relevant data and mark that search lead as using. After this discovery, law enforcement may processed. They add anything extracted to a want to subpoena the contents of the new e-mail second list called an "Extracted Data List.

Examiners might also find evidence Examiners pursue all the search leads, adding indicating the target stored files on a removable results to this second list.
