Analysis and interpretation Documentation and presentation The Cybercrime Lab illustrates an overview of the process with Figure 1.

Figure 1 In practice, organizations may divide these functions between different groups. While this is acceptable and sometimes necessary, it can create a source of misunderstanding and frustration. In order for different law enforcement agencies to effectively work together, they must communicate clearly.

The investigative team must keep the entire picture in mind and be explicit when referring to specific sections. The prosecutor and forensic examiner must decide, and communicate to each other, how much of the process is to be completed at each stage of an investigation or prosecution.

The process is potentially iterative, so they also must decide how many times to repeat the process. It is fundamentally important that everyone understand whether a case only needs preparation, extraction, and identification, or whether it also requires analysis.

The three steps in the forensics process discussed in this article come after examiners obtain forensic data and a request, but before reporting and case-level analysis is undertaken.

Examiners try to be explicit about every process that occurs in the methodology. In certain situations, however, examiners may combine steps or condense parts of the process. When examiners speak of lists such as "Relevant Data List," they do not mean to imply that the lists are physical documents.

The lists may be written or items committed to memory. Finally, keep in mind that examiners often repeat this entire process, since a finding or conclusion may indicate a new lead to be studied. They make sure a clear request is in hand and that there is sufficient data to attempt to answer it.

If anything is missing, they coordinate with the requester. Otherwise, they continue to set up the process. The first step in any forensic process is the validation of all hardware and software, to ensure that they work properly.

There is still a debate in the forensics community about how frequently the software and equipment should be tested. Most people agree that, at a minimum, organizations should validate every piece of software and hardware after they purchase it and before they use it.

They should also retest after any update, patch, or reconfiguration. When the examiner's forensic platform is ready, he or she duplicates the forensic data provided in the request and verifies its integrity. This process assumes law enforcement has already obtained the data through appropriate legal process and created a forensic image.

A forensic image is a bit-for-bit copy of the data that exists on the original media, without any additions or deletions. It also assumes the forensic examiner has received a working copy of the seized data. If examiners get original evidence, they need to make a working copy and guard the original's chain of custody.

The examiners make sure the copy in their possession is intact and unaltered. They typically do this by verifying a hash, or digital fingerprint, of the evidence.

If there are any problems, the examiners consult with the requester about how to proceed. After examiners verify the integrity of the data to be analyzed, a plan is developed to extract data.

They organize and refine the forensic request into questions they understand and can answer. The forensic tools that enable them to answer these questions are selected.

Examiners generally have preliminary ideas of what to look for, based on the request. They add these to a "Search Lead List," which is a running list of requested items. For example, the request might provide the lead "search for child pornography. As they develop new leads, they add them to the list, and as they exhaust leads, they mark them "processed" or "done.

They add anything extracted to a second list called an "Extracted Data List. Then they move to the next phase of the methodology, identification. Identification Examiners repeat the process of identification for each item on the Extracted Data List.According to the Computer Emergency and Response Team at Carnegie-Mellon University, the number of computer intrusions in the United States increased percent between and During the same time period, the number of network sites affected by computer crimes increased by percent.

The Department of Justice's Computer Crime . Computer Crime. Computer crime describes a very broad category of offenses.
