A Loud Whisper – Understanding Computer Forensics Reports

Posted by admin2 | Computer Forensics |

In the field of computer forensics, as in the field of law, procedures in civil cases differ somewhat from those in criminal cases. The collection of data and presentation of evidence may be held to different standards, the process of data collection and imaging can be quite different, and the consequences of the case may have very different impacts.

Computer forensics reports are prepared by computer forensics investigators. They gather the necessary information, analyze them and then draft out the final computer forensics reports. As good as they are, computer criminals oftentimes leave behind clues which aid the investigators to track down the root cause of their crime.

Even when the files have been deleted from the specific location in the computer, the original data is not at all erased from the entire computer system. With certain techniques, tools, and skills that the investigators are equipped with, the analysis of the fraudulent act or crime can be made with such accuracy.

Where does the computer forensic report information come from?

There are four main areas where the investigators gather their evidence from. There are other areas which are looked into but the following are the most commonly looked areas.

In order to detect illegal activities, the computer forensics analysts use the sophisticated tools and fully equipped laboratories to conduct thorough and accurate investigations.

The Deleted Files:
When data is deleted, it is put in the trash bin. The computer forensic expert will look in the bin to see what is in it.

The tougher part is the deleted files that have also been deleted from the trash bin. These will require special software in order to restore them.

By contrast, in a civil case, there tends to be a lot of negotiation over what computers and what data can be inspected, as well as where and when. There is not likely to be any seizing of computers, and quite a long time may take place between the time the request to inspect a computer is made and the time the computer is made available to be inspected. It is common for one party to have access to a very limited area of data from the other party’s computer. During this time, a defendant may take the opportunity to attempt to hide or destroy data. The author has had several cases wherein the computer needed for analysis was destroyed before the plaintiff had the opportunity to inspect. Such attempts at hiding data are often discovered by the digital forensic sleuth, who may in turn present evidence of such further wrongdoing in expert witness testimony.

Opportunities for learning techniques and interacting with other professionals may differ as well. While some computer forensic software suites and training, such as Access FTK, EnCase, or SMART Forensics are available to most who can pay, others, such as iLook are available only to law enforcement and military personnel. While many support and professional organizations and groups are available to all, some, such as the High Technology Crime Investigation Association (HTCIA) are not open to professionals who provide for criminal defense (with a few minor exceptions).
