In litigation, an attorney must determine whether a Request for Production of Documents will obtain all relevant evidence. You might simply ask yourself whether you want to discover a part of the relevant information i. It is not unrealistic to believe that information that is helpful to a matter would be saved on a computer. At the same time, that which is harmful would be deleted, hidden, or rendered invisible. For example, in sexual harassment cases, it is not unusual to discover deleted emails and other data invisible to the operating system that significantly affects the case.
Computer forensic analysis extracts all the emails, memos, and data that can be viewed with the operating system, as well as all invisible data. In many cases, the hidden data completely changes the nature of a claim or defence and ultimately effects settlement strategy. In any situation in which one or more computers may have been misused, it is essential to call a forensic expert. Computer forensics is a complex and often misunderstood practice.
The examiner is presented with massive volumes of data, and forced to work within the constraints of computer processing capabilities. Proper computer investigation is a multi-step, time and labour-intensive process.
This article is designed as a primer on the computer forensics process and generally what examiners will go through to conduct an investigation. It is meant to provide a basic understanding of how a computer stores, accesses and processes data so that you, the client, has a more definite sense of the work and time necessary for a full and thorough forensics investigation.
It is by no means complete, as every study is different, and this is not designed to delve into every eventuality. It is to be viewed and used as a guideline only. This is an often asked question, because in some cases, the window for acquisition is minimal, as in a situation where an employee will only be gone for a few hours, or the activity will disrupt some other work product. It depends on several factors that the examiner cannot control. It is dictated by things like the type of formatting on the subject drive, the rotational speed of the journey, data density and volume, drive interface and construction, and tools used.
In the case of using a hardware device as mentioned above, a general rule of thumb would be GB of data per minute to create the forensic image. Check out our range of Top private investigators to help in your problem with legal nature, or business-related, or private and personal related. Translated, this means that a GB hard drive will take roughly minutes to image. A 1 TERAbyte hard drive will take approximately 3.
These are just imaging times. Immediately following the imaging process, a verification process has to be performed to ensure the integrity of the evidence collected. This roughly takes as long as the initial imaging phase and needs to be performed during the acquisition process. In the case of an older hard drive or a problematic hard drive with structural problems, the imaging process may only happen at a rate of 1 GB per minute.
Hard drives in external enclosures that connect via USB must be dismantled which can be destructive in some cases , or else their acquisition timeline will be increased. Many times an examiner has shown up at a location only to find that the computer has more than one hard drive in it, or is a server with multiple drives in it.
Obviously, this severely impacts the acquisition timeline, not to mention the cost. This again is dependent on the amount of RAM in the network, but can take anywhere from a few minutes to more than an hour, and cannot be done concurrently with the hard drive acquisition process.
As you can see, from start to finish, the acquisition phase can take the better part of an entire day just by itself before any analysis is started! Materials are seized as soon as illegal content is identified to prevent the destruction of evidence. If there is sufficient evidence of receipt or distribution of confirmation, a search warrant can be obtained. Once child porn is viewed, the computer is generally seized in place, and a warrant obtained if necessary.
A forensic computer specialist then processes it, and all suspected material is reviewed and identified to the extent possible. Looking for help in digital forensics? Look no further, Private Investigators has you covered. We receive lots of questions related to our data forensics services, so we have compiled a list of the most common questions below.
Contact us today for a free consultation. Computer Forensics is the analysis of information contained within computer systems. We will work with you to identify where your data is located. We will document the legal chain of custody of the media and we will make a bit by bit copy and preserve the original. The computer forensic analysis will examine and extract the data that can be viewed by the operating system, as well as data that is invisible to the operating system including deleted data that has not been overwritten.
The Computer Forensics Investigator also addresses the legal issues associated with electronic evidence, such as relevant case law, how to navigate the discovery process, protection of privilege, and in general, working with attorneys and other professionals.
This includes existing active files, and invisible files, hidden files, password-protected files, and encrypted files. Special skills, tools and software are needed to obtain this type of information or evidence. A Computer Forensics expert can recover all deleted files and other data that have not yet been overwritten. As a computer is used, the operating system is constantly writing data to the hard drive.
From time to time, the operating system will save new data on a hard drive by overwriting data that exists on the drive but is no longer needed by the operating system. A deleted file, for example, will remain present on a hard drive until the operating system overwrites all or some of the file.
The ongoing use of a computer system may destroy data that could have been extracted before being overwritten. That is why we stress that time may be of the essence. Fortunately, the costs of acquisition are very reasonable, and the process is generally not disruptive. At the conclusion of an investigation, our Computer Forensics investigator will provide a detailed analysis of the computer system in a written report.
We will also provide our clients with a copy of all relevant data in digital form. In the past, computer forensic examinations could run tens of thousands of dollars because of the manpower necessary to thoroughly examine a hard-drive. With the advancement of technology in the computer forensics arena, that is no longer the case. I will make sure I start checking references and resumes and see who would be the best fit for us. Yes, we all should be careful about this and hiring a good detective agency.
