Forensic Toolkit – What’s in It?

In the world of digital forensics, the well prepared investigator needs a forensic toolkit. The tools that this person will use will help her or him gather evidence of white collar crime or fraud, document the evidence of the occurrence, and, perhaps, place that investigator on the witness stand for expert testimony in what ever legal proceedings come out of the process. The tools used by these investigators are primarily software tools, though there are a few hardware considerations as well.

The basic computer forensic toolkit will probably be contained on a CD or DVD and be presented primarily in a word processing format. Any computer forensic investigation produces a mammoth amount of paperwork, since the goal of the investigation is to document absolutely everything that is found. These toolkit CD’s are designed to supply the investigator with tried and true forms and templates that will allow to investigator to document everything that is found. They also serve as an effective check list to aid the investigation team in ensuring that no step is missed and that everything is done in the correct order.

Another major component of the toolkit will be templates and tools to assist in the presentation of the findings of the investigation to management. It is vital that all findings be reported in a manner that is professional, unbiased, complete, and scientifically sound. This is the end product of the investigation, and what management sees as being what they paid the investigators to actually do. This reporting may also end up being the basis (and exhibits) of the legal proceedings that may arise from the process, so it is vital that these reports and presentations be accurate, clear, and completely aligned with the law.

The main non software tool that is used in a computer forensic toolkit is an imaging device. Making an exact image of the hard drive (or other storage medium) of the computer is the most common first step in the capture of data. It is absolutely required that a “clean” copy of the computer’s memory and stored data be in place, so that the investigators are sure that they are looking at and analyzing the data in the same precise pattern in which it occurs on the computer in question. There are many brands of device available, and they all have the same basic function.

First, these devices must make an exact copy of the data. Secondly, the usually perform the copy at the sector level of the disk as a bit stream process (as opposed to a simple file copy process). This method makes a more complete and accurate copy of the data, which, in turn, allows for a more thorough and accurate analysis.

Be An Expert In Computer Forensic

Computer forensics is an emerging field. There are great job opening in this fields in government as well as private institutions. Now, the technology is growing at a greater pace, so the demand for experts to tackle the crimes in this field is also increasing. The evidences found out by a computer forensic expert are legally accepted in most of the countries.

The police department will also be taking the assistance of forensics experts. They can have a great contribution to crimes related to terrorism. Most of the organizers of the crime will be using the internet technology, therefore an expert in this field can only hack their identity. Many corporate offices are also choosing forensic experts to solve the crimes in their organization. The scientific methodology behind the crimes is solved by experts.

There are many cases where the crimes have been solved by the experts and the victim is punished legally with the forensic evidences. The secret information in the police department, government offices, corporate office and other fields are kept safe to avoid hackers. The hacking of confidential details is legally punishable.These type of crimes can be proved and established by an expert forensic investigator.

The digital information can be accessed by a forensic investigator. Malpractices in the government law affairs with the use of technology can be prevented by an established investigator of forensic. The information on computer hard drive and other digital media will be the evidence collected by them. Financial theft in Multinational companies is caught by the help of forensic investigators. They can have an employment in the corporate fields also to safeguard the company projects details and other information.

This potential field is giving many job opportunities to the future generation. There are many colleges and universities offering the course for forensic technology.

Computer Forensic Processes to Get Accurate Results

Today we shall talk about computer forensics and including the overall concept of computer forensics. What is a digital trail? What is process and restrictions exist as well as defining the needs of a computer forensic investigator.

Basic idea of computer forensic is to investigate computer equipment and any associated component determine if it has been used or what is level of crime or any type of unauthorized computer activity accrue.

Now the reason we define the difference between crime and unauthorized activity a crime constitute violate a federal or other law which is established by any organization. This going to take place across the border, if it is a public computer or any part of an organization.

Unauthorized activities are usually the activities which are restricted by policy in corporate or work place environment. Forensic investigator play role for these type of investigation even it is a criminal activity or any activity which sabotage the corporate policy.

Computer forensics based on 5 basic investigation procedures which are

1. Preservation

2. Acquisition

3. Analysis

4. Discovery

5. Documentation and presentation of evidence.

Evidence must be collected with accordance, proper method and accepted forensic techniques otherwise they will be not accepted or useful for any crime investigation.

First of all we shall talk about preservation, this process is very critical and you have to be very careful about this because a little mistake or carelessness can destroy or eliminate your evidence. This evidence is normally based on digital trails and digital finger prints.

Second phase is acquisition process. This process is after preservation and this is the process about how to gain your evidences from digital crime scene. It is based on high-end techniques and tool based. And only performed by a certified forensic expert.

Next phase is analysis and discovery. Here we analysis all evidences and isolate non relative or relative evidences and break down them into proper evidences which is relevant to the crime. Now we have to documentation and make able to present them as proper evidence. This phase is especially for litigation purposes and this will be served to proof the crime.

Here we have some legally binding situations for evidences. Evidences must be handles a proper legal way and acceptable standards and for this purpose the computer forensic personnel must be specially trained in analysis techniques and also have a great knowledge of computer hardware and software.

Because when evidences are for litigation, federal law agencies have their own standards of evidences so the evidences must be collect in these manners. Collecting and handling must be through proper chain of custody and you must know the standards of the agency where you have to present evidences. As a computer forensics investigator the personnel must be expert in documentation, analysis, acquisition and preservation. Without a proper documentation and presentation you can get your goals.
