Computer forensics labs are high-tech labs that are used for rendering computer forensic and other investigative services. Various software and techniques are used during the process of investigation, including password cracker, email converters, or the EnCase or Forensic Toolkit (FTK) software applications.
Initially, an exact replica of the hard disk drive is created, so that the evidence can be evaluated and processed from a forensic file. The identifying leads and computer evidence contained in files proves critical in determining the outcome of the case. The finds are then documented, and the opinions of experts are taken. The expert witness testimony proves very helpful to clarify technical computer issues in the litigation process. With the help of customized software, the forensics investigators can retrieve deleted data, hidden data and password-protected data. The retrieved data is then carefully documented and recorded in reports that are then presented at times of litigation.
On an average only 10 percent of these files may actually be used in litigation cases. Customized software is used to filter out unnecessary data, based on data relevant parameters covered on the software. Around 25 percent of the original data set can be filtered, using intelligent filtering methods. It is also used to remove duplicated items from the database, saving thousands of dollars for the company.
Computer evidence often decides the results of civil or criminal actions. Cases involving trading secrets, commercial disputes, misdemeanor and felony crimes can be or lost with the introduction of lost computer evidence. The latest high tech labs are equipped to recover such data.
Computers are widely used for criminal activities such as hacking, credit card frauds and intellectual property right crimes. This has created a rising need for forensic labs that are capable of collecting lost electronic evidences. These high-tech computer forensic labs are certainly an alarm for lawbreakers.
