Computer Forensic Tools
The National Institute of Standards and Technology's goal is to establish the methodology for testing computer forensic software tools by using focus groups to perform investigations using these same tools. After many successful tests, the forensic tools are introduced into law enforcement agencies and the Federal Bureau of Investigations.

Computer Forensic Tools Testing
-
At the National Institute of Standards and Technology, there is a new project underway called computer forensic tool testing, or CFTT. This project will help in the area of computer-related crimes. Law enforcement agencies use different automated tools to assist in the investigation of crimes involving computers.
Forensic Expert Witness Association

There has been high demand for new and improved computer forensic tools in the past century because the rate of crime has risen exponentially. The court system relies on accurate forensic testimony to secure the convictions of criminals who would otherwise be set free on circumstantial evidence. In the past decade, hundreds of innocent people have been set free from prisons because of new forensic tools.

Critical evidence created by these tools is routinely used in criminal cases, but there are no set standards by which to judge the accuracy of the results. This is why CFTT will give the necessary information to improve tools so better and informed choices can be made. The goal of CFTT is to ensure that these tools produce reliable and accurate test results.
One of the tests used in the CFTT is the Digital Forensic String Search Tool, better known as DFSS, which provides a border between a user and a search engine. The user is looking for a match from the search universe to a target search string. The requirements in this test are used to obtain general statements of conditions that are checked after a test is implemented.
Recovering Lost Data
-
At the Data Recovery Center, a suspect's computer can be analyzed for lost data that can be used as crucial evidence for a conviction in a case.
How forensics Have Evolved
-
The use of DNA evidence has been called "the hand of God," as it is now creating checks and balances in the court systems, setting innocent people free and imprisoning the guilty. The use of computer forensic tools has evolved from a pseudo science into a credible medium of truth.
Forensics Procedures and Analysis Tools
-
Field triage has shown quick and effective analysis of suspect evidence that can be critical to a case.
Computers have become the main source of evidence in many crimes
-
The increase in technology is changing our perceptions of what is defined as evidence in a criminal investigation. Evidence that used to be based on physical documents and expert testimony has now turned into evidence that is stored on hard drives, digital media and web accounts. As computer crimes are becoming more commonplace, the use of proper procedures and tools are needed to contend with these new challenges faced by law enforcement agencies worldwide.
