The purpose of a computer and digital forensic examination is to examine and analyze computer and digital evidence for the purpose of identification, collection, and preservation of evidence .
The purpose of computer forensics techniques is to search, preserve and analyze information on computer systems to find potential evidence for a trial. Lawyers can contest the validity of the evidence when the case goes to court. Some people say that using digital information as evidence is a bad idea.
Computer forensics , also known as digital forensics , on the other hand is a much more specific discipline, which involves the analysis of computers and other electronic devices in order to produce legal evidence of a crime or unauthorised action.
While most sections within a forensic laboratory have some degree of wet chemistry, the toxicology, drug chemistry, and biology sections are typically the most chemical-intensive. Many other laboratory sections in the forensic lab , including the blood alcohol and latent prints sections, deal with biological evidence.

The computer forensics workstation should have facilities and tools to: Support hardware-based local and remote network drive duplication. Validate the image and the file’s integrity. Identify the date and time of creation, access and modification of a file. Identify deleted files. Support removable media.
Is computer forensics a good career ? Digital forensics , or to put it differently, computer forensics , is the application of scientific investigatory techniques to digital crimes and attacks. In other words, it is a crucial aspect of law and business in the internet age and can be a rewarding and lucrative career path.
A bachelor’s degree in computer forensics or a similar area is generally required to earn a position as a computer forensics investigator.
15 to 35 hours
The first rule of digital forensics is to preserve the original evidence. During the analysis phase, the digital forensics analyst or computer hacking forensics investigator (CHFI) recovers evidence material using a variety of different tools and strategies.
Requirements to Become a Forensic Expert Bachelor’s degree in Computer Science or Engineering. Bachelor of Science in Cyber Security (preferred) Master of Science in Cyber Security with Digital Forensic specialization (preferred)
Computer forensics is also important because it can save your organization money. From a technical standpoint, the main goal of computer forensics is to identify, collect, preserve, and analyze data in a way that preserves the integrity of the evidence collected so it can be used effectively in a legal case.
These four major federal crime labs help investigate and enforce criminal laws beyond the jurisdictional boundaries of state and local forces: FBI (Federal Bureau of Investigation), DEA (Drug Enforcement Agency), Bureau of Alcohol, Tobacco, Firearms and Explosives, and U.S. Postal Inspection Service .
Forensic science technicians typically need at least a bachelor’s degree in a natural science, such as chemistry or biology, or in forensic science . On-the-job training is generally required for both those who investigate crime scenes and those who work in labs.
Analysts or investigators will typically soak up pooled blood , or swab small samples of dried blood in order to determine if it is human blood and then develop a DNA profile. This becomes critical when there are multiple victims.
