Digital forensics is the modern day version of forensic science and deals with the recovery and investigation of material found in digital devices. It is most often used in cybercrime situations, including but not limited to: attribution. identifying leaks within an organization.
For those working in the field, there are five critical steps in computer forensics , all of which contribute to a thorough and revealing investigation. Policy and Procedure Development. Evidence Assessment. Evidence Acquisition. Evidence Examination. Documenting and Reporting.

Digital evidence can be any sort of digital file from an electronic source. This includes email, text messages, instant messages, files and documents extracted from hard drives, electronic financial transactions, audio files, video files.
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.
Internal investigations – the three C’s – confidence. credibility. cost.
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.
There are four phases involved in the initial handling of digital evidence: identification , collection, acquisition, and preservation ( ISO/IEC 27037 ; see Cybercrime Module 4 on Introduction to Digital Forensics).
Evidence : Definition and Types Real evidence ; Demonstrative evidence ; Documentary evidence ; and. Testimonial evidence .
Forensic analysis is a method of investigating an incident by finding evidence that proves who, what, when, where and why of the incident. Five common types of forensic analysis , are deoxyribonucleic acid, or DNA, computer, handwriting, bloodstain and statement analysis .

Traditional forensic analysis methods include the following: Chromatography, spectroscopy, hair and fiber analysis, and serology (such as DNA examination ) Pathology, anthropology, odontology, toxicology, structural engineering, and examination of questionable documents.
4.3 Different types of digital forensics . Digital forensics is a constantly evolving scientific field with many sub-disciplines.
There are many sources of digital evidence, but for the purposes of this publication, the topic is divided into three major forensic categories of devices where evidence can be found: Internet-based, stand-alone computers or devices, and mobile devices .
The accreditation is evidence that regulatory frameworks have been met and that information can be trusted by a judge, jury, or employer for example. Angus Marshall said: ” Digital forensic methods should be tested before they’re used and customers should be offered known good methods before anything else is considered.
