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.
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.

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 .
Incident response is typically broken down into six phases ; preparation, identification, containment, eradication, recovery and lessons learned.
Common search patterns include the spiral, strip/line, grid, zone/quadrant, and pie/ wheel.
INTERVIEW , EXAMINE, PHOTOGRAPH , SKETCH and PROCESS.
Terms in this set (5) Interview witnesses/people involved to establish the theory of the case. Examine the scene using a systematic search method. Sketch the scene to create an overall diagram. Photograph the scene, the evidence, the body to get detailed pictures of what everything looked like at that moment.
Fingerprint Evidence . Latent prints are left by the contact of the palmar surfaces of the hands and/or bare feet of a person are probably the most valuable piece of evidence at any crime scene .
Rooted in the Latin word vestigare , meaning “trace out,” investigators gather facts in order to trace out the whole picture.
Define known and unknown evidence . Known evidence – objects whose source is known at time it was collected (standard/reference sample) Unknown evidence – collected at crime scene that has an unknown orgin. Define individual & class characteristics. Individual characteristics- evidence that only arises from one source.
