Introduction of Computer Forensics

The procedure starts with identifying the devices used and collecting the preliminary evidence on the crime scene. Then the court warrant is obtained for the seizures of the evidences which leads to the seizure of the evidences. The evidences are then transported to the forensics lab for further investigations and the procedure of transportation of the evidence from the crime scene to labs are called chain of custody. The evidences are then copied for analysis and the original evidence is kept safe because analysis are always done on the copied evidence and not the original evidences.

The analysis is then done on the copied evidence for suspicious activities and accordingly the findings are documented in a non technical tone. The documented findings are then presented in the court of law for further investigations.
