Cyber crime is on the increase. According to the FBI briefing, the number of cases continues to increase digital forensics. At first, the computer forensics industry literature uses the term to refer to a particular branch of forensic science dealing with the investigation and recovery of various materials found in computers. This field expanded to cover digital forensics analysis and investigation of all devices capable of storing digital data. This investigation is often done in conjunction with the crime, which is why it is important that the computer forensic investigator to have the necessary training, but also an interesting experience in the field.

The start getting volatile evidence, that the data can be changed or disappear quickly if no proper treatment. After this step, which can be difficult to do, depending on the level of investigator access a computer or digital device. Next is the physical storage purchases, including memory cards, hard drives, removable disk or USB drive, which will be captured forensics, to ensure continuity of operation of the system, while also using the device as a digital forensics world evidence.
The interesting, but also challenging and demanding.
