The acquisition of evidence in the digital world

The digital forensics is the process of recreation of what happened in a digital device. In the past this activity was limited only to computers (computer forensics then), now with the diffusion of new electronic devices that can store data on digital storage media or external, includes all the digital devices including mobile furniture,
digital cameras and even GPS devices (which is why we talk more generally of digital forensic ). As for the forensic pathology (forensic science that allows us to clarify how and when a person is deceased) digital forensics has been used to catch numerous crimes.
therefore can be summarized in very general terms, that the analysis of digital information, you can (unfortunately not always) to:

• reconstruct what was done with a computer
  
• recover deleted files (text documents , images, videos, etc...)
• find certain types of files.
• search for some phrases.
• examine areas of your computer.

Just as there has been the evolution of computer forensic to digital forensics, we can say that a new field of action is that of the Internet. Consequently, the application of the above mentioned techniques and methods of acquiring digital evidence from the Web, it is identified as forensic network.
