The tracks can be difficult to follow, but they are still there. Similarly, any person who commits a digital crime, leaves traces on the compromised system.

They are highly volatile and may be modified during the analysis if the proper precautions are not taken.Įvery person who goes through a crime scene leaves something of himself and takes something with him.

You can verify that change with the right methods.Evidence of this nature can be duplicated exactly.Digital evidence is information in digital format, capable of determining if a computer system has suffered a violation, or that provide a connection to the victim or with the attacker.The researcher must be able to identify the evidence from the information he has previously collected. In such cases, the process of forensic analysis can become extremely complex and time consuming, requiring the development of new technologies for searching for evidence.Īny digital information able to determine that there was an intrusion or that indicates any link between the attacker and the victim, between the invasion and the attacker, could be considered as evidence. These traces can be extremely difficult or virtually impossible to be identified and followed, but they exist. In the virtual world of computers, the Principle of Exchange of Locard is still mostly valid: wherever the attacker has been, he leaves traces. According to this principle, anyone or anything that enters a crime scene, carries something of the place and leaves something behind after parting. One of the fundamental principles of forensics is the Locard Exchange Principle. At the end of the reading, you will understand how to iOS forensic analysis works.Learn the key concepts in a simple manner.Compare software to know which is best for each case.Standardized technique to avoid errors.Dear readers, you will increase your knowledge in the area of preparation and effective methods for applying forensic peripheral.Information about the device on which you will apply the method.Readers, for you to understand these items, you just need to have a little knowledge about the rationale behind the technique and analysis of forensic.The use of scientific methods for preserving, collecting, restoration, identification, documentation and presentation of digital evidence is what we call computer forensics. It is known that with the increased use of mobile devices, cyber-crimes in these types of applications have multiplied, forensic science has evolved so that the techniques and tools have become more specific to certain types of platform.
