Fundamentals of Digital Forensics

Digital forensic methods and techniques face great challenges at present, forcing the forensic investigator into a continuous need for research and improvement. Traditionally, digital forensic investigators have systematically sought a much closer look at artefacts in search of a possible clue that may be evidence of a crime. But as technologies evolve, the procedures and approaches to finding this crime evidence need to be improved and adapted. There are lots of new small challenges for digital forensics to overcome, however we present a short summary in 3 categories:

Technicals:

•       Different types of storage;

•       Encryption;

•       Stegnography;

•       Antiforensic Techniques;

•       Acquisition and Analysis in Live Data Forensics;

•       Concealment and Disposal of data;

•       Data volatility;

•       Network shares;

•       …

Legals:

•       Privacy;

•       Data Protection;

•       Delay in adapting laws to the technological reality;

•       Acting at the scene of the crime;

•       Data analysis and handling;

•       …

Resources:

•       The increase in the volume of data;

•       Complexity of distributed data storage systems;

•       …
