A new field, cyber forensics, is in the process of extracting information and data from computer storage media accurately and reliably. However, this is not enough, because here the challenge lies in not just finding and collecting data, but preserving and presenting it in a manner that a judicial prospect will accept it. These are ways of combating cyber crime, which make it important for advances in the law enforcement, legal and forensic computing technical arenas. Today, it has become imperative for corporate managers, government agencies and law enforcement agencies to be conversant with the concept, approach and techniques surrounding cyber forensics. Here, electronic data is delicate and can be easily modified. In the event that it is attacked, information security professionals gather electronic evidence, trace and bring the criminals to the court of law. Considering the anonymity that the Internet throws up and the fact that criminals are among users of IT for social and financial discourses, it is necessary now that those responsible for taking critical information infrastructure resources should be empowered with the best tools for the job. One way of doing this is to use the power of cyber forensics. This book introduces cyber forensics from the perspectives of a systems administrator, an investigator and a common computer user. It dwells on the legal as well as the technical aspects associated with this discipline and explores the various models and approaches being used by forensic investigators.
