PREFACE
Computer forensics has become an essential tool
in the identification of misuse and abuse of
systems. Whilst widely utilised within law
enforcement, the rate of adoption by organisations
has been somewhat slower, with many
organisations focusing upon the traditional
security countermeasures to prevent an attack from
occurring in the first place. Such an approach is
certainly essential, but it is also well understood
that no system or network is completely secure.
Therefore, organisations will inevitably experience
a
cyberattack.
Moreover,
traditional
countermeasures do little to combat the significant
threat that exists from within the organisation.
Computer forensics is an invaluable tool for an
organisation in understanding the nature of an
incident and being able to recreate the crime.
The purpose of this pocket book is to provide an
introduction to the tools, techniques and
procedures utilised within computer forensics, and
in particular focus upon aspects that relate to
organisations. Specifically, the book will look to:
develop the general knowledge and skills
required to understand the nature of computer
forensics;
provide an appreciation of the technical
complexities that exist; and
allow the reader to understand the changing
nature of the field and the subsequent effects
that it will have upon an organisation.
