Computer technology is the major integral part of everyday human life, and it is growing rapidly, as are computer crimes such as financial fraud, unauthorized intrusion, identity theft and intellectual theft. To counteract those computer-related crimes, Computer Forensics plays a very important role. “Computer Forensics involves obtaining and analysing digital information for use as evidence in civil, criminal or administrative cases (Nelson, B., et al., 2008)”. A Computer Forensic Investigation generally investigates the data which could be taken from computer hard disks or any other storage devices with adherence to standard policies and procedures to determine if those devices have been compromised by unauthorised access or not. Computer Forensics Investigators work as a team to investigate the incident and conduct the forensic analysis by using various methodologies (e.g. Static and Dynamic) and tools (e.g. ProDiscover or Encase) to ensure the computer network system is secure in an organization.
