4g Technology: Computer Forensics
Overview This paper will discuss the need for computer forensics to be practiced in an effective and legal way, outline basic technical issues, and point to references for further reading. It promotes the idea that the competent practice of computer forensics and awareness of applicable laws is essential for today’s networked organizations. This subject is important for managers who need to understand how computer forensics fits as a strategic element in overall organizational computer security. Network administrators and other computer security staff need to understand issues associated with computer forensics. Those who work in corporate governance, legal departments, or IT should find an overview of computer forensics in an organizational context useful.
What is Computer Forensics? If you manage or administer information systems and networks, you should understand computer forensics. Forensics is the process of using scientific knowledge for collecting, analyzing, and presenting evidence to the courts. (The word forensics means “to bring to the court.” ) Forensics deals primarily with the recovery and analysis of latent evidence. Latent evidence can take many forms, from fingerprints left on a window to DNA evidence recovered from blood stains to the files on a hard drive. Because computer forensics is a new discipline, there is little standardization and consistency across the courts and industry. As a result, it is not yet recognized as a formal “scientific” discipline. We define computer forensics as the discipline that combines elements of law and computer science to collect and analyze data from computer systems, networks, wireless communications, and storage devices in a way that is admissible as evidence in a court of law. Why is Computer Forensics Important? Adding the ability to practice sound computer forensics will help you ensure the overall integrity and survivability of your network infrastructure. You can help
