Introduction

The rapid change occurring in the present era of Information Technology and the computer has gained popularity in every aspect of our lives. This includes the use of computers by persons involved in the commission of crimes. Today, computers play a major role in almost every crime that is committed. Every crime that is committed is not necessarily a computer crime, but it does mean that law enforcement must become much more computer literate just to be able to keep up with the criminal element. Extending the rule of law into cyberspace is a critical step to create a trustworthy environment for people and different activities. Computer forensic science helps in maintaining the trustworthy environment for cyber society by applying a set of procedure and integrated analytical techniques to extract evidence when computer is used as evidence in criminal investigation. To provide this self-protection, computer forensic science should focus on implementing cyber security plans addressing people, process, and technology issues. There is need to commit the resources to educate employees on security practices, develop thorough plans for the handling of sensitive data, records and transactions, and incorporate robust security technology, such as firewalls, anti-virus software, intrusion detection tools, and authentication services, throughout the organizations' computer systems [1]. One of the major challenges, we are facing in law improvement in this new era is keeping up with growing demands of technology. Computer technology changes are so rapid that if a department is up to date today; their equipment will probably be outdated. Since the budgets have not been increased to keep pace with the rapid change in technology its becoming difficult for law enforcement agencies to keep up with this rapid change. The criminal element is not as challenged to keep pace, and being usually well financed and having the resources to continue purchasing the newer technologies.

Computer Forensic Science and Their Needs

Computer forensic is a science of acquiring, preserving, retrieving and presenting data that has been processed electronically and stored on computer media and according to Department Of Justice Federal Bureau of Investigation (FBI),computer forensic includes formalized and approved methodology to collect, analyze and present data in a court of law [2].

Computer forensic is needed due to the complex nature of electronic media. Traditional forensic science technique will not work in recovering and compiling computer based evidence. There is tremendous amount of fraud being committed using computers. Everyday thousands of computer users are bombarded with tons of bogus email. There is always someone on the internet typing to find a new victim to commit a crime against. There are fake websites, phony on line auctions, credit card fraud and a host of other crimes. The percentage of fraud is going up and people are losing thousands of dollars to cyber thieves. Attacks against companies are also very rampant on the internet. Hackers and other such individuals are always trying to compromise one system on the ...
