With the rapid growth of computer and network systems in recent years, there has also been a corresponding increase in cyber-crime. Cyber-crime takes many forms and has garnered much attention in the media, making information security a more urgent and important priority. In order to fight cyber-crime, criminal evidence must be gathered from these computer-based systems. This is quite different from the collection of conventional criminal evidence and can confuse investigators attempting to deal with the forensics of cyber-crime, highlighting the importance of computer forensics. In this paper, we offer solutions to guard against cyber-crime through the implementation of software toolkits for computer-based systems. In this way, those who engage in criminal acts in cyber-space can be more easily apprehended.

The rapid development in computer and Internet technology has brought forth a tremendous increase in computer and Internet crime. The most commonly seen crimes involve hacking into computer systems and computer viruses. Now these terrorists also threaten and cause damage via the Internet. Conventional crimes, such as fraud and money laundering, have been creatively changed into new forms by the rising popularity of the Internet. If we choose to ignore cyber-crime, the attackers' ambition and greed will be encouraged and we will face more serious criminal behaviors. What we must do is fight these cyber-crimes by tracking the instigators through the proper procedures. This is the best way to protect our networks and keep cyberspace secure.
However, network interaction is based on principles of reliability and trust between both users and administrators: users “believe” Internet networks will not reveal their secrets, while network administrators also “believe” users will obey the rules when using the services provided by the website. Criminal behavior can damage this agreement of trust between both parties. Not only can lack of trust damage the development of Internet trade, but it can also affect the network services provided by network technology. When users are unable to trust a communication network, websites involved in network communication, connection and trading are simply nominal. Hence, when seeking secure data and website maintenance, we must discuss how legal methods and procedures can be applied to investigate those who engage in cyber and network crime.
In the past, when prosecutors and police investigated a crime, the investigators who analyzed the evidence also presented that evidence to assist the judge in making the correct decision. Criminal investigation training courses always include some forensics in order to understand what prosecutors and judges require in regard to evidence. The focus is on the collection and preservation of effective evidence. In other words, at a computer-based crime scene, the highest attention must be given to specifying digital evidence. The major feature which distinguishes cyber-crime from conventional crime is that the evidence at the crime scene is represented in electronic form. This also makes it easier for the criminal to store, conceal, propagate and remove the information and why it is more difficult ...
