Principal activity of cybercrime is the attack on content, computer systems and communication systems owned by others or the public in cyberspace. The phenomenon of cybercrime is to watch out for the evil is rather different from other crimes in general. Cybercrime can be done without knowing the territorial boundaries and does not require direct interaction between the offender to the victim of crime. Here are ways to overcome them:
a. Securing the system
Real purpose of a security system is to prevent the destruction of part of the system because it was invaded by unwanted users. Security integrated system is needed to minimize the possibility of destruction. Build a security system must be integrated steps in the overall subsistence, in order to narrow or even close the gaps unauthorized actions that harm. Securing personally do starting from the installation of the system until it finally headed to the stage of physical security and data security. The security system of the attack through the network can also be done by securing FTP, SMTP, Telnet and Web server security.
b. Global Poverty
The Organization for Economic Cooperation and Development (OECD) have created guidelines for policy makers dealing with computer-related crime, where in 1986 the OECD has published a report entitled Computer-Related Crime: Analysis of Legal Policy. According to the OECD, several important steps that must be done every state in the response to cybercrime are:
1. modernizing the national criminal law and its procedural law.
2. improving national computer network security system according to international standards.
3. enhance the understanding and skills of law enforcement officials regarding the prevention, investigation
and prosecution of matters related to cybercrime.
4. increase citizen awareness about the problem of cybercrime and the importance of preventing crime occurred.
5. enhance cooperation between countries, whether bilateral, regional or multilateral, in tackling cybercrime.

The need for increased computer network technology. In addition to the information media, the Internet community is also commercial activities become the largest and fastest-growing as well as through the various borders. Even through this network activity on world markets could be known for 24 hours. Via the internet or also called cyberspace, anything can be done. Positive aspects of the virtual world is of course adds to the trend of technology development world with all forms of human creativity. However, negative impacts could not be avoided.

Along with the development of Internet technologies, lead to the emergence of crime called "cybercrime" or crime through the Internet. The emergence of several cases of "cybercrime" in Indonesia, such as credit card theft, hacking several websites, intercepting data transmission to others, such as email, and manipulate data in a way that is not desired to prepare orders into a computer programmer. Thus, in computer crime and the possible existence of a formal offense offense materially. Formal offense is the act of a person who enters another person's computer without permission, while the material is an act offense causing serious harm to others. The existence of cybercrime has become a threat stability, so that the government compensate difficult crimes techniques with computer technology, especially the Internet and intranet.
