Cybercrime is the crime which involves the use of computers or other digital devices. Cyber-crimes are also known as digital crimes. In a cyber-crime, the computers or other digital devices may be a tool used in the crime, the target of the crime or a storage medium for storing the evidence of the committed crime.
The use of computers and internet has become obligatory in all aspects of modern life. Most of the information processing done in these days is extensively dependent on the use of information technologies. Therefore, it has become extremely important to prevent, control as well as investigate cyber activities in order to protect the informational, financial and other assets of an individual or an organization. The digital assets of individuals and institutions should be protected sufficiently in order to maintain the CIA system of digital information which includes the factors of confidentiality, integrity, and availability of digital assets. The information present in the human brains, in transit or stored in physical or digital media needs to be protected to maintain their authenticity and confidentiality. These facts establish the high requirement and relevance of understanding cyber-crime in order to control and prevent these crimes. The research work will be segregated into three categories for the ease of answering the research questions adequately. These categories are the prevention of cyber-crimes, the control of cyber-crimes and the investigation of cybercrimes.  .Research questions
