Reason for cyber crime1. Easy to Access: - The problem encountered in guarding a computer system from unauthorized access is that there is every possibility of breach not due to human error but due to the complex technology.2. Complex: - The computers work on operating systems and these operating systems in turn are composed of millions of codes. Human mind is fallible and it is not possible that there might not be a lapse at any stage.3. Negligence: - Negligence is very closely connected with human conduct. It is therefore very probable that while protecting the computer system there might be any negligence, which in turn provides a cyber-criminal to gain access and control over the computer system. 4. Loss of Evidence: - Loss of evidence is a very common & obvious problem as all the data are routinely destroyed.
