10. Reason for cyber crime
1. 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.
