A general view of access control from a software perspective is that it is "someone else's problem" such as the operating system or the firewall. What is the reason for this attitude? Why is it good or bad? Justify your conclusion. Cryptography is one of the many security tools but is given more emphasis than most in the media and in most security courses. Explain the limitations of cryptography in your own words. What does cryptography provide? What are the main problems associated with using cryptography? Give at least two security problems that cannot be solved with cryptography. Justify your answers with examples and analysis. Give an example of sensitive data that should be protected by cryptography. Why would this be necessary? Who might stand to gain by exploiting this information if it were not protected?
