Question: 1. Take a tour of your building on campus or at work. What is secured at night when workers are absent? Record the location and type of physical access control devices. How do these access controls change at night when workers are absent? How well trained do guards and other employees appear to be? Do they allow "piggy backing"(somebody slipping into a facility behind an authorized individual without being challenged)? What are the policies for visitors and contractors? How does this all impact physical security?

2. If possible at either your place of employment or your school, attempt to determine how easy it would be to perform dumpster diving to gain access to information at the site. Are trash receptacles easy to gain access to? Are documents shredded before being discarded? Are areas where trash is stored easily accessible?

3. Perform a search on web for articles and stories about social engineering attacks or reverse social engineering attacks. Choose and read five or six articles. How many of the attacks were successful? How many failed and why? How could those that may have initially succeeded been prevented.

4. Describe the three basic types of network topologies and provide a sample diagram of each type.

5. How are authentication and authorization alike and how are they different? What is the relationship, if any, between the two?
