discussion

To help ease you into the course this semester, this chapter provides a refresher to some security concepts. Threats to network security, common types of malicious software, and potential defense mechanisms are covered.

Answer the following questions, and then comment as required on two classmate posts:

1. The book explains the three goals of network security are confidentiality, integrity, and availability. How does increased availability affect integrity and confidentiality? Do you think the goals are mutually exclusive?
   
   
2. Research some typical software firewall and antivirus options. With each option, seek out reviews to help determine each software package’s viability.  Make your recommendation to the class.  You can look at this from a home or business aspect.
   
   
3. Research what online services are most commonly attacked and exploited. Compile a list of the most exploited services on the Internet, and explain why it is so.
