To  some Network Administrators, a firewall is the key component of their  infrastructure’s security. To others, a firewall is a hassle and a  barrier to accomplishing essential tasks. In most cases, the negative  view of firewalls stems from a basic misunderstanding of the nature of  firewalls and how they work. Your Chapter 2 readings this week will help  dispel this confusion.  

 This chapter clearly defines the fundamentals of firewalls. These  include what a firewall is, what a firewall does, how it performs these  tasks, why firewalls are necessary, the various firewall types, and  filtering mechanisms. Once you understand these fundamentals of  firewalls, you will be able to look beyond the unschooled opinions,  common mythology, and marketing hype surrounding them, and the crucial  benefits of effective firewall architecture will become clear. Like any  tool, firewalls are useful in solving a variety of problems and in  supporting essential network security.

 During  our week 2 collaborations we will discuss the impact and importance  relative to using firewalls ~ Are firewalls deterrents or obstacles to  employee productivity?
