Firewall Advantages and Limitations Now that the theory behind a firewall has been presented, this section will focus on examining the several kinds of firewalls available as well as highlighting the kind of protection they can offer. The position that a firewall sits with respect to the rest of...
Conceptually, there are two types of firewalls: 1. Network Level 2. Application Level They are not as different as you might think, and latest technologies are blurring the distinction to the point where it’s no longer clear if either one is “better” or “worse.” As always, you need to...
