In which firewall architecture are multiple subnets deployed between the private network and the Internet which are separated by firewalls with increasingly stringent rules?
The correct response is three tiers. There are three-tier levels of firewall architecture. Single tier places the private network behind the firewall, two-tier use one firewall with three or more interfaces in a series, and three-tier use multiple subnets between private network and the internet separated by firewalls.
Why do we use three tiered firewall architecture?
Each tier represents a separate function and component of the overall application that can be separated and isolated from the overall application and the other components. Furthermore, the three-tier application typically stores sensitive information in the logic tier which ensures that this information remains isolated from the presentation tier.
