Question
Refer to the exhibit. An enterprise underwent a DoS attack sourced from the Internet on their web servers. Their existing firewall failed to handle the attack resulting in services being unavailable for several hours. The enterprise has decided to add a second firewall layer that will act as a back-end firewall. Both sets of firewalls will be set up to handle DoS attacks, so an identical situation is unlikely to happen again in the future. The current firewall hardware supports virtualization, meaning the same physical hardware can be used as both front-end and back-end firewall. What provides an optimal solution to ensure highest level of security?
Exhibit

- BAcquire a firewall from a different vendor and deploy as back-end firewalls.
