points and the addition of VLAN subnetting for improving network performance and reducing network congestion. Creating layers of firewalls and subnetting prevents other compromised devices from being used as an attack platform against the entire network. An additional firewall security layer is added to the two firewalls from the as-is diagram. This is a storage firewall to protect the back-up server. The back- up storage layer is an added layer of security that’s more controlled and will be less
