You are a network security officer who has finally convinced their company to buy a firewall to secure their network from Internet based threats. Your task is to create the rule list for this new firewall. You may make the following assumptions about this network: • This will be a Triple-homed firewall with one interface connected to the Internal LAN zone, another connected to the Internet zone, and the final interface connected to a DMZ. • The firewall's three IPs will be: Internal - 172.16.255.1, External - 66.43.24.1, DMZ - 66.43.24.17 • The company operates a DMZ for their online services in the 66.43.24.16/28 subnet. • There is an internal server farm occupying the 172.16.100.0/24 subnet. • The web development team occupies the 172.16.50.0/24 subnet. • The accounting department occupies the 172.16.20.0/24 and 172.16.21.0/24 subnets. • Remote access users use the 172.16.10.0/24 subnet. • Two business partners, ACME and FredCo, connect to the company through dedicated circuits; they use the 192.168.100.0/24 and 192.168.200.0/24 subnets respectively. • The firewall is stateful and should exercise a deny-by-default policy.
