Question requires you to develop firewall rules based on a fictitious organisation.
Scenario:
You work for a security-conscious company, xC-Cure, who develop encryption technologies for large corporate and defence customers world-wide. Your role is a junior security specialist and you have recently been asked to plan for the deployment of a new firewall.
The firewall is structured around an external filtering router (using NAT)with three(3) interfaces. The external (public) interface is Internet facing and has a public IP of 120.9.20.1. The second interface has an IP of 10.1.0.1 and is the gateway to the DMZ network (10.1.0.0). The third interface has an IP of 10.2.0.1 and is the gateway to the intranet (10.2.0.0). The firewall also acts as a VPN tunnel server on its public Internet interface.
While certain traffic can flow between the DMZ and the intranet, Internet initiated connections should not enter the intranet. Two sets of filtering rules are applied: one for traffic flowing in and out of the Internet interface, another for traffic flowing between the DMZ and the intranet.
