Q​uestion Set 1 – Q​uestion 1.12 Now, you become busier and would like to provide stronger security protection on your local office site. You want to upgrade your firewall system from a dual-home server to DMZ. The initial design is presented below in Figure 1.3.  Figure 1.3 System with DMZ Network diagram for a system with DMZ including two servers connected to an interior router, a webserver in the DMZ between two routers, and a public-facing server connected to the external router. A monitor is also present in the diagram.   In the new system, because the website is accessible from the public domain, ideally the webserver should be allocated on a separate private network guarded by an interior firewall. Thus, you designed a screened network firewall, where the internal network system is separated as a private network containing a host and a DB, the webserver is placed in the perimeter network (DMZ) set between the interior router and exterior router. The IP addresses in your system are set as as shown in the table below (Table 1.2): In this network setup, both DMZ and private networks will set up using private network addresses.  Node-to-IP Mapping in Network Setup Node IP Host 192.168.0.10 Interior Router 192.168.0.30 Exterior Router 172.16.0.10 Webserver 172.16.0.20 DB 192.168.0.20 Which of the following suggested setups can maximize the system’s security?

Question Set 2 – 1.17 Continuing the scenario presented in Question Set 1, you would now like to migrate your organization’s networking system to a cloud platform. Specifically, you want to use SDN and NFV techniques to build up your network infrastructure. In order to set up a programmable networking environment, you need to understand some foundations of virtual networking solutions. Which of the following statements are not true regarding classifying VPN protocols? (select all that apply)   Figure 1.1 Network Setup Diagram showing a network configuration with labeled components.

A monitor is also present in the diagram.

Question Set 1 – 1.13 If you also set up NAT on the interior router, the traffic initiated from the host to the web server (202.10.19.132) on the public domain needs to traverse two NAT (double NAT).  Assuming that the default firewall policy is DROP, and IPs are shown in the table in Q1.11. Which of the following iptables NAT configurations is correct? (Only consider one way traffic going from the host to internet.)

Q​uestion Set 1 – 1.14 Supposing you want to incorporate your branch office’s web service running on web2 as part of your web services that are protected by your DMZ security monitoring and checking modules, you may want to set up a VPN.  In this situation, which of the following statements are correct? (select all that apply)   Figure 1.3 System with DMZ Network diagram for a system with DMZ including two servers connected to an interior router, a webserver in the DMZ between two routers, and a public-facing server connected to the external router.

Q​uestion Set 1 – Q​uestion 1.3 Consider the network set-up presented in Figure 1.1. Suppose that on the public domain, a webserver is accessible with an IP address 202.10.19.132. To allow the client access to the web server, you will need to set up NAT on the gateway G.  Which of the following options correctly describes the NAT? Figure 1.1 Network Setup Diagram showing a network configuration with labeled components. From left to right: interface I1, gateway G, Internet cloud, interface I5, and server/router I6.
