he topology has 3 major networks: HQ, WORLD and BRANCH as shown in the diagram below. You are NOT allowed to do any modifications in the WORLD. As a result of a recent security breach in the company, there are several problems found in the following areas: A. Routing Protocols (26 marks) HQ internal network uses RIP for internal and external connections. Branch internal network uses RIP for internal and external connections. Every router in HQ should be able to ping every other router Routers should be configured with a default route You need to identify all the problems with the settings in each router, the impact on the network due to the problems and how you can rectify them. You need to implement your proposed solutions in the given packet tracer file. IP addresses of the router interfaces are NOT to be changed. Routers Problems Impact Solutions HQ Tech Router HQ LVL1 Router HQ LVL2 Router HQ Router Branch Router HQ WORLD BRANCH 4 B. Complaints from Staff (20 marks) You need to identify all the causes associated with the complaints shown in the table below and how you can rectify them. You do NOT need to mention any issues related to the settings in the router for this section. You need to implement your proposed solutions in the given packet tracer file. From Complaints Causes Solutions HQ Lvl2_user1 Not able to ping lvl1_user1 Not able to email lvl2_user2 Not able to ping lvl1 printer HQ Lvl1_user1 Not able to ping lvl1_user2 Branch Wireless_PC Not able to ping Branch Printer All HQ users Not able to type www.hq.com in the web browser to access the HQ server Not able to type www.world.com in the web browser to access the WWW server Not able to type www.branch.com in the web browser to access the BRANCH server C. Implementing Security Measures (24 marks) The company decides to improve the security of the company by implementing the following: 1. HQ_Router a. Set up NAT/PAT – allowing internal users to go to the external network but blocks all incoming connections with the exception of the HQ server which is accessible from the external network with the IP address 200.20.2.3 2. Branch Network a. DHCP to be set up to allocate IP addresses to the Branch users b. Block connection to WWW Server c. Add in Branch user3 to the Branch Switch using VLAN2 d. Branch user3 must be able to access the printer which is in VLAN1 e. Branch switch to disable all unused ports 3. All routers a. Configure a password for privileged EXEC mode (password – cisco) b. Configure a password for the console connection (password – class) c. Configure a password for the VTY connection (password – cisco) d. Configure encryption to all passwords e. Configure a message of the day banner f. Inactive session timeout on the console port and the virtual terminal after 30 seconds 5 You need to implement the above requirements in the given packet tracer file. Comment on the security measures being implemented and how you can further improve them D. Implementing VLAN (10 marks) Describe how you would implement VLAN to the HQ and BRANCH LAN. You need to implement this in the given packet tracer file.
