Assignment Description Tasks: There are two parts to this assignment, part A and part B. A. Design and model Implement (in Netsim) of VPN for Sigma Inc. by addressing the following criteria. See detailed instructions in the next section. (25 marks) B. Presentation (5 marks) Part A: Design and Report Two broad areas to be considered for VPN network design in this assignment are as under; 1. Propose/design a VPN for the scenario given below including LAN and WAN settings. 2. Configure and implement the network at low-level design, this part should be done using BOSON NETSIM Simulator. Contents must include: High-level network design summary Solution Design i. Network Topologies ii. IP addressing iii. Configuration details and screenshots to present low-level design iv. Verification methodologies and evaluation analysis Scenario In this scenario, Sigma, Inc. wants to establish a VPN between the subnets of its Human Resources and Finance departments through a system models which does not have any firewall deployed at either end. Both systems will act as VPN gateways. In terms of VPN configurations, a gateway performs key management and applies IPSec to the data that flows through the tunnel. The gateways are not the data endpoints of the connection. The objectives of this scenario are as follows: ? The VPN must protect all data traffic between the Human Resources department’s subnet and the Finance department’s subnet. ? Data traffic does not require VPN protection once it reaches either of the department’s subnets. ? All clients and hosts on each network have full access to the other’s network, including all applications. ? The gateway systems can communicate with each other and access each other’s applications.
