Network Security




Intrusion Detection Systems;Objectives;In this lab, students will examine the following objectives.;Differentiate the use of IDS and IPS to detect network attacks;Design a network with IDS/IPS.;Justify the use of IDS/IPS for a given network solution.;Scenario;A small company is using the topology shown below to secure its intranet while provides a less-secured environment to its eCommerce DMZ server. The company is concerned firewalls are not enough to detect and prevent network attacks. Hence, deployment of sensors to Intrusion detection systems (IDS) and/or intrusion prevention systems (IPS) are needed in the network. Your job is to provide recommendations including a network design with IDS/IPS that meet company?s requirements.;Initial Topology;Company?s Requirements;Detect any malicious traffic entering the ecommerce server without performance penalty to traffic getting in the server from revenue-generating customers.;Stop any malicious traffic entering the human resources LAN (HR LAN).;Detect any malicious traffic entering the computer terminal in the marketing LAN (MKT LAN).;Stop any traffic entering the File Server in MKT LAN.;Deploy a centralized database and analysis console in the intranet to managing and monitoring both, IDS and IPS sensors.;Note: RED text indicates the required questions to answer;Task 1?Layout the New Network Design;Click on the Initial Network Topology link at iLab tab in week 7, and save in your computer the power point file Initial_Network_Topology_iLab7.ppt. This file contains a diagram for the initial network topology and pictures of all components needed to create the new network design.;Review the documentation provided in the references at the end of this instructions, to get more familiar with the implementation of IDS and IPS in network design. You need to find a network solution that meets company?s requirements.;#1. Paste below your new network design diagram.;Task 2?IDS/IPS Recommendations;#2. Write an engineering specification document of at least 250 words (e.g. 1 page of full text, double space & size 12) describing why your networks design meets each of the company?s requirements. Justify how each recommendation addresses the company?s needs.;Task 3? Conclusions;#3. Describe in two paragraphs your learning experience in this lab.
