- 1. Narrative Descriptions of Network Diagrams CYB/360 Version 1 1 Narrative Description of Network Diagrams for International Plastics Inc. International Plastics Inc. Corporate Headquarters a) The network diagram for the corporate headquarters is really a composite of a number of sections: Note the backbone base for this location is 100baseT i) The administration section. Displays the main operational functions: Corporate, HR, etc. with a computer icon that defines the current number of employees in that function, and a description of the computer. There are 36 VOIP telephones in this section. ii) The R&D function, which has 1000baseF network backbone and is totally a MAC based environment. There are 15 employees each with their computers; the section includes 3 high-end color printers and a plotter. The 1000baseF network is connected to the corporate LAN through a switch. iii) The servers and an NAS. The servers include WIN server, a WIN Exchange server, a UNIX server, which hosts the corporate SAP ERP SW. All the servers are IBM servers: the WIN servers are IBM HS20 blade servers and the main UNIX server is an IBM p series. iv) An UPS is provided to prove backup power for the server room. v) The last section is the communications environment, which has two main parts: the data link to the Satellite base station

The second part of the communications environment is a router to provide a T3 connection through a firewall to the outside network. Copyright © 2017 by University of Phoenix. All rights reserved.

- 4. The WLAN environment is configured for static addressing. Since it is a standard procedure that networking devices take the last host address in a network, this makes them targets of network-based cyber-attacks. Since the entire network is built on a static configuration, each device needs to be set accordingly lest communication is hampered in the case of a misconfiguration. The network only implements network security only between the data center and the internal network. This means that an insider attack where malicious code is introduced in one of the computing terminals is rapidly spread if it manages to bypass antimalware programs on the computers (Ghelani, Maral & Mehetre, 2019). This framework is thus susceptible to a wide range of vulnerabilities based on the configuration imposed. References Ghelani, D., Maral, V., & Mehetre, D. C. (2019).
