Network Security Analysis

You are in networking at a large international company. Your company recently decided to implement a cross-training initiative and you have been selected to give a presentation to an audience of non-networking professionals working at various departments in your company.

Your presentation must be clear and concise enough to convey technical information to professionals who have a limited understanding of how networking actually works. However, it must also be accurate enough that your audience can understand how their company roles (such as scheduling resource-hogging reports, allowing contractors access to the system, and setting the hours international customers can place orders on your company’s system) can impact the company’s network, particularly in terms of security.

You decide to use the OSI model to explain the fundamental characteristics and components of networks because it is visual and presents the complexity of network communication in 7 layers.

Draft your speaker notes to hand off to an assistant who will turn your notes into a graphic-rich presentation. Each of your answers should be about 150-250 words long.

Note: Your assignment is to draft speaker notes. Do not create a presentation and do not write a paper.

1. Overview of Networking and Security

You decide to begin your presentation by providing your audience an overview of networking, with an emphasis on security and why it is important for all company roles to assist in securing the company’s network.

Discuss the potential security risks for each layer of the OSI model and the risks in each of the following:

·       Distributed vs. centralized computer systems and why your department chose to be distributed/centralized

·       Different network topologies and why your department chose the topology it did

·       Why standards bodies are essential in networking and how your department complies with standards

·       The importance of communication protocols and which one(s) your department chose

·       The differences between LAN, WAN, and wireless technologies, and how your department incorporated each
