Network Design


Secure network design is a critical component for protecting resources, processes, and business continuity. Effective network design involves evaluating existing network problems and potential threats, considering secure architectures based on industry best practices and secure design principles, and proposing secure network design solutions that address the business needs of the organization.


Company A is a property and casualty insurer underwriting multiple types of insurance. Company A is acquiring Company B, a financial services organization, in order to diversify and increase market share. Company B conducts business in the same geographical area as Company A and delivers business and individual financial planning services. Both companies provide services from their respective offices and at the customer’s site. Both companies use broadband connectivity.

You are the IT director for Company A and will be the chief information officer (CIO) for the merged organization. You are tasked with analyzing, designing, and presenting the proposed IT integration project. Company A has clear IT infrastructure documentation, including a logical diagram, an organizational chart, and a recent security risk analysis. Company B does not have any IT infrastructure documentation, and several security and integration issues are evident. Company B outsources any IT-related needs to a consultant. Leadership for the merged organization has allocated a limited budget of $35,000 for this project and will expect justification for recommended expenditures.

Integration project requirements include following secure network design principles, selecting or repurposing secure network components, assuring secure communication channels, addressing relevant regulatory compliance, minimizing potential network problems and security threats, delivering integration cost savings, and aligning IT to meet the business needs of the post-merger organization. This post-merger organization will reflect one corporate office and a branch office.


Existing Network Architecture

A.  Describe the network problems Company A has with infrastructure and network security using details from the attached “Company A Organizational Chart,” “Company A Risk Analysis,” and “Company A Visio Diagram.”

Proposed Network Infrastructure Plan

D.  Propose a network topology diagram using Microsoft Visio that represents the merging requirements of Company A and Company B and would remediate all existing infrastructure issues.

E.  Justify the retention or deletion of existing components, and the possible addition of new components as suggested in your proposed network topology diagram, including how each component’s retention, deletion, or addition addresses both security and budgetary concerns included in the scenario.

Network Architecture Summary

F.  Explain how you included secure network design principles in the proposed network topology diagram, including specific examples where these principles are applied.

G.  Explain how you integrated secure hardware components into the proposed network topology diagram to address the needs of the merged organization.

H.  Explain how you implemented secure communication channels for various communication types in the proposed network topology diagram.

I.  Explain how the proposed network topology diagram addresses relevant regulatory compliance requirements for the merged organization.

J.  Summarize security threats and potential network problems that would become a risk as part of the implementation of the proposed network topology diagram and how those problems should be managed or mitigated.

K.  Acknowledge sources, using in-text citations and references, for content that is quoted, paraphrased, or summarized.

L.  Demonstrate professional communication in the content and presentation of your submission.
