Project Network Design And Planning Purpose ✓ Solved
Project Network Design And Plan Purpose This project
This project provides you an opportunity to solve a comprehensive problem in firewall and virtual private network (VPN) implementation at various levels. You will play the role of an employee participating in network design and planning of a specific business situation.
Overall Project Scenario: Corporation Techs provides remote and on-site support to small and mid-size businesses. Clients use Corporation Techs’ services to solve problems involving malware removal, to manage data recovery and network issues, and to install hardware and software. Due to recent developments, most technical representatives will begin working from home within the next six months. Because Corporation Techs provides 24/7 support, its systems and communications pathways must be fully operational at all times. In addition, the company has been experiencing unprecedented growth and is preparing to double its client-facing staff.
You are a junior network architect who is responsible for helping to plan and design network enhancements to create a more secure internal network, and to ensure secure remote access.
Tasks for Project Part 1: Conduct research to determine the best network design to ensure security of internal access while retaining public website availability. Design a network configuration with physical and logical topologies. Identify major network elements (e.g., servers, switches, gateways) and their locations within the private and protected network segments. Include a high-level plan that ensures communications are available 24/7. Recommend whether to continue using IPv4 or upgrade to IPv6, and explain why. Create a basic network diagram that illustrates the current network and enhancements. Create a draft report detailing all information as supportive documentation.
For Project Part 2: Research and select firewalls for the Corporation Techs network. Describe each firewall, why you selected it, and where it should be placed for maximum effectiveness. Address network, server, and workstation firewalls. Describe a plan for creating a DMZ, and explain how it makes the network more secure. Research network authentication and create a high-level plan for secure authentication to internal network resources. Create a draft report detailing all information as supportive documentation.
For Project Part 3: Research and recommend the most appropriate VPN technology. Describe the VPN technology and explain why it is the best choice for Corporation Techs. Recommend any other forms of remote access that are relevant and describe how they would be used. Create a draft report detailing all information as supportive documentation.
For Project Part 4: Create a final network diagram that includes the basic diagram and all relevant network enhancements. Create a professional report that includes content from each draft report. Include details for all relevant information, persuasive justification for your recommendations, and methods to measure the success of each major network enhancement. Include a 1- to 2-page executive summary. Use simple, clear language that primary stakeholders (non-IT) can understand easily.
Paper For Above Instructions
The role of network design and planning is critical to ensure the security and efficiency of business operations, particularly for a company like Corporation Techs, which is undergoing significant change. As a junior network architect, the task is to create a comprehensive network design that incorporates security measures like firewalls and VPNs for remote access while addressing the pressing needs for scalability and robustness.
Current Network Design
Corporation Techs' current network consists of one public-facing Linux/Apache web server, two application servers, two database servers, two file and print servers, and fifty workstations. This setup, while functional, requires enhancements to ensure secure internal access and improved performance. The existing border firewall protects the network; however, it is essential to assess whether it meets the increased demands of future operations.
Network Configuration Design
The proposed network configuration integrates both physical and logical topologies. The physical topology employs a star configuration where each workstation connects to a central switch, which in turn connects to the internet via the border firewall. The logical topology segments the network into departments, particularly separating the Accounting and Sales functions to mitigate risks related to data breaches.
Major network elements include:
- 1 Linux Web Server
- 2 Application Servers running Windows Server
- 2 Database Servers running Windows Server
- 2 File and Print Servers running Windows Server
- 50 Workstations running Microsoft Windows
To ensure 24/7 communications availability, redundant communication pathways will be established by implementing additional switches and utilizing failover mechanisms in server configurations. The recommendation is to maintain the use of IPv4 for the time being, as it continues to serve the organization's needs while allowing gradual planning for migration to IPv6.
Firewall Selection and Placement
Moving forward with firewall implementation, I recommend deploying a next-generation firewall (NGFW) for enhanced security. This firewall can be strategically placed to create a Demilitarized Zone (DMZ), which strengthens the network perimeter. The NGFW will remain at the network's edge, ensuring that both internal networks and DMZ are monitored and protected against external threats. Additionally, individual server firewalls can be deployed on the application and database servers to add layers of security.
Remote Access and VPN Implementation
The adoption of a virtual private network (VPN) is critical for secure remote access. Internet Protocol Security (IPSec) VPN will be the best choice for Corporation Techs, as it provides robust encryption for data in transit, ensuring confidentiality and integrity. SSL/TLS VPNs could also be recommended for their compatibility with existing web-based tools.
In addition to VPNs, implementing secure remote desktop services will facilitate access for employees working from home effectively while maintaining strict authentication measures to prevent unauthorized access.
Final Network Design Report Overview
The final network design report will encompass an executive summary detailing the objectives behind the network enhancements, backed by data supporting the recommendations. The final network diagram will illustrate all functionalities, including the positioning of firewalls, servers, and overall network structure. Each aspect will be documented clearly, allowing for easy comprehension by stakeholders regardless of their technical expertise.
Conclusion
This project not only emphasizes the importance of security in network design but sheds light on the need for a flexible structure that can adapt to the needs of a growing company. By undertaking these initiatives collectively, Corporation Techs can ensure that it maintains secure and efficient network operations while ultimately supporting its business ambitions.
