You Will Be Assigned A Corporation From The Company Profiles Website

Create a network diagram for a selected corporation from the "Company Profiles" website, which includes separate subnets for all major departments. The diagram should account for all workstations, printers, and servers within each subnet, considering future company growth. Each subnet must be labeled with both IPv4 and IPv6 network addresses. Include inside and outside addresses for each router. Additionally, ensure manufacturing systems are segmented from the rest of the network with a separate router and VLAN to maintain proper air-gapping. Use an online diagramming tool such as Creately if Microsoft Visio is unavailable. Link to your specific company profile as instructed by your course materials.

Introduction

The development of a comprehensive network architecture is vital for the effective management and security of organizational information systems. This paper presents a detailed network diagram for a corporation sourced from the "Company Profiles" website, emphasizing departmental segmentation, IP addressing, and security measures such as air-gapping manufacturing systems. The goal is to illustrate an efficient, scalable, and secure network infrastructure adaptable to organizational growth.

Understanding Corporate Network Needs

A corporation's network must support various operational functions, including administrative activities, research and development, manufacturing processes, and customer interactions. Each of these departments has unique requirements regarding bandwidth, security, and scalability. Proper segmentation through subnetting enhances security, performance, and manageability. Additionally, considering future growth ensures the network remains robust and adaptable, avoiding costly redesigns.

Designing the Network Topology

The network design begins by identifying major departments within the company: Administration, Human Resources, Research and Development, Manufacturing, and Customer Service. Each department is assigned a separate subnet to ensure logical separation and security. The corporate office connects through a central router, which interfaces with department-specific routers and switches, facilitating internal communication and internet access.

For manufacturing systems, additional security measures are necessary due to their critical and sensitive nature. An air-gapped VLAN with a dedicated router ensures these systems are isolated from the rest of the network, reducing risks related to cyber threats. The diagram illustrates this separation clearly, with specialized routing paths and VLAN configurations.

IP Addressing Strategy

Each subnet is assigned distinct IPv4 and IPv6 addresses. For example, the Administration department might receive an IPv4 subnet such as 192.168.10.0/24 and an IPv6 prefix like 2001:0db8:10::/64. Similar addressing schemes are adopted for other departments, scaling according to their size and anticipated growth.

Inside addresses (private IPs within subnets) are used for internal communication, while outside addresses are assigned to each router interface for external connectivity. Proper NAT (Network Address Translation) configurations enable secure internet access, masking internal addresses as needed.

Implementing Security Measures

Security is prioritized by segmenting the network, employing VLANs, and configuring firewalls at strategic points, especially at departmental boundaries and the manufacturing air-gapped VLAN. The router configurations include access control lists (ACLs) to restrict traffic between VLANs, permitting only authorized data flows. The manufacturing VLAN remains isolated, with no direct access from other corporate segments, thus ensuring the air gap.

Diagram Representation

The visual network diagram depicts all subnets, routers, VLANs, and IP addresses. Each subnet is clearly labeled with its IPv4 and IPv6 network addresses. The routers display both inside (private) and outside (public) addresses, showing the flow of data between internal networks and external networks. Manufacturing systems are linked via a dedicated VLAN and router, isolated from the main corporate network.

Conclusion

Designing a secure, scalable, and efficient corporate network requires meticulous planning. By segmenting networks based on departmental functions, applying proper IP addressing schemes, and implementing security measures like air-gapping manufacturing systems, organizations can enhance operational security and flexibility. The proposed diagram serves as a blueprint for deploying a resilient network architecture capable of supporting current operations and future expansion.
