This assignment consists of two (2) sections: an infrastructure docume

This assignment consists of two (2) sections: an infrastructure document and a revised Gantt chart or project plan. You must submit both sections as separate files for the completion of this assignment. Label each file name according to the section of the assignment it is written for. Additionally, you may create and/or assume all necessary assumptions needed for the completion of this assignment. The infrastructure which encompasses the network solution and security considerations is a major consideration for your company.

Considering that the company will be expanding from one (1) floor to three (3) floors in the very near future, you, as the CIO, are responsible for the design of the infrastructure and security protocols. You have been tasked with designing a network that is stable, redundant, and scalable. In addition, speed and reliability are important considerations. Assumptions should be drawn regarding network usage in relationship to network services and resources. All the established criteria that were set at the onset should be adhered to within your plan.

The network solution that is chosen should support the conceived information system and allow for scalability. The network infrastructure will support organizational operations; therefore, a pictorial view of workstations, servers, routers, bridges, gateways, and access points should be used. In addition, access paths for Internet access should be depicted. Additionally, the security of the network should be in the forefront of your design because protecting your data is a primary consideration.

Section 1: Infrastructure Document 1.

Write a four to six (4-6) page infrastructure document in which you:

  • Justify and support the relationship between infrastructure and security as it relates to this data-collection and analysis company.
  • Present the rationale for the logical and physical topographical layout of the planned network.
  • Design a logical and physical topographical layout of the current and planned network through the use of graphical tools in Microsoft Word or Visio, or an open source alternative such as Dia. Note: The graphically depicted solution is not included in the required page length.
  • Illustrate the possible placement of servers including access paths to the Internet, intrusion detection systems (IDS), and firewalls. Note: Facility limitations, workstations, databases, printers, routers, switches, bridges, and access points should be considered in the illustration.
  • Create and describe a comprehensive security policy for this data-

Introduction

The rapid expansion of organizations necessitates a robust and scalable network infrastructure that aligns with organizational goals of security, speed, and reliability. This paper discusses the detailed planning and rationale behind designing an infrastructure for a data-collection and analysis company expanding from a single floor to three floors. The importance of integrating security protocols within the infrastructure commands a comprehensive approach that ensures data integrity, confidentiality, and availability.

Relationship Between Infrastructure and Security

In contemporary organizational environments, infrastructure and security are inherently interconnected. For this data-centric company, the infrastructural foundation—comprising hardware topology, network architecture, and access points—serves as the primary line of defense against potential threats. Security measures such as firewalls, intrusion detection systems (IDS), and secure access points are embedded into the physical and logical design to protect sensitive data from unauthorized access and cyber-attacks (Rouse, 2020). Furthermore, scalable infrastructure ensures that security protocols evolve commensurately with organizational growth, maintaining resilience against emerging threats (Chen et al., 2019).

Rationale for the Topographical Layout

The physical and logical topographical layout considers the geographical distribution of workstations, servers, and networking devices across three floors. A resilient layout employs redundant pathways and centralized servers to optimize performance and fault tolerance. The physical layout positions core network devices—such as routers, switches, and firewalls—in a secure central location, ensuring ease of maintenance and security. Logical layout diagrams illustrate network segmentation, data flow, and access points, helping to visualize data movement between workstations, servers, and the internet (Kumar & Singh, 2018).

Graphical Design of Network Topology

The network topology includes a core switch connecting to distribution switches on each floor, with workstations and printers connected via Ethernet in each area. Servers, including web, database, and application servers, are housed in a secure server room with environmental controls. Internet access is routed through a perimeter firewall with an IDS positioned inline to monitor traffic. Wireless access points are distributed strategically across floors for mobility, secured via WPA2 Enterprise encryption. Logical diagrams in Visio depict these arrangements, emphasizing network segmentation for sensitive data and operational data (Fitzgerald & Dennis, 2020).

Placement of Security Devices and Internet Access Paths

Placement of firewalls at the network perimeter ensures only authorized traffic enters and exits the network. IDS devices are placed strategically within internal segments to monitor suspicious activity. Access paths to the internet are secured via NAT and proxy servers, with redundancy to support high availability. The physical layout considers facility limitations, enabling secure cabling and ventilation in hardware locations. Segregating the internal network from external access points via DMZs enhances security and limits exposure of critical resources (Olsen, 2021).

Security Policy

The security policy mandates strict authentication mechanisms, including 2-factor authentication for administrative access. Data encryption protocols, both at rest and in transit, are enforced across all systems. Regular vulnerability assessments and intrusion detection activities are mandated, with incident response procedures clearly outlined. Access controls are role-based, limiting user privileges based on job requirements. Physical security measures, such as biometric access to server rooms, complement the technical safeguards to prevent unauthorized physical access.

Conclusion

The proposed infrastructure, integrating redundancy, scalability, and security, aims to meet organizational growth needs while safeguarding sensitive data. By aligning network topology with security policies, the company ensures that its data collection and analysis functions are supported by a resilient and protected network environment.
