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

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-collection and analysis company that will: Protect the company infrastructure and assets by applying the principles of confidentiality, integrity, and availability (CIA). Note: CIA is a widely used benchmark for evaluation of information systems security, focusing on the three (3) core goals of confidentiality, integrity, and availability of information. Address ethical aspects related to employee behavior, contractors, password usage, and access to networked resources and information.

Introduction

The rapid expansion of organizational infrastructure requires a strategic approach to network design that ensures stability, security, and scalability. As organizations grow, especially across multiple floors or facilities, the complexity of maintaining an effective and secure network increases substantially. This paper aims to outline a comprehensive infrastructure plan for a data-collection and analysis company expanding from one to three floors. The strategy encompasses logical and physical network layouts, security policies based on the CIA triad, and recommendations for robust security protocols to safeguard organizational data.

Infrastructure and Security Interrelationship

The relationship between infrastructure and security within an organizational context is foundational to safeguarding assets and ensuring operational integrity. Infrastructure elements such as routers, switches, servers, and access points form the backbone of the company's digital operations. Properly designed infrastructure facilitates effective security measures like intrusion detection systems (IDS), firewalls, and access controls. As Kizza (2017) argues, a well-structured network topology inherently supports security by segregating sensitive data, implementing layered defenses, and enabling prompt response to threats.

Furthermore, infrastructure design directly influences security capabilities. For instance, a segmented network topology limits the spread of malware and unauthorized access, while redundant pathways ensure continuous operations during failures or attacks. As the company scales, it's critical that the infrastructure supports dynamic security policies aligned with the CIA principles—confidentiality, integrity, and availability—ensuring data protection while maintaining high system uptime (Stallings, 2019).

Logical and Physical Topographical Layout

The logical layout of a network defines the flow of data, security zones, and interactions among components, whereas the physical layout pertains to actual device placement and cabling. The logical network designed for this organization incorporates multiple security zones: corporate LAN, guest access, and data center subnet. Core components include high-capacity switches, firewalls, IDS, and load balancers placed strategically to optimize traffic flow and security (Odom, 2012).

The physical design considers space limitations, device placement on the floors, and accessibility for maintenance. Servers hosting databases, application services, and management interfaces are housed in secure data rooms with environmental controls. Access points are placed to maximize wireless coverage across all three floors, with wired connections for critical servers and workstations. Internet access pathways are linked via perimeter firewalls with layered security protocols, including DMZ zones for public-facing servers.

Diagrammatic representations (Appendix A) illustrate the planned placement of key infrastructure components such as routers, firewalls, and workstations, highlighting access paths to the internet, IDS placement, and security zones.

Security Policy Framework

A robust security policy based on the CIA principles is crucial in protecting organizational data and systems. Confidentiality is maintained through role-based access controls, encryption, and strict authentication protocols. Access to sensitive data and network resources is limited to authorized personnel, with multi-factor authentication in place (ISO/IEC 27001, 2013).

Integrity is preserved via regular data backups, audit logs, and checksum protocols to detect tampering or unauthorized modifications. Ensuring data accuracy and consistency also involves employing secure transmission protocols like SSL/TLS.

Availability is achieved through redundant network paths, reliable hardware, and proactive security measures such as intrusion detection and prevention systems. Outage prevention strategies include regular patch management, hardware monitoring, and disaster recovery planning.

Addressing ethical considerations involves establishing clear policies for employee conduct, password management, and contractor access. Employees are trained on security awareness, and contractors are subjected to background checks and access limitations (Whitman & Mattord, 2018).

Conclusion

Designing a scalable, secure, and reliable network infrastructure for an expanding organization entails thoughtful planning of physical and logical layouts, security policies rooted in CIA principles, and continuous evaluation of emerging threats. These measures collectively ensure organizational resilience, compliance with best practices, and safeguarding of critical data assets.
