Project Deliverable 5 Infrastructure And Securitythis Assignment Co

Write a four pages 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.

Paper For Above instruction

The development of a robust and scalable network infrastructure, intertwined with a comprehensive security policy, is essential for a data-collection and analysis company aiming to operate efficiently across multiple floors. As the Chief Information Officer (CIO), designing such an environment involves a careful balance of technical specifications, organizational needs, and security considerations. This paper articulates the rationale behind the infrastructure and security measures necessary to support future expansion, current organizational demands, and safeguarding of sensitive information.

Relationship Between Infrastructure and Security

In contemporary information systems, infrastructure and security are inherently interconnected. A well-designed infrastructure lays the foundation for effective security measures, ensuring clear data flows and control points while enabling the implementation of security protocols such as firewalls, intrusion detection systems (IDS), and access controls. In a data-collection and analysis enterprise, the confidentiality of data and its integrity during collection, processing, and dissemination are paramount (Kim & Solomon, 2016). Consequently, infrastructure design must embed security considerations into every layer, from physical hardware to logical network topology.

Security objectives hinge on the infrastructure supporting confidentiality, integrity, and availability (CIA) of data. For instance, redundant network pathways mitigate downtime, enhancing availability, while geographically distributed servers ensure data integrity and backup resilience. Physical security controls—such as restricted server room access—prevent unauthorized physical access, which is a critical layer within the overall security architecture. Therefore, infrastructure decisions directly influence security effectiveness, emphasizing the need for integrated planning (Gordon & Loeb, 2019).

Rationale for Logical and Physical Topographical Layout

The company's future expansion from one to three floors necessitates a hierarchical, scalable network topology that ensures stability, redundancy, and speed. The physical layout involves strategic placement of core network components—servers, switches, routers, firewalls, IDS, and access points—that optimize performance and security. The logical topology is designed to facilitate seamless communication between workstations, servers, and external resources while isolating sensitive components to minimize threat surfaces.

The core network fabric connects all floors via high-speed switches, with each floor hosting multiple workstations and departmental servers. Critical infrastructure components like the main firewall and IDS are housed in a secure server room centrally located to facilitate monitoring. Internet access is routed through dedicated gateways with layered security controls, including firewalls and intrusion detection systems, positioned at network perimeters. Segmentation of the network into subnetworks (VLANs) for different departments improves security and performance.

Graphical Layout Design

A detailed layered network diagram illustrates the planned topology, including workstations, servers, routers, bridges, gateways, switches, access points, and security devices. The diagram emphasizes redundancy through dual uplinks and backup power supplies, ensuring high availability. Internet access paths are depicted with firewalls and IDS interposed between the external network and internal resources. Facility limitations power the placement of physically secure hardware, while open areas accommodate access points for wireless connectivity.

Placement of Servers and Security Devices

Servers supporting core functions—database servers, application servers, and file servers—are centralized within a secure, climate-controlled server room. Access paths bifurcate into internal network segments and external links. Firewalls serve as first-line defense, regulating inbound and outbound traffic, with intrusion detection systems monitoring ongoing activity for anomalies. DMZ (demilitarized zones) are used to host public-facing services such as web servers, isolated from the internal network to reduce potential breach impact.

Security Policy for Data-Collection and Analysis Company

The security policy encompasses measures aligned with the CIA triad, emphasizing confidentiality, integrity, and availability. Confidentiality is maintained through encrypted communications, role-based access controls, and secure authentication methods. Data integrity is protected via checksum mechanisms, audit logs, and digital signatures, ensuring data remains unaltered during transmission and storage. System availability is promoted through redundancy, regular backups, and disaster recovery planning.

Ethically, the company mandates strict policies on employee behavior and contractor access. Password protocols require complexity, periodic changes, and multi-factor authentication. Access to sensitive data is granted based on necessity, with layered permissions to prevent unauthorized exposure. Employees and contractors are trained in security awareness to foster a security-conscious culture, and compliance is enforced through monitoring and audit procedures (Whitman & Mattord, 2018).

Conclusion

Integrating infrastructure planning with security policies creates a resilient framework capable of supporting organizational growth while protecting critical assets. The proposed layout addresses current needs and anticipates future scaling, guaranteeing that speed, reliability, and security are maintained. As the organization expands from one to three floors, the scalable, secure, and redundant network infrastructure will serve as a backbone for efficient data collection, analysis, and dissemination, aligned with organizational policies and ethical standards.
