Project Deliverable 5: Network Infrastructure And Security ✓ Solved

Project Deliverable 5 Network Infrastructure And Securitythis Assignm

This assignment consists of two sections: an infrastructure document and a revised project plan. You must submit both sections as separate files, titled accordingly. The assignment requires presenting a network infrastructure and security policy to support organizational development and growth, considering scalability, virtualization, and cloud technologies, and including a pictorial view of network components and access paths. A narrative explanation of the network nodes and design rationale is also necessary. Additionally, create a security policy based on the CIA Triad addressing confidentiality, integrity, and availability, as well as ethical considerations related to employee and contractor behavior, password usage, and access controls.

The infrastructure document should be 5-10 pages, identifying potential vulnerabilities and security measures, designing logical and physical network layouts with diagrams, illustrating server placement, access points, firewalls, and other components considering facility limitations. The security policy must protect infrastructure assets adhering to CIA principles and ethical standards. Formatting requirements include double spacing, Times New Roman font size 12, one-inch margins, with APA or school-specific citations and references, along with diagrams included as appendices with proper in-text references.

For the revised project plan, use Microsoft Project to update the plan from Deliverable 4 by adding 3-5 new tasks, each with 5-10 subtasks, emphasizing process improvement and strategic IT initiatives. Submit as separate files with clearly labeled names, ensuring organized presentation.

Introduction

Developing a robust network infrastructure coupled with comprehensive security policies is essential for supporting organizational growth, especially when integrating with international partners. This paper delineates the design process, security considerations, and strategic planning necessary for a scalable and secure network environment, emphasizing virtualization and cloud technologies.

Network Infrastructure Vulnerabilities and Security Measures

Identifying vulnerabilities such as unauthorized access, data interception, malware threats, and virtualization-specific risks is paramount. For instance, virtual machines can introduce hypervisor vulnerabilities if not correctly managed (Hassan et al., 2020). Implementing robust firewalls, intrusion detection systems (IDS), multi-factor authentication (MFA), and secure virtualization practices help mitigate these threats. Cloud computing also presents unique challenges, requiring encryption, secure API access, and compliance with standards like GDPR and HIPAA (Rodrigues & Oliveira, 2021).

Design of the Network Topology

Using diagramming tools like Visio, a physical and logical network topology is designed. The layout includes core routers connected to multiple switches, which branch out to workstations, servers, printers, and wireless access points. Firewalls are strategically placed at network perimeters, and demilitarized zones (DMZ) host internet-facing servers such as web and email servers. Virtualization is incorporated through virtual servers hosted on centralized data centers with secure access controls.

The physical layout considers facility limitations, ensuring optimal placement of hardware for accessibility and maintenance. The logical diagram depicts data flow, security zones, and access paths to the internet, highlighting network segmentation for enhanced security.

Server Placement and Access Paths

Servers are positioned within secured data centers, employing redundant power supplies and cooling mechanisms. Access paths to the internet pass through firewalls, with intrusion prevention systems monitoring traffic. Internal servers are segmented by VLANs to limit lateral movement of potential threats. Network devices such as routers, switches, and access points are configured to optimize throughput and security.

Security Policy Based on the CIA Triad

The security policy emphasizes confidentiality through encryption and access controls, ensuring that sensitive information is only accessible to authorized personnel. Integrity is maintained through regular audits, data validation, and secure update procedures. Availability is ensured through redundant systems, backup solutions, and disaster recovery plans. Ethical standards reinforce responsible employee behavior, including strong password policies, routine security training, and contractor screening.

This comprehensive approach provides a resilient, scalable, and secure network infrastructure aligned with strategic organizational goals.

Conclusion

Designing an effective network infrastructure demands meticulous planning, vulnerability mitigation, and clear security policies rooted in fundamental principles. The integration of virtualization and cloud technology necessitates specific security controls, ensuring the network can support both current operations and future growth. The outlined diagrammatic layout and policies serve as foundational components for a trusted computing environment.
