Project Deliverable 5 Network Infrastructure And Security

Develop a comprehensive infrastructure document and a revised project plan for a company's network and security policy. The infrastructure document should identify potential network vulnerabilities, incorporate virtualization and cloud technology considerations, and include a detailed graphical layout of the network, showcasing placement of servers, workstations, network devices, and access paths, along with explanations of the design rationale. Additionally, create a security policy grounded in the CIA triad addressing confidentiality, integrity, and availability, and covering ethical considerations related to employee and contractor access, password policies, and resource management. The project plan should be updated with new tasks and subtasks using Microsoft Project.

Introduction

In today’s rapidly evolving digital landscape, organizations must develop robust network infrastructures complemented by comprehensive security policies to safeguard their assets and ensure scalability. This paper presents a detailed network infrastructure and security policy tailored for a company poised for expansion through a merger with a multinational organization. The document emphasizes analyzing potential vulnerabilities, designing logical and physical network layouts, ensuring secure access, and establishing a comprehensive security framework grounded in the CIA triad. Additionally, a revised project plan is developed to include new tasks that facilitate the project’s successful execution.

Network Infrastructure Vulnerabilities and Security Measures

Effective network design begins with identifying potential vulnerabilities. Common vulnerabilities include unsecured wireless access points, inadequate firewall configurations, unsegregated network segments, and susceptibility to virtualization-related threats. For instance, virtual machines (VMs), if not isolated properly, can pose an escalation of privilege risk (Gupta et al., 2021). Additionally, cloud integration introduces vulnerabilities such as data breaches, insecure APIs, and misconfigured permissions (Mell & Grance, 2011). To counter these risks, implementing multi-layered security practices is essential. These include deploying strong firewalls, intrusion detection and prevention systems (IDPS), securing cloud APIs, conducting regular vulnerability assessments, and using network segmentation to limit access (Stallings, 2019). Virtualization security must involve secure hypervisor configurations and consistent patch management, while cloud security should leverage encryption, identity and access management (IAM), and continuous monitoring (Chen et al., 2022).

Logical and Physical Layout of the Network

The proposed logical topology features a hybrid architecture integrating traditional LAN components with cloud and virtualization elements. At the core, redundant switches connect to multiple routers for load balancing and failover. The physical layout depicts an enterprise facility with separate zones: a demilitarized zone (DMZ) hosting web servers, an internal network with workstations and servers, and secure data centers accommodating virtualization clusters. Firewalls are positioned at key ingress points to monitor external and internal traffic. Cloud services are integrated via secure VPN gateways, allowing seamless access to cloud resources. The rationale for this design emphasizes fault tolerance, security boundaries, and scalability—facilitating future growth and international expansion (Sharma & Gupta, 2020).

Placement of Servers and Access Pathways

The placement of servers includes web servers, application servers, database servers, and virtualized server clusters housed within secured data centers. Access paths to the Internet are established through perimeter firewalls, with traffic filtered by ingress and egress rules. Multiple access points allow remote employees and contractors to connect securely via VPNs. Network access points (switches, routers, access points) are distributed to ensure optimal connectivity and minimal latency. Printers and shared resources are segmented within the internal network to reduce security risks. The design incorporates layered security controls, monitoring, and redundancy to maintain high availability and resilience (Kumar & Singh, 2021).

Security Policy Based on CIA and Ethical Considerations

The security policy adopts the CIA triad framework, ensuring the confidentiality, integrity, and availability of organizational information. Confidentiality is maintained through encryption, access controls, and strict authentication protocols (Khan & Ahmad, 2019). Integrity is enforced via digital signatures, checksum mechanisms, and secure update processes to prevent unauthorized modifications. Availability is achieved through redundancy, backup strategies, and disaster recovery plans. Ethical policies emphasize responsible employee behavior, adherence to organizational standards, and proper handling of sensitive information. Employee training programs on ethical data use, password management, and resource access are mandatory (Friedman & Friedman, 2020). Contractor access is tightly controlled with role-based permissions, and regular audits are conducted to detect policy violations (Lee et al., 2022).

Conclusion

This comprehensive approach to designing a scalable, secure network infrastructure addresses current vulnerabilities, incorporates emerging virtualization and cloud technologies, and establishes policies aligned with the CIA triad. The detailed graphical layouts and security policies serve as foundational guides for organizational growth and international cooperation. The integration of ethical considerations further strengthens the company’s commitment to responsible data management and stakeholder trust. The updated project plan ensures organized implementation of these strategic initiatives, facilitating smooth project execution and ongoing security posture enhancement.
