Project Deliverable 5: Network Infrastructure And Sec 171124

Project Deliverable 5 Network Infrastructure And Securitydue Week 8 A

This assignment consists of two sections: an infrastructure document and a revised project plan. You must submit both sections as separate files, labeled accordingly. Present the network infrastructure and security policy that will support the organization’s growth, ensuring the chosen network solution supports the information system and allows for scalability. Include a graphical view of workstations, servers, routers, bridges, gateways, access points, and consider virtualization and cloud technology due to the multinational merger. Depict internet access paths. Include a narrative explaining all network nodes and the design rationale. Using the CIA Triangle, define the organizational security policy.

Paper For Above instruction

The development of a robust and scalable network infrastructure is fundamental for supporting an organization’s operational efficiency and future growth, especially in the context of integrating with a multinational partner. This paper delineates the planning, design, security measures, and policy frameworks essential for establishing a secure, flexible, and efficient network infrastructure compliant with organizational goals.

Network Infrastructure Vulnerabilities and Security Measures

Identifying potential vulnerabilities within network infrastructure is a critical step toward safeguarding organizational assets. Common vulnerabilities include unauthorized access, data interception, malware attacks, and insider threats. For instance, unpatched systems and outdated firmware on network devices could expose the system to exploits. Additionally, inadequate security controls on wireless networks may render them susceptible to eavesdropping and unauthorized access.

Mitigating these vulnerabilities requires layered security strategies. Firewalls, intrusion detection and prevention systems (IDS/IPS), and access controls should be implemented to prevent unauthorized intrusion. Regular patch management and system updates minimize exploitation risks. Encrypted communications, especially for remote and cloud access, are essential. Moreover, network segmentation limits lateral movement during security breaches, reducing potential damage.

Incorporating Virtualization and Cloud Technologies

Given the multinational merger context, virtualization and cloud computing are vital to enhance scalability and flexibility. Virtualization consolidates servers, reducing physical hardware footprint and enabling rapid provisioning of resources. Cloud technology facilitates remote access, disaster recovery, and collaboration among dispersed teams. Security controls such as cloud access security broker (CASB) solutions, strong identity and access management (IAM), and encrypted connections are crucial to protect cloud environments.

Logical and Physical Network Topology Design

The physical topology involves a data center hosting core servers, connected via high-speed switches to departmental workstations, printers, and peripheral devices. Routers and firewalls demarcate security zones and provide Internet gateways. Wireless access points (APs) are strategically positioned for mobility within office spaces. The layout considers facility constraints, including space for hardware deployment and cable runs.

The logical topology describes the virtual segmentation of the network, including virtual LANs (VLANs) for departments, virtual servers, and cloud-based resources. Virtualization technology enables creation of isolated environments, reducing security risks. Cloud services are integrated through secure, encrypted tunnels—virtual private networks (VPNs)—linking on-premises infrastructure with cloud providers.

Diagram and Placement of Network Nodes

A graphical diagram, created via Visio or Dia, illustrates the placement of servers—application, database, and backup—in the data center, with redundant Internet firewalls. The diagram shows computer workstations within departments, connected through switches, and wireless access points for mobile users. Internet access paths include firewalls for perimeter security, with DMZ zones hosting public-facing servers (e.g., web servers) to segregate internal and external traffic.

Security Policy Based on CIA Principles

The organizational security policy adopts the CIA triad—Confidentiality, Integrity, and Availability—to safeguard information assets:

• Confidentiality: Implementation of encryption protocols (e.g., TLS, VPNs), access controls, and employee training ensures sensitive data remains confidential. Role-based access control (RBAC) limits data access to authorized personnel.
• Integrity: Use of checksum mechanisms, audit logs, and digital signatures maintain data accuracy and integrity. Regular data validation processes are instituted.
• Availability: Redundant hardware, disaster recovery plans, and continuous monitoring systems guarantee system availability. Maintenance windows are scheduled to prevent service disruptions.

Ethical Considerations and Employee Policies

Ethical behavior is integral to network security. Policies should clearly define acceptable use of company resources, including restrictions on personal activity, social media, and software installation. Password policies mandate strong, unique passwords and regular updates. Multi-factor authentication (MFA) adds another security layer. Contractors and remote employees must adhere to security protocols, with access granted based on necessity and regularly reviewed. Training programs foster awareness of ethical issues and security best practices.

Conclusion

A comprehensive network infrastructure, designed with security and scalability in mind, is essential for supporting the organizational operations and growth objectives. By integrating virtualization and cloud technologies, implementing layered security measures aligned with CIA principles, and fostering an ethical security culture, the organization can achieve a resilient and flexible network environment poised for future expansion.
