Assume You Are A Consultant To A Local Business That Has Asked You To

Assume you are a consultant to a local business that has asked you to propose an enterprise-wide solution that includes topology, network devices, IP infrastructure, and network security. The scenario is as follows: A small accounting firm, ABC Accounting, Inc., landed a large account a year and a half ago that has already led the company to grow from five employees to 200 employees and expectations to employ 350 within a year’s time. In the face of continuing expansion, ABC plans to add offices in their current building that will span a total of three floors. At least one third of ABC employees have laptops and travel often. All ABC employees have Windows 7 computers, which currently are not connected to each other.

You have been hired as a consultant to provide a detailed technical proposal that recommends a solution that addresses each of the detailed specifications that follow. Your solution regarding each specification should comprise a separate section of the body of your proposal. Topology (type of network) and network devices ABC needs to set up a network and requires clarification regarding the type of network (or topology) in order to properly configure the connections among all PCs within the organization. The company is looking for guidance regarding the type of network devices that will connect the machines together. Brand is not mandated.

The company asks that you explain what internal and external networking components are required (explaining each and justifying WHY you chose the network devices you did). The network must have the capacity to: Connect all users to company resources (e.g, printers, scanners, and other items). Provide file sharing options. Manage these resources in a central location. All proposals should include cost elements.

ABC has asked that you provide details regarding an IP structure (which includes static, DHCP, or the possibility of both, and proper IP Class assignment) that is mindful of the company’s expectation of continued growth. Security Basic security has always been in place and now the company would like you to make this a secure facility to protect against internal and external security threats. Be sure to include details with respect to: Social engineering/internal threats. Firewalls/switches. VPN’s. Authentication. Security protocols. Vulnerability assessment. Your draft proposal should include each of the following sections, with each preceded by an appropriate heading: Introduction/overview Table of Contents Body, including a separate section for each numbered item in the specifications above Conclusion APA References Any appendices you feel appropriate All Academic papers should include a cover page with your name, date, school name, section, course name, and instructor name. Support each of your four proposed elements by citing at least one credible source, which may be as per the assignment guidelines.

Introduction and Overview

The rapid growth of ABC Accounting, Inc., from a small firm with five employees to a substantial enterprise with over 200 staff, necessitates a comprehensive overhaul of its current network infrastructure. As the organization expands into multiple floors within their building, and considering that a significant portion of staff are mobile and rely on laptops, a resilient, scalable, and secure network architecture is imperative. This proposal outlines an enterprise-wide solution encompassing network topology, devices, IP infrastructure, and security measures, designed to support growth, facilitate resource sharing, and ensure robust security against internal and external threats.

1. Network Topology and Devices

The network topology for ABC Accounting must accommodate both wired and wireless connections across three floors, supporting a large number of users and devices. A hybrid topology combining star and wireless (Wi-Fi) elements is most appropriate. The core of the wired network should be a star topology, with switches connecting all floors through high-capacity routers that serve as the central hub. Wireless access points (WAPs) will extend connectivity to mobile devices and laptops, which constitute about one-third of the workforce.

Core network devices should include managed switches, which provide control over traffic and enable VLAN segmentation for security and administrative purposes. High-speed routers will connect the internal network to the Internet, providing necessary security features like NAT and firewall capabilities.

External components include a perimeter firewall to safeguard against outside threats, VPN gateways to enable remote secure access, and possibly an IDS/IPS system to monitor for suspicious activity. The use of enterprise-grade devices ensures reliability, scalability, and security, with brands like Cisco, Juniper, or HPE being suitable options.

2. IP Infrastructure Design

The growth projection and mobility of employees call for a flexible IP addressing scheme. A combination of DHCP for dynamic address allocation and static IPs for servers and network infrastructure devices enhances management. Class B IP address allocation (e.g., 172.16.0.0/12) supports ample IP addresses while maintaining control and security.

DHCP servers should be configured to assign IP addresses within specific ranges per floor or VLAN. This allows logical segmentation, easier troubleshooting, and efficient management. Subnetting each floor separately simplifies network management and enhances security by isolating traffic where necessary. For example, VLANs per floor can use subnets like 172.16.1.0/24, 172.16.2.0/24, and 172.16.3.0/24.

3. Network Security Framework

Security is critical given the sensitivity of financial data and the mobility of users. The security plan should address internal threats like social engineering and external threats including hacking attempts and malware.

• Social Engineering/Internal Threats: Educating employees about phishing, suspicious emails, and secure password practices reduces internal risks.
• Firewalls and Switches: Deploying hardware firewalls at the perimeter, complemented by internal managed switches supporting VLANs and port security features, barricades external access and contains internal threats.
• VPNs: Implementing VPN solutions enables secure remote access, encrypting the data transmitted over public networks.
• Authentication and Protocols: Enforcing multi-factor authentication (MFA), employing WPA3 for wireless security, and using SSL/TLS protocols for data transmission significantly bolster security.
• Vulnerability Assessments: Regular scans and penetration testing to identify weaknesses proactively mitigate potential breaches.

Conclusion

In conclusion, the proposed network architecture for ABC Accounting balances scalability, resource sharing, and security. The hybrid topology with star and wireless components supports current and future growth. Implementing a layered security approach, appropriate IP configuration, and high-quality network devices lays a resilient foundation capable of handling increasing demands while protecting sensitive financial data. This comprehensive plan positions ABC Accounting for continuous success and secure expansion.
