Recommend And Explain A Design Solution For Hospital Network

Recommend and explain a design solution for hospital network security and access

You are the lead engineer for Trades Networking Group (TNG), a small consulting firm located in the Southeast United States. You and a team of engineers were contracted to develop and deploy a network for a hospital in the South Florida area. The network will host Internet-facing servers and an e-mail server. Web-based services will be used to interact with a database that holds patient records. However, this database will not be available from the Internet. It will be available only from the intranet. Not all users on the hospital's network should be able to reach that internal Web-based customer database server. Wireless solutions must be deployed throughout the hospital; however, guests should not be able to access the corporate data highway. Working with your group of engineers, complete the following: Recommend and explain a design solution. Explain why you have chosen your design. The document of 3–5 pages should be a professional design document. You must include a diagram in your document to depict your recommended design. Create a 6-slide PowerPoint presentation to present to your customers when you make your design presentation. APA Format, References required, Abstract page required.

Introduction

The healthcare sector demands a robust, secure, and efficient network infrastructure to ensure the confidentiality, integrity, and availability of sensitive patient data. Designing a network for a hospital in South Florida requires a strategic approach that balances accessibility for authorized personnel and security against unauthorized access, especially given the deployment of wireless solutions across the facility. This paper presents a comprehensive network design, including segmentation, security controls, wireless architecture, and access policies that meet these healthcare-specific needs.

Network Architecture Overview

The proposed network architecture is based on a multi-layered design that segregates internal resources, manages external access, and isolates wireless guests from corporate data. The core components include perimeter security with firewalls, segmented LANs, DMZ for Internet-facing servers, and secure wireless access points. The architecture ensures that internal users can access patient records through web-based services, while limiting external access and guest connectivity to prevent potential breaches.

Segmentation and Access Control

Segmentation is fundamental to this design, achieved through VLANs (Virtual Local Area Networks). VLANs create logical separation between the Internet-facing servers, internal staff, administrative functions, and guest Wi-Fi. The hospital’s internal network comprises:

  • VLAN 1: Internal Staff and Administrative Network
  • VLAN 2: Patient Records Web Server (restricted access)
  • VLAN 3: Guest Wi-Fi

Access controls are implemented via ACLs (Access Control Lists) on Layer 3 switches and firewalls, which restrict traffic flow between VLANs according to role and necessity. For example, only authorized hospital staff have access to the web server hosting patient records from VLAN 1, while Guest VLAN is isolated entirely from internal resources.

Security Measures

Robust security strategies include:

  • Firewall implementation at the network perimeter to monitor and filter incoming/outgoing traffic.
  • Intrusion Detection and Prevention Systems (IDPS) to detect suspicious activities.
  • VPN access for remote hospital staff to securely connect to internal resources.
  • Secure authentication protocols such as WPA3 for wireless networks and RADIUS for user authentication.

These measures ensure that sensitive data remains secure while maintaining operational accessibility.

Wireless Deployment

Wireless access points are deployed throughout the hospital to enable mobility and ease of access. Segments include:

  • Secure, encrypted WLAN for hospital staff with WPA3 and 802.1X authentication.
  • Separate Guest WLAN using WPA3 personal encryption, isolated from internal network via VLAN and firewall rules.

This setup guarantees that guest users cannot access internal hospital systems or the corporate data highway, safeguarding sensitive patient and administrative data while providing necessary wireless connectivity.

Diagram of the Network Design

The network diagram illustrates the segmentation of VLANs, placement of firewalls, wireless access points, and the DMZ hosting Internet-facing servers. The diagram emphasizes the separation between internal resources and wireless guest access, with clear demarcations of security zones.

Justification of Design Choices

The design leverages industry best practices such as network segmentation, layered security, and dedicated wireless solutions to mitigate risks associated with hospital environments. The segregation of VLANs and strict access controls protect patient data, complying with regulations like HIPAA. Using WPA3 and 802.1X ensures secure wireless authentication for staff while isolating guests. Firewalls and IDPS provide oversight and threat detection, reducing vulnerabilities. This comprehensive approach balances security with operational efficiency, ensuring hospital staff and guests can access needed resources without compromising security.

Conclusion

This proposed network design addresses the critical needs of the hospital environment, emphasizing security, compliance, and accessibility. By implementing segmentation, layered security controls, and dedicated wireless networks, the hospital can safeguard sensitive patient data while providing flexible connectivity for staff and guests. The architecture fosters a resilient and scalable environment, adaptable to future technological advancements and regulatory requirements.
