Design Solution for Hospital Network Infrastructure

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 patients 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.

Introduction

The healthcare industry demands robust, secure, and reliable network infrastructure to support sensitive patient data, operational efficiency, and regulatory compliance. Designing such a network for a hospital involves balancing accessibility for authorized personnel with strict security controls to protect confidential information. This paper proposes a comprehensive network design tailored to the hospital’s needs, ensuring secure access to internal resources, safe guest connectivity, and reliable external communication capabilities.

Network Design Overview

The proposed network architecture adopts a layered approach, incorporating core, distribution, and access layers to optimize performance and security. It integrates segmented VLANs, advanced firewall policies, and secure wireless deployments to address distinct user groups and functional requirements.

Internet-Facing Servers and Email Server

The hospital’s Internet-facing servers, including the web and email servers, will reside within a demilitarized zone (DMZ) or perimeter network. This zone is isolated from the internal hospital network to safeguard critical data and prevent untrusted external traffic from compromising internal systems. Firewalls will control inbound and outbound traffic, enforcing strict policies for server access and protecting against cyber threats.

Secure Internal Database Access

The patient records database will be accessible only from the hospital intranet. To restrict access, the internal web-based patient portal will be placed on a secure VLAN, isolated from other hospital network segments. Access controls will include role-based permissions, network ACLs, and secure authentication mechanisms to ensure only authorized personnel—such as medical staff and administrative employees—can access sensitive patient data.

Wireless Network Deployment and Guest Access

Wireless access points (APs) will be strategically deployed throughout the hospital to support mobile devices, medical equipment, and staff laptops. The wireless network will be segmented into multiple SSIDs: one for staff and authorized users, and another for guests. The guest SSID will be isolated from the internal network via VLAN segmentation and will have restricted Internet access only. WPA3 encryption and captive portals will enhance wireless security and ensure user authentication.

Design Justification

The chosen network design emphasizes security, scalability, and ease of management. Segregating network segments via VLANs limits lateral movement in case of security breaches and simplifies policy enforcement. The deployment of firewalls and access controls protects sensitive data while providing necessary connectivity. Wireless segmentation safeguards corporate resources from unauthorized guest access. This design aligns with best practices in hospital network security and ensures compliance with healthcare regulations such as HIPAA.

Network Diagram

The diagram (included as a visual representation) depicts core components including:

  • Internet gateway with perimeter firewall
  • DMZ segment hosting Web and Email servers interconnected through additional firewalls
  • Internal hospital network segmented into VLANs for administrative, clinical, and database services
  • Wireless access points with separate SSIDs for staff and guests
  • Secure connections between segments via managed switches and firewall policies

Conclusion

The proposed network design ensures robust security, efficient resource access, and effective management tailored to the hospital’s operational needs. Implementing layered security measures, network segmentation, and secure wireless deployment will safeguard patient data, support hospital operations, and deliver a seamless user experience for staff and visitors alike.
