Secure Healthcare Network Using VLAN, OSPF, IPsec VPN and ACL

This proposal supports Sustainable Development Goal 3: Access to Good Health and Well-being by setting up a secure and scalable health infrastructure. It employs several procedures to connect headquarters and branch hospitals, ensuring confidentiality, integrity, and availability of data. These include VLAN segmentation, OSPF routing, and IPsec VPN. VLANs restrict unauthorized access, OSPF gives a low-latency dynamic routing mechanism, and IPsec encrypts the communication to avoid interception. A DHCP server that is installed in-house simplifies IP management. This is a secure and resilient network that forms the foundation for powered health operations safeguarded by patient-oriented data handling.
