Cisco-based secure network for HIPAA-compliant patient monitoring.

🏥 Protecting Patients Through Network Security

How I isolated medical devices using Cisco networking fundamentals

📌 The Challenge

Imagine a busy hospital where patient heart monitors sit on the same network as visitor smartphones. That's not just risky - it's dangerous!

My mission:
Create a safe digital environment where sensitive medical equipment is protected from general hospital traffic while meeting strict healthcare privacy laws (HIPAA).

My solution:
I built a 3-layer security shield:

1. Digital quarantine zones (VLANs) for medical devices
2. Smart traffic filters (ACLs) blocking non-essential protocols
3. Port lockdowns preventing unauthorized devices from connecting

The Brains Behind the Security

Here's a peek at the digital "rules" I created to protect patient monitors:

! Creating a safe traffic zone for medical devices
ip access-list extended MEDICAL-ONLY  
 permit tcp 192.168.10.0 0.0.0.255 any eq 443  // Allow secure medical data
 deny   tcp any any eq 3389                    // Block risky remote access
