Transmission Security
Description
Implement technical security measures to guard against unauthorized access to ePHI transmitted over electronic networks.
⚠️ Risk Impact
Unencrypted ePHI in transit can be intercepted on the network.
🔧 Remediation
Enforce TLS 1.2+ on all connections. EchelonGraph checks SSL/TLS configurations.
💀 Real-World Attack Scenario
A healthcare analytics platform transmitted ePHI between microservices over unencrypted HTTP within a VPC. An attacker who compromised a single VM used packet capture to intercept patient demographics, diagnoses, and prescription data flowing between services. The breach affected 340,000 patients.
💰 Cost of Non-Compliance
HIPAA §164.312(e)(1) citations carry penalties of $100K-$1.5M per violation category. ePHI interception breaches require full patient notification. Average notification cost: $150/patient.
📋 Audit Questions
- 1.Are ALL connections transmitting ePHI encrypted with TLS 1.2+?
- 2.Is internal (east-west) traffic also encrypted?
- 3.How are TLS certificates managed and renewed?
- 4.Are VPN/IPsec tunnels used for cross-site ePHI transmission?
🎯 MITRE ATT&CK Mapping
⚡ Common Pitfalls
- ⛔Encrypting external traffic but not internal microservice communication
- ⛔Using TLS 1.0 or 1.1 for legacy system compatibility
- ⛔HL7/FHIR interfaces operating over unencrypted channels
📈 Business Value
End-to-end ePHI encryption prevents data interception even in compromised networks. It provides HIPAA compliance and protects against the growing threat of lateral movement attacks in healthcare.
