Protected Health Information (PHI) - Complete Guide for AWS Developer Associate
What is Protected Health Information (PHI)?
Protected Health Information (PHI) refers to any individually identifiable health information that is created, received, maintained, or transmitted by a covered entity or business associate. This includes demographic data, medical histories, test results, insurance information, and any other information that can be used to identify a patient and relates to their past, present, or future physical or mental health condition.
Why is PHI Important?
PHI is governed by the Health Insurance Portability and Accountability Act (HIPAA) in the United States. Understanding PHI is crucial because:
• Legal Compliance: Organizations handling PHI must comply with strict regulations or face significant penalties • Patient Privacy: Protecting sensitive health data maintains trust between healthcare providers and patients • Security Requirements: PHI requires specific technical safeguards, access controls, and encryption standards • AWS Responsibility: When building healthcare applications on AWS, developers must implement appropriate controls
How PHI Works in AWS Context
When handling PHI on AWS, you must consider:
• Business Associate Agreement (BAA): AWS offers a BAA that covers specific HIPAA-eligible services • Encryption: PHI must be encrypted both at rest and in transit using services like AWS KMS, S3 encryption, and TLS • Access Controls: Implement strict IAM policies and use AWS CloudTrail for audit logging • HIPAA-Eligible Services: Only certain AWS services are covered under the BAA, including EC2, S3, RDS, Lambda, and DynamoDB • Data Residency: Ensure PHI remains in compliant regions and follows data sovereignty requirements
Key AWS Services for PHI Protection
• AWS KMS - Key management for encryption • Amazon S3 - Secure storage with server-side encryption • Amazon RDS - Encrypted database storage • AWS CloudTrail - Audit logging for compliance • Amazon VPC - Network isolation and security • AWS Config - Compliance monitoring and resource configuration tracking
Exam Tips: Answering Questions on Protected Health Information (PHI)
1. Always Choose Encryption: When PHI is involved, select answers that include encryption at rest AND in transit
2. Look for BAA References: Remember that a Business Associate Agreement must be in place before storing PHI on AWS
3. HIPAA-Eligible Services: Know which services are covered under AWS BAA - not all services qualify
4. Audit and Logging: Questions about PHI compliance often have correct answers involving CloudTrail, CloudWatch, or AWS Config
5. Access Control Focus: Answers involving least privilege access, MFA, and strict IAM policies are typically correct for PHI scenarios
6. Shared Responsibility Model: AWS secures the infrastructure, but YOU are responsible for configuring services correctly for HIPAA compliance
7. Data Classification: PHI is considered highly sensitive data - treat it with the highest security controls available
8. Watch for Distractors: Answers suggesting storing PHI in publicly accessible locations or using unencrypted services are incorrect
9. Regional Considerations: Be aware that PHI may have specific data residency requirements
10. Remember the 18 Identifiers: PHI includes names, addresses, dates, phone numbers, email addresses, SSN, medical record numbers, and other identifiers that can link data to an individual
