What is the HIPAA Security Rule?
The HIPAA Security Rule (45 CFR Part 164, Subpart C) establishes national standards for protecting electronic Protected Health Information (ePHI). It applies to all covered entities and business associates who create, receive, maintain, or transmit ePHI.
Technical Safeguards (§ 164.312)
The Security Rule's technical requirements are where most organizations need the most guidance:
#### § 164.312(a)(1) — Access Control
Requirement: Implement technical policies and procedures for electronic information systems that maintain ePHI to allow access only to those persons or software programs that have been granted access rights.
Practical Implementation:
Unique User Identification (Required): Assign a unique name and/or number for identifying and tracking user identity
Emergency Access Procedure (Required): Establish procedures for obtaining ePHI during an emergency
Automatic Logoff (Addressable): Implement electronic procedures that terminate an electronic session after a predetermined time of inactivity
Encryption and Decryption (Addressable): Implement a mechanism to encrypt and decrypt ePHI#### § 164.312(c)(1) — Integrity Controls
Requirement: Implement policies and procedures to protect ePHI from improper alteration or destruction.
Practical Implementation:
Hash verification for evidence records
Digital signatures for compliance documents
Immutability guarantees through cryptographic ledgers
Version control for configuration changes#### § 164.312(b) — Audit Controls
Requirement: Implement hardware, software, and/or procedural mechanisms that record and examine activity in information systems that contain or use ePHI.
Practical Implementation:
Comprehensive audit logging of all ePHI access
Immutable audit trail storage
Regular audit log review procedures
Automated anomaly detection#### § 164.312(e)(1) — Transmission Security
Requirement: Implement technical security measures to guard against unauthorized access to ePHI that is being transmitted over an electronic communications network.
Practical Implementation:
TLS 1.3 for all ePHI transmissions
End-to-end encryption for data in transit
VPN requirements for remote access
Certificate pinning for API communicationsAWS HIPAA Compliance Checklist
For organizations running on AWS, here are the 20 most critical checks:
S3 Bucket Encryption: Enable SSE-S3 or SSE-KMS for all buckets containing PHI
S3 Versioning: Enable versioning on all PHI-containing buckets
S3 Bucket Policies: Restrict access to authorized roles only
S3 Public Access Block: Enable Block Public Access on all accounts
IAM MFA: Require MFA for all IAM users with console access
IAM Least Privilege: Use role-based policies, not wildcard permissions
IAM Break-Glass: Implement emergency access procedures
CloudTrail Logging: Enable CloudTrail in all regions
CloudTrail Log Validation: Enable log file integrity validation
CloudWatch Monitoring: Set up alarms for security events
VPC Configuration: Use private subnets for PHI workloads
RDS Encryption: Enable encryption at rest for all RDS instances
RDS Backup: Configure automated backups with appropriate retention
ELB Logging: Enable access logs for all Application Load Balancers
GuardDuty: Enable GuardDuty for threat detection
Config Rules: Deploy HIPAA-relevant AWS Config Rules
KMS Key Rotation: Enable automatic key rotation for KMS keys
EC2 Public IP: Alert on any EC2 instances with public IP addresses
SNS Alerts: Configure SNS for compliance notifications
CloudWatch Dashboards: Create dashboards for compliance monitoringMonitoring and Evidence Collection
Implementing these controls is only half the battle. Provingyou've implemented them is equally important. This is where automated evidence collection tools like Votexia shine — continuously verifying that each control remains in compliance and generating cryptographic proof for auditors.
The Security Rule isn't just about having the right configuration on day one — it's about maintaining it continuously, detecting drift, and having the evidence to prove compliance at any moment.
