Description

What does HIPAA require for MySQL databases?

HIPAA demands confidentiality, integrity, and availability of PHI. In MySQL this means TLS encryption in transit, AES encryption at rest, strict role-based access control, continuous auditing, and robust backup policies.

How do I encrypt data at rest?

Enable innodb_encrypt_tables and innodb_encrypt_log to encrypt InnoDB tablespaces and redo logs. Use ALTER TABLE … ENCRYPTION=‘Y’ for existing tables holding PHI such as Customers or Orders.

Example: Encrypt the Customers table

ALTER TABLE Customers ENCRYPTION='Y';

How do I secure data in transit?

Create X.509 certificates, copy them to the MySQL server, and set require_secure_transport = ON. Clients then connect with --ssl-ca, --ssl-cert, and --ssl-key flags.

How do I implement least-privilege access?

Grant users only the statements they need. Separate read-only analysts from write-enabled app users. Revoke FILE, PROCESS, and SUPER unless absolutely necessary.

Example: Read-only analyst role

CREATE USER 'analyst'@'%' IDENTIFIED BY 'Strong!Pass1'; GRANT SELECT ON ecommerce.* TO 'analyst'@'%';

How do I enable auditing?

Install the MySQL Enterprise Audit plugin or the open-source audit_log plugin. Configure a JSON log policy to record logins, DDL, and DML on PHI tables.

How do I prove compliance?

Store audit logs off-box, test disaster recovery restores quarterly, and keep documented policies. Automate daily checks of SHOW VARIABLES to verify encryption and logging remain active.

Why How to Achieve HIPAA Compliance in MySQL is important

How to Achieve HIPAA Compliance in MySQL Example Usage


-- Query PHI while respecting least-privilege
SELECT c.name,
       o.order_date,
       o.total_amount
FROM   Customers  c
JOIN   Orders     o ON o.customer_id = c.id
WHERE  o.order_date >= CURDATE() - INTERVAL 30 DAY;

How to Achieve HIPAA Compliance in MySQL Syntax


-- Enable at-rest encryption
SET GLOBAL innodb_encrypt_tables = ON;
SET GLOBAL innodb_encrypt_log    = ON;

-- Encrypt existing tables containing PHI
aLTER TABLE Customers  ENCRYPTION='Y';
aLTER TABLE Orders     ENCRYPTION='Y';

-- Force TLS connections
[mysqld]
require_secure_transport = ON
ssl_cert = /etc/mysql/server-cert.pem
ssl_key  = /etc/mysql/server-key.pem
ssl_ca   = /etc/mysql/ca.pem

-- Create and restrict users
CREATE USER 'app'@'%' IDENTIFIED BY 'S8cure!';
GRANT SELECT,INSERT,UPDATE,DELETE ON ecommerce.* TO 'app'@'%';

CREATE USER 'analyst'@'%' IDENTIFIED BY 'View0nly!';
GRANT SELECT ON ecommerce.* TO 'analyst'@'%';

-- Enable auditing (Community)
INSTALL PLUGIN audit_log SONAME 'audit_log.so';
SET GLOBAL audit_log_policy = 'LOGINS,QUERIES';

Common Mistakes

Relying on disk-level encryption only. This protects lost drives but not a live server where a root user can read data. Fix by enabling InnoDB tablespace encryption and column-level encryption for sensitive fields.
Granting ALL PRIVILEGES to application accounts. This violates the least-privilege principle and may expose PHI. Fix by granting only the minimal CRUD statements on required schemas.

Frequently Asked Questions (FAQs)

Do I need MySQL Enterprise to be HIPAA-compliant?

No, Community Edition plus the open-source audit_log plugin, TLS, and InnoDB encryption can satisfy HIPAA’s technical safeguards, though Enterprise simplifies auditing.
