HIPAA’s technical safeguards define how electronic protected health information (ePHI) is stored, accessed, and transmitted. For databases, this means implementing strict access controls, encryption, audit logs, and authentication processes that stand up to regulatory scrutiny.
Access control is the first line. Only authorized users should touch the data. This requires unique user IDs, role-based permissions, and automatic logoff for inactive sessions. Each query, each connection, must be traceable to a verified identity.
Transmission security comes next. All data in motion between applications and databases must be encrypted. TLS 1.2 or better is standard. No plaintext packets. No open ports leaking information into the void.
Integrity controls ensure data remains accurate and complete. This involves hashing, digital signatures, and mechanisms to detect unauthorized changes. The database must reject altered or corrupted records. Every transaction must match the checksum.
