HIPAA TLS configuration is not optional—it is the backbone of secure healthcare data transmission. Every endpoint that touches ePHI must enforce TLS 1.2 or higher. Lower versions, like TLS 1.0 or 1.1, fail HIPAA’s encryption requirements. Disable them entirely. Use strong cipher suites such as TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 and avoid deprecated ones like RC4, 3DES, or any suite using SHA-1. Forward secrecy is mandatory—enable ECDHE for all secure channels.
For HIPAA compliance, certificates must be issued by a trusted CA, use at least 2048-bit RSA or ECC with P-256 or stronger, and be rotated before expiration. Self-signed certificates in production are not acceptable. Configure strict validation across clients and servers to block invalid or expired certificates.
Enforce HTTPS everywhere with HSTS to prevent protocol downgrade attacks. Strip insecure redirects. Ensure TLS configurations are uniform across APIs, applications, and load balancers so compliance is never broken by a weak link in the path. Audit TLS regularly—changes in dependencies or hosting environments can silently weaken security.
