Data integrity maintained

The HIPAA data integrity requirement mandates that organizations implement policies and procedures to protect electronic protected health information (ePHI) from improper alteration or destruction.

HIPAA § 164.312(c)(1) requires covered entities and business associates to establish security measures that prevent unauthorized modification or deletion of ePHI.

You protect ePHI by implementing technical safeguards like file integrity monitoring, strict access controls, cryptographic hashing, and maintaining secure, immutable backups.

Examples include role-based access restrictions, digital signatures, checksum validation, version control systems, and automated file integrity monitoring software.

Under the HIPAA Security Rule, the overarching data integrity standard is a required implementation specification that must be fully addressed to ensure compliance.

A mechanism to authenticate ePHI is a technical process, such as hashing or digital signatures, used to corroborate that health data has not been altered or destroyed in an unauthorized manner.

Audit logs record all system activity, allowing security teams to track exactly who accessed or modified ePHI, which is critical for detecting and investigating unauthorized alterations.

WatchDog Security's Compliance Center can help organize log review evidence and link it to the relevant HIPAA control for audit readiness.

Auditors expect to see formal data protection policies, evidence of access reviews, configuration settings for integrity monitoring tools, and logs showing real-time alerting for data changes. WatchDog Security's Compliance Center can help maintain this evidence in one place so teams can show whether each required artifact is current, assigned, and reviewed.

Data integrity focuses on preventing unauthorized alteration or destruction of ePHI at rest, while transmission security safeguards ePHI from interception or modification while it is actively being transmitted over a network.

HIPAA data integrity controls often produce evidence across many systems, including access reviews, audit logs, backup records, and change monitoring alerts. WatchDog Security's Compliance Center can help centralize that evidence, map it to HIPAA § 164.312(c)(1), and identify gaps where supporting documentation is missing or stale.

Data integrity depends on secure configurations across systems that store or process ePHI, because weak permissions, disabled logging, or exposed storage can increase the risk of unauthorized changes. WatchDog Security's Posture Management can help detect misconfigurations and provide remediation guidance for systems that support ePHI protection.
