Information System Activity Reviewed
Plain English Translation
Organizations must establish procedures to regularly review audit logs, access reports, and security incident tracking data to detect unauthorized access to or abnormal use of ePHI. These reviews must be documented and performed on a consistent schedule to ensure threats are identified and acted upon promptly.
Technical Implementation
Use the tabs below to select your organization size.
Required Actions (startup)
- Enable basic audit logging on all applications and servers handling ePHI and schedule a documented weekly review of critical access events.
Required Actions (scaleup)
- Implement a centralized logging server or basic SIEM to aggregate logs, establish automated alerts for failed logins, and formalize an incident escalation workflow.
Required Actions (enterprise)
- Deploy an advanced SIEM with user and entity behavior analytics (UEBA) to continuously monitor and alert on anomalous access patterns across the entire enterprise.
The HIPAA information system activity review is a required administrative safeguard where organizations establish procedures to regularly review records of information system activity to detect security violations.
HIPAA requires organizations to implement procedures to regularly review audit logs, access reports, and security incident tracking reports to monitor access to electronic protected health information.
While HIPAA does not specify an exact timeframe, logs should be reviewed regularly based on the organization's risk assessment, typically daily or weekly for critical systems storing ePHI.
Organizations must review system audit logs, access reports, and security incident tracking reports that monitor successful and failed attempts to access ePHI.
Yes, the Security Rule explicitly requires organizations to include the review of access reports within their information system activity review procedures.
Audit logs provide a chronological record of system activity, allowing security teams to identify suspicious patterns, unauthorized login attempts, and unauthorized viewing or exfiltration of ePHI.
HIPAA 164.308(a)(1)(ii)(D) is the specific implementation specification under the Security Management Process that mandates the review of information system activity, including audit logs and access reports.
A log review procedure should detail which logs are collected, the frequency of reviews, the specific anomalies being monitored, the personnel responsible, and the escalation process for suspected incidents.
The designated HIPAA Security Officer or their delegated security personnel and system administrators are typically responsible for conducting and documenting routine audit log reviews.
HIPAA requires that documentation of policies, procedures, and actions, which includes the procedures and records of log reviews, be retained for six years from the date of its creation or when it was last in effect.
Log review is not only about detecting suspicious activity; organizations also need evidence showing reviews happened, findings were evaluated, and follow-up actions were tracked. Tools like WatchDog Security's Compliance Center can help organize audit log review records, map evidence to HIPAA requirements, and identify gaps before an audit.
Audit logs often reveal access events after they occur, but security teams also need visibility into risky configurations that may increase the chance of unauthorized ePHI access. Tools like WatchDog Security's Posture Management can help detect misconfigurations, surface remediation guidance, and support a more complete review of abnormal system behavior.
