6.4 Resource AuditEvent - Content

Security Work Group Maturity Level : 3   Trial Use Security Category : Not Classified Compartments : Device , Patient , Practitioner

A record of an event made for purposes of maintaining a security log. Typical uses include detection of intrusion attempts and monitoring for inappropriate usage.

6.4.1 Scope and Usage

The audit event is based on the IHE-ATNA Audit record definitions, originally from RFC 3881 , and now managed by DICOM (see DICOM Part 15 Annex A5 ).

  • ASTM E2147 – Setup the concept of security audit logs for healthcare including accounting of disclosures
  • IETF RFC 3881 – Defined the Information Model (IETF rule forced this to be informative)
  • DICOM Audit Log Message – Made the information model Normative, defined Vocabulary, Transport Binding, and Schema
  • IHE ATNA – Defines the grouping with secure transport and access controls; and defined specific audit log records for specific IHE transactions.
  • NIST SP800-92 – Shows how to do audit log management and reporting – consistent with our model
  • HL7 PASS – Defined an Audit Service with responsibilities and a query interface for reporting use
  • ISO 27789 – Defined the subset of audit events that an EHR would need
  • ISO/HL7 10781 EHR System Functional Model Release 2
  • ISO 21089 Trusted End-to-End Information Flows

This resource is managed collaboratively between HL7, DICOM, and IHE.

The primary purpose of this resource is the maintenance of security audit log information. However, it can also be used for any audit logging needs and simple event-based notification.

6.4.2 Background and Context

All actors - such as applications, processes, and services - involved in an auditable event should record an AuditEvent. This will likely result in multiple AuditEvent entries that show whether privacy and security safeguards, such as access control, are properly functioning across an enterprise's system-of-systems. Thus, it is typical to get an auditable event recorded by both the application in a workflow process and the servers that support them. For this reason, duplicate entries are expected, which is helpful because it may aid in the detection of. For example, fewer than expected actors being recorded in a multi-actor process or attributes related to those records being in conflict, which is an indication of a security problem. There may be non-participating actors, such as trusted intermediary, that also detect a security relevant event and thus would record an AuditEvent, such as a trusted intermediary.

Security relevant events are not limited to communications or RESTful events. They include:

  • software start-up and shutdown;
  • user login and logout;
  • access control decisions;
  • configuration events;
  • software installation;
  • policy rules changes; and
  • manipulation of data that exposes the data to users.

See the Audit Event Sub-Type vocabulary for guidance on some security relevant events.

The content of an AuditEvent is intended for use by security system administrators, security and privacy information managers, and records management personnel. This content is not intended to be accessible or used directly by other healthcare users, such as providers or patients, although reports generated from the raw data would be useful. An example is a patient-centric accounting of disclosures or an access report. Servers that provide support for AuditEvent resources would not generally accept update or delete operations on the resources, as this would compromise the integrity of the audit record. Access to the AuditEvent would typically be limited to security, privacy, or other system administration purposes.

Relationship of AuditEvent and Provenance resources are often (though not exclusively) created by the application responding to the create/read/query/update/delete/execute etc. event. A Provenance resource contains overlapping information, but is a record-keeping assertion that gathers information about the context in which the information in a resource "came to be" in its current state, e.g., whether it was created de novo or obtained from another entity in whole, part, or by transformation. Provenance resources are prepared by the application that initiates the create/update of the resource and may be persisted with the AuditEvent target resource.

It identifies the performed function type : Coding [1..1] « Type of event. null (Strength=Extensible) AuditEventID + » Identifier for the category of event subtype : Coding [0..*] « Sub-type of event. null (Strength=Extensible) AuditEventSub-Type + » Indicator for type of action performed during the event that generated the audit action : code [0..1] « Indicator for type of action performed during the event that generated the event. null (Strength=Required) AuditEventAction ! » The period during which the activity occurred period : Period [0..1] The time when the event was recorded recorded : instant [1..1] Indicates whether the event succeeded or failed outcome : code [0..1] « Indicates whether the event succeeded or failed. null (Strength=Required) AuditEventOutcome ! » A free text description of the outcome of the event outcomeDesc : string [0..1] The purposeOfUse (reason) that was used during the event being recorded purposeOfEvent : CodeableConcept [0..*] « The reason the activity took place. null (Strength=Extensible) v3.PurposeOfUse PurposeOfUse + » Agent Specification of the participation type the user plays when performing the event type : CodeableConcept [0..1] « The Participation type of the agent to the event. null (Strength=Extensible) ParticipationRoleType + » The security role that the user was acting under, that come from local codes defined by the access control security system (e.g. RBAC, ABAC) used in the local context role : CodeableConcept [0..*] « What security role enabled the agent to participate in the event. null (Strength=Example) SecurityRoleType ?? » Reference to who this agent is that was involved in the event who : Reference [0..1] « PractitionerRole | Practitioner | Organization | Device | Patient | RelatedPerson » Alternative agent Identifier. For a human, this should be a user identifier text string from authentication system. This identifier would be one known to a common authentication system (e.g. single sign-on), if available altId : string [0..1] Human-meaningful name for the agent name : string [0..1] Indicator that the user is or is not the requestor, or initiator, for the event being audited requestor : boolean [1..1] Where the event occurred location : Reference [0..1] « Location » The policy or plan that authorized the activity being recorded. Typically, a single activity may have multiple applicable policies, such as patient consent, guarantor funding, etc. The policy would also indicate the security token used policy : uri [0..*] Type of media involved.

6.4.3.3 6.4.4.3 Using Coded Values

The AuditEvent resource and the ATNA Audit record are used in many contexts throughout healthcare. The coded values defined in the "extensible" bindings above are those widely used and/or defined by DICOM, IHE or ISO, who defined these codes to meet very specific use cases. These codes should be used when they are suitable. When needed, other codes can be defined.

Note: When using codes from a vocabulary, the display element for the code can be left off to keep the AuditEvent size small and minimize impact of a large audit log of similar entries.

The set of codes defined for this resource is expected to grow over time, and additional codes may be proposed / requested using the "Propose a change" link above below.

6.4.3.4 6.4.4.4 Event codes for Common Scenarios

This table summarizes common event scenarios, and the codes that should be used for each case.

Scenario type subtype action Other
User Login ( example ) 110114 User Authentication 110122 User Authentication E Execute One agent which contains the details of the logged-in user.
User Logout ( example ) 110114 User Authentication 110123 User Logout E Execute One agent which contains the details of the logged-out user.
REST operation logged on server ( example ) rest RESTful Operation [code] defined for operation * (see below) Agent for logged in user, if available.
Search operation logged on server ( example ) rest RESTful Operation [code] defined for operation E Execute Agent for logged in user, if available, and one object with a query element.

Audit Event Actions for RESTful operations:

Operation Action
create C
read, vread, history-instance, history-type, history-system R
update U
delete D
transaction, operation, conformance, validate, search, search-type, search-system E

6.4.3.5 6.4.4.5 Encoding a FHIR operation outcome

FHIR interactions can result in a rich description of the outcome using the OperationOutcome . The OperationOutcome Resource is a collection of error, warning or information messages that result from a system action. This describes in detail the outcome of some operation, such as when a RESTful operation fails.

When recording into an AuditEvent that some FHIR interaction has happened, the AuditEvent should include the OperationOutcome from that FHIR interaction. This is done by placing the OperationOutcome into an AuditEvent.entity. Likely as a contained resource, given that OperationOutcome resources often are not persisted.

entity.who is the OperationOutcome -- Likely contained

entity.type is code OperationOutcome

entity.description explains why this OperationOutcome was included.

See transaction failure example : When a client attempts to post (create) an Observation Resource, using a server Patient endpoint; this would result in an error with an OperationOutcome.

6.4.3.6 6.4.4.6 PurposeOfEvent and PurposeOfUse

The AuditEvent provides the element purposeOfEvent to convey the purpose of the event and purposeOfUse to convey the reason that a particular actor (machine, person, software) was involved in the event.

purposeOfEvent is an element at the level of AuditEvent and can convey the purpose of the activity that resulted in the event. This will occur when the system that is reporting the event is aware of the purpose of the event. A specific example would be a radiology reporting system where a radiologist has created and is sending a finished report. This system likely knows the purpose, e.g., "treatment". It is multi-valued because the one event may be related to multiple purposes.

It is also commonplace that the reporting system does not have information about the purpose of the event. In these cases, the event report would not have a purposeOfEvent.

It is also likely that the same event will be reported from different perspectives, e.g., by both the sender and recipient of a communication. These two different perspectives can have different knowledge regarding the purposeOfEvent .

purposeOfUse is an element at the level of agent within AuditEvent. This describes the reason that this person, machine, or software is participating in the activity that resulted in the event. For example, an individual person participating in the event may assert a purpose of use from their perspective. It is also possible that they are participating for multiple reasons and report multiple purposeOfUse.

The reporting system might not have knowledge regarding why a particular machine or person was involved and would omit this element in those cases.

When the same event is reported from multiple perspectives, the reports can have different knowledge regarding the purpose.
