Auditing Service

ESS Auditing Service audits various activities from the ESS services, including itself.

For more information on auditing, see Auditing

By default, auditing is enabled and logs the audit events to sysout.

ESS uses asynchronous messaging for auditing.

To ensure that audit messages are delivered, the Audit Service may send the message more than once.

For instance, multiple instances of the Audit Service may exist when applying configuration changes or when performing a rolling upgrade. During this time, duplicate messages (i.e., messages with the same unique id value) can occur if the old Audit instance processes a message but shuts down before acknowledging the message on Kafka, and then, the new Audit instance processes the unacknowledged message.

Note

The Auditing Service continues to run when auditing is disabled; instead, disabling auditing stops the ESS services from publishing audit events.

Audit Events

A complete list of Audit Events can be found at Audit Events.

For auditing event examples, see Appendix: Audit Events Examples.

Integration with External Logging Systems

The ESS Auditing Service can log to:

• sysout (default)

• Syslog

• Microsoft Sentinel

When logging audit messages to sysout (the default), Auditing service uses the shared ESS logging components, which use JSON as the default formatting for log messages. As such, audit messages logged to sysout are contained in the auditEvent field of the log message. The audit event message itself (i.e., the auditEvent value) is serialized as a JSON-LD documents.

Integration with Syslog

The ESS Auditing Service can integrate with Syslog. When integrating with Syslog, ESS audit events are converted to Syslog message format:

<priority>version timestamp hostname service processId messageId message

Where:

• hostname , service , processId and messageId values are taken extracted from the audit event agent field.

• message is the full ESS audit event message in JSON.

For example (the event message has been abbreviated):

<110>1 2022-01-12T20:17:08.387Z ess-pod-storage-84648cfc95-qs865 inrupt-storage-postgres-s3 85 urn:uuid:579668c1-4e14-4fad-aea3-0000000005 { "@context": [ "https://www.w3.org/ns/activitystreams", "https://schema.inrupt.com/audit/v1.jsonld" ], "id": "urn:uuid:579668c1-4e14-4fad-aea3-0000000005", "type": ["Activity", "Create"], "name": "resource-created", "summary": "Resource has been created", ... }

By default, the Auditing service logs to sysout . To have the service output to Syslog instead, see Manage Auditing.

See also Syslog configuration options.

For more information on Syslog, see RFC 5424.

Integration with Sentinel

The ESS Auditing Service can integrate with Microsoft Sentinel.

When integrating with Microsoft Sentinel, the ESS audit events are converted into a Sentinel-specific format and POST ’ed to the Sentinel service.

By default, the Auditing Service logs to sysout . To have the service output to Sentinel instead, see Manage Auditing.

See also Sentinel configuration options.

Configuration

As part of the installation process , Inrupt provides base Kustomize overlays and associated files that require deployment-specific configuration inputs.

The following configuration options are available for the service and may be set as part of updating the inputs for your deployment. The Inrupt-provided base Kustomize overlays may be using updated configuration values that differ from the default values.

General Configuration

QUARKUS_HTTP_PORT

Default : 8080

The HTTP port the audit service runs on.

QUARKUS_LOG_LEVEL

Default : INFO

Logging level.

Kafka

Tip See also ESS’ Kafka Configuration.

INRUPT_KAFKA_AUDITV1EVENTSENCRYPTED_CIPHER_PASSWORD

Application-Defined Metadata Propagation

INRUPT_AUDIT_PRODUCER_REQUEST_METADATA_ALLOW

A comma-separated list of application-defined properties that can be included in the associated audit events (unless specified in the corresponding INRUPT_AUDIT_PRODUCER_REQUEST_METADATA_DENY).

This configuration is case-sensitive to the propagated properties in the baggage.

Tip To include a propagated property that was added via the INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_ALLOW configuration, ensure that the cases of these properties match.

See:

• Manage Application-Defined Metadata Propagation to configure.

• Application-Defined Metadata for more information.

INRUPT_AUDIT_PRODUCER_REQUEST_METADATA_DENY

A comma-separated list of application-defined properties to exclude from the associated audit messages. This setting takes precedence over INRUPT_AUDIT_PRODUCER_REQUEST_METADATA_ALLOW.

This configuration is case-sensitive to the propagated properties in the baggage.

Tip To exclude a propagated property that was added via the INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_ALLOW configuration, ensure that the cases of these properties match.

See:

• Manage Application-Defined Metadata Propagation to configure.

• Application-Defined Metadata for more information.

INRUPT_LOGGING_REQUEST_METADATA_ALLOW

A comma-separated list of application-defined properties that can be included in the associated log messages (unless specified in the corresponding INRUPT_LOGGING_REQUEST_METADATA_DENY).

• Application-Defined Metadata for more information.

INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_ALLOW

A comma-separated list of non-baggage request headers to add to the baggage (unless specified in the corresponding INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_DENY); i.e., include these non-baggage request headers as application-defined properties.

The configuration is case-insensitive; i.e., the listed headers do not need to match the case of the client request headers. For example, a list that includes x-correlation-id can match x-correlation-id header, X-CoRrElAtIoN-Id header, etc.

See:

• Manage Application-Defined Metadata Propagation to configure.

• Application-Defined Metadata for more information.

INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_DENY
