Configuring auditing to track events

Keycloak includes a suite of auditing capabilities. You can record every login and administrator action and review those actions in the Admin Console. Keycloak also includes a Listener SPI that listens for events and can trigger actions. Examples of built-in listeners include log files and sending emails if an event occurs.

Auditing user events

You can record and view every event that affects users. Keycloak triggers login events for actions such as successful user login, a user entering an incorrect password, or a user account updating. By default, Keycloak does not store or display events in the Admin Console. Only the error events are logged to the Admin Console and the server’s log file.

Procedure

Use this procedure to start auditing user events.

  1. Click Realm settings in the menu.

  2. Click the Events tab.

  3. Click the User events settings tab.

  4. Toggle Save events to ON.

Each event has a corresponding error event.

Event listener

Event listeners listen for events and perform actions based on that event. Keycloak includes two built-in listeners, the Logging Event Listener and Email Event Listener.

The logging event listener

When the Logging Event Listener is enabled, this listener writes to a log file when an error event occurs.

An example log message from a Logging Event Listener:

11:36:09,965 WARN  [org.keycloak.events] (default task-51) type=LOGIN_ERROR, realmId=master,
                    clientId=myapp,
                    userId=19aeb848-96fc-44f6-b0a3-59a17570d374, ipAddress=127.0.0.1,
                    error=invalid_user_credentials, auth_method=openid-connect, auth_type=code,
                    redirect_uri=http://localhost:8180/myapp,
                    code_id=b669da14-cdbb-41d0-b055-0810a0334607, username=admin

You can use the Logging Event Listener to protect against hacker bot attacks:

  1. Parse the log file for the LOGIN_ERROR event.

  2. Extract the IP Address of the failed login event.

  3. Send the IP address to an intrusion prevention software framework tool.

The Logging Event Listener logs events to the org.keycloak.events log category. Keycloak does not include debug log events in server logs, by default.

To include debug log events in server logs:

  1. Change the log level for the org.keycloak.events category

  2. Change the log level used by the Logging Event listener.

To change the log level used by the Logging Event listener, add the following:

bin/kc.[sh|bat] start --spi-events-listener-jboss-logging-success-level=info --spi-events-listener-jboss-logging-error-level=error

The valid values for log levels are debug, info, warn, error, and fatal.

The Email Event Listener

The Email Event Listener sends an email to the user’s account when an event occurs and supports the following events:

  • Login Error.

  • Update Password.

  • Update Time-based One-time Password (TOTP).

  • Remove Time-based One-time Password (TOTP).

Procedure

To enable the Email Listener:

  1. Click Realm settings in the menu.

  2. Click the Events tab.

  3. Click the Event listeners field.

  4. Select email.

You can exclude events by using the --spi-events-listener-email-exclude-events argument. For example:

kc.[sh|bat] --spi-events-listener-email-exclude-events=UPDATE_TOTP,REMOVE_TOTP

You can set a maximum length of the Event detail in the database by using the --spi-events-listener-email-exclude-events argument. This setting is useful if a field (for example, redirect_uri) is long. For example:

kc.[sh|bat] --spi-events-listener-email-max-detail-length=1000

Auditing admin events

You can record all actions that are performed by an administrator in the Admin Console. The Admin Console performs administrative actions by invoking the Keycloak REST interface and Keycloak audits these REST invocations. You can view the resulting events in the Admin Console.

Procedure

Use this procedure to start auditing admin actions.

  1. Click Realm settings in the menu.

  2. Click the Events tab.

  3. Click the Admin events settings tab.

  4. Toggle Save events to ON.

    Keycloak displays the Include representation switch.

  5. Toggle Include representation to ON.

    The Include Representation switch includes JSON documents sent through the admin REST API so you can view the administrators actions.
