Description

Ensure an Events Service rule in the root compartment watches for sign-ins by local OCI users and has an action that sends a notification to a monitored topic. The rule should match all of the related event types, so the security team is alerted as soon as these changes happen.

Rationale

Most users should sign in through a federated identity provider, so sign-ins by local users, especially break-glass administrators, should be rare. Alerting on local user authentication helps detect stolen credentials, unusual sign-in times, or use of emergency accounts that should normally stay untouched.

Impact

  • The security team is alerted when a local user signs in to the Console

  • Speeds up detection of unauthorized or accidental changes

  • Alert volume depends on how often these changes happen

Default Value

By default, no event rules or notification topics are configured.

Pre-Requisites

  • Permission to manage cloudevents-rules and ons-topics in the root compartment

  • A notification topic with at least one confirmed subscription (for example, the security team's email address)

Test Plan

  1. Sign in to the OCI Console at https://cloud.oracle.com.

  2. Open the navigation menu, select Observability & Management, and under Events Service select Rules. In the Compartment filter, select the root compartment (tenancy).

  3. Look for an enabled rule whose conditions match the Identity SignOn service and these event types: Interactive Login.

  4. Open the rule and verify that its Actions include a Notifications action pointing to a topic with an active subscription.

  5. If no such rule exists, or it has no notification action, follow the implementation steps.

Implementation Steps

  1. Sign in to the OCI Console at https://cloud.oracle.com.

  2. If you do not have a topic, open Developer Services > Application Integration > Notifications, select Create topic, then create a subscription (for example, Email) and confirm it.

  3. Open the navigation menu, select Observability & Management, and under Events Service select Rules. In the Compartment filter, select the root compartment (tenancy).

  4. Select Create rule and enter a name, for example notify-on-local-user-login.

  5. Under Rule conditions, choose Event type, select Service name Identity SignOn, and select the event types: Interactive Login.

  6. Under Actions, choose Action type Notifications, and select the compartment and topic.

  7. Select Create rule.

Backout Plan

  1. Sign in to the OCI Console at https://cloud.oracle.com.

  2. Open the navigation menu, select Observability & Management, and under Events Service select Rules. In the Compartment filter, select the root compartment (tenancy).

  3. Select the rule and select Disable, or delete the rule.
