Description

Security Lists control traffic flowing into and out of Subnets within a VCN (Virtual Cloud Network). Monitoring and alerting on changes to Security Lists by using the OCI Events Service will help in identifying changes to these security controls. OCI Events Service enables you to create automation based on the state changes of resources throughout your tenancy. With Event Rules, developers can respond to changes in real-time by triggering code with Functions, writing to Streaming, or sending alerts using Notifications. It was detected that there is no Notification configured for Security List changes under root compartment (tenancy) {OciIdentityCompartment.Name}. Event Rules are compartment scoped and will detect events in child compartments. Therefore, it is advised to create the Event Rule at the root compartment level.

  Recommended Mitigation

  It is recommended to setup an Event Rule and Notification at the root compartment (tenancy) level that gets triggered when Security Lists are created, updated or deleted.
