The 'Auth0 Custom Role Created' rule is designed to monitor the creation of roles within an organization's Auth0 tenant. The rule checks for events where an Auth0 user has the capability to create a new role without legitimate authorization or business justification. Given that role management directly impacts access control and potentially escalates privileges within the organization, this rule carries a high severity level. The analysis is based on the event logs, with a focus on the expected outcomes from user actions related to role creation. If a role is created without adequate permission, it indicates a potential security risk that must be investigated immediately. The rule enables response teams to assess whether a role creation was authorized, according to the organization's policies and regulations, thus mitigating risks associated with unauthorized access and privilege escalation.
