The 'Auth0 Integration Installed' rule is designed to monitor the installation of integrations from the Auth0 action library within the organization. When an integration is installed, a log entry is created indicating various details, including the user who performed the action, the time of the event, and the specifics of the integration along with its status code. This rule is particularly important as unauthorized installations could indicate security risks, such as an insider threat or a misconfiguration. The associated runbook suggests assessing the installation for a valid business reason and encourages vigilance regarding the re-enabling of this setting, ensuring that it aligns with security best practices. Additionally, the rule is set to deduplicate alerts over a 60-minute period, consolidating notifications for multiple installs that occur within a short timeframe. The severity level of this rule is classified as 'Info', indicating that while important, it may not represent immediate threats, but should be tracked for unusual activities.
