This detection rule focuses on monitoring warning events related to user login attempts in the Auth0 authentication service. The primary objective of this rule is to identify any anomalies or issues that arise during the login process, which could be indicative of unauthorized access attempts or misconfigurations in the authentication flow. The rule utilizes Splunk to filter and analyze authentication data, specifically looking for entries classified as 'warning' (denoted by 'w'). The core logic filters for logs that fit this criterion and organizes the data by relevant fields, including session ID, user, source IP, and HTTP user agent. By aggregating this information and tracking timestamped events, security professionals can uncover potential security risks related to user authentication, thereby enabling timely response and remediation of any detected issues or threats.
