The rule titled 'My First Rule' is designed as a guided onboarding tool for users of Elastic Security, aimed at familiarizing analysts with the alerting system. It operates by monitoring event data broadly without signaling actual threat activity, thereby serving primarily educational purposes. It utilizes various logs from sources like auditbeat, filebeat, and winlogbeat to create alerts based on event data indexed. As the rule does not target specific threats, there are concerns about false positives, highlighting the need for analysts to discern between normal operational events and indicators of potential security incidents. The investigation steps outlined emphasize the importance of reviewing event contexts, timestamps, and associated users to filter out noise. Alerts generated by this rule occur every 24 hours for each host, and it’s suggested that users disable the rule if they are already comfortable with the alerting mechanisms of Elastic Security. This rule underscores the role of familiarization in security architecture, encouraging proactive engagement with event data management.
