1. Examine the source and types of the detected error events.
1. Determine whether the errors are originating from a specific user or client.
1. Analyze if the errors are of a particular type to assess whether they indicate an attack or a misconfiguration issue.
1. If the events are confirmed as an attack, take action to block the source to prevent further incidents.
1. Notify affected users about the errors and advise them to take protective measures, such as changing their passwords if suspicious activity is confirmed.
1. Consider conducting a thorough review of security configurations within the realm to identify any vulnerabilities.
