Test, validate and match regular expressions
This regular expression matches audit log entries from the Microsoft Windows Eventlog, specifically extracting the audit outcome (Success or Failure), log date, event ID, category, event message, and an associated count of events. It expects a comma-separated format that begins with the word 'Audit' and parses the data into named capture groups for easy data extraction. It is useful for security information and event management (SIEM) systems or log parsing scripts processing Windows security audits.
