Worked on the zeek/zeek repository to enhance the reliability of login telemetry by refining how successful PostgreSQL logins are reported. Addressed an issue where login success was previously logged upon receiving AuthenticationOk, which could result in false positives if subsequent startup errors occurred. Introduced logic to defer login success reporting until the ReadyForQuery message is received, ensuring only confirmed logins are recorded. This adjustment improved the accuracy of security logging and audit signals, reducing alert noise and strengthening telemetry data quality. Utilized Zeek for backend development, applying skills in network protocol analysis and security logging to improve production event sequencing.
