I need to analyze and convert data of "security event log" to another format for auditing. Could i reach out to database for its record to search and aggregate? if so could you provide us sufficient information(spec for data and events) about security event log data? Or If not so, I have to analyze the log file "security event log" and its data in it.

I already read this help topic but it help less.
