I use Oracle only occasionally, but have heard that it is pretty easy to verify if your Oracle encryption is working (e.g. this post Verify if the client is connecting to the Oracle database using native network encryption).
However, for long-term auditing and security reasons, we need to capture TLS levels from connections/sessions to the database. Primarily we need to be able to look at a log or audit table or file and see time, user (or session IP), TLS level/algo, and accepted/rejected.
Is there a view or log file where this is readily available? Or would I have to cobble one together?
