Using SSL in the Oracle Database without surprises

Nowadays databases require to use secure connections to communicate with clients, from application users through listener services, internal features (Apex, OEM), to consuming external services from the database (eg.: sending emails from PL/SQL).
Also security standards keep improving, forcing to use newer algorithms (as SHA2 in TLS 1.2) which requires extra configuration in older database releases.
This session introduces to the topic from a DBA perspective, showing how SSL certificates work, available tools and examples of configuring and troubleshooting their usage from the Oracle database.
We will review traditional and Cloud deployments, exploring also the implementation of TLS 1.2 (SHA2 algorithm) and common errors found from real life usage.
