Completed this learning path in my Oracle Learning Subscription:
"Discover and Train in CyberSecurity"
https://learn.oracle.com/ols/learning-path/discover-and-train-in-cybersecurity/35644/100307
Not a bad little training course. Only took a couple of hours to finish it. Got to say it makes me intereted in learning more about Oracle's new gen 2 infrastructure. Right now it is free so I highly recommend it.
