The class includes a download of a lot real world useful tools and scripts that you can take away and use in your own security assessments of your own Oracle databases.
I made a video of the outline of the class a while ago and this is a good 5 minute discussion of what to expect in the class.
The details from Oracle to enable you to register for this class are here.
I will also be teaching my one day class "Hardening and securing Oracle" on the 1st May also at the same venue with Oracle in London so it will be possible to take both classes as a 3 day event. I will have the registration details for the 3rd day soon from Oracle.
I look forwards to meeting everyone in London in April and being able to teach and discuss securing data in your Oracle databases.
