I wrote a presentation on designing and building practical audit trails back in 2012 and presented it once and then never again. By chance I did not post the pdf's of these slides at that time. I did though some time after create a full one day training course that I have taught many times now on the same subject. I recently was asked by the UKOUG to present the same talk again at the UKOUG Database SIG in London at Oracles office on September 15th 2015. So I went down to London and did just that. I updated the slides and made many changes to the whole paper and some major and some minor changes to most slides.
This paper went down reasonably well and we had some good questions and good chats there. The slides have been posted to my
Oracle Security White Papers page so please head over there and download the pdf's if you are interested.
