Java forensics and Apps Security (twice)
I also saw via Joxeans twitter that he has posted his "Oracle hackproofing Oracle financials R12" presentation from rooted conference. This is a nice presentation covering some old 11i issues and some new R12 issues.
I also bought recently the new book by Jeff Hare - "Oracle E-Business Suite Controls: Application Security Best Practices (Paperback)" which is very good and is also supposed to be the first in a series of books on E-Business Suite security and controls. I liked the book very much and read it on a couple of plane rides recently. I have also just ordered the newest version of the little ISACA Oracle database security book, some words on that when it arrives from the states.
