Oracle has some security specific information on the OTN page -
http://www.oracle.com/technology/dep...ity/index.html
One you may find particularly useful is the 9iR2 security checklist -
http://otn.oracle.com/deploy/securit..._checklist.pdf
(although I couldn't find this linked anywhere on that page...odd)

Pete Finnigan, though, is propably the best reference for Oracle
security information. He has a comprehensive list of Oracle security
references here: http://www.petefinnigan.com/orasec.htm

There have been several other good Oracle whitepapers including those
written by AppSec, Inc
(http://www.appsecinc.com/techdocs/wh.../research.html),
Integrigy (http://www.integrigy.com/info/Integr...stener_Securi=
ty.pdf),
and NGSSoftware (http://www.nextgenss.com/papers/hpoas.pdf).

Happy reading!
