This is an excellent paper, truly very very well written. I am a fan of Arups HIPAA book because of its very easy reading style. he has not lost any of the style here. This paper is called "Project Lockdown - A phased approach to securing your database infrastructure" and is a 4 part paper on securing an Oracle database. The paper is phased into 4 sections, what you can do in one day, what you can do in a week, what you can do in a month and finally what you can do in a quarter.
Excellent paper, well worth reading, well done Arup!!!
