Start at the Beginning
1. use a secure O/S.

2. look into using Named Spaces

remember that in implementing RACF on an MVS system access had to be granted on an item by item basis.  this is fundamental to security.    it gives you control over who has access to do what using the various tools available.   Your access list is an auditable item.    make sure your auditor knows how you are controlling access.

restricting access to files based on user ID is inadequate for any user who is running programs of an un-known nature.   remember: modern documents -- web pages, e/mail, and such must be treated as executable files where it is possible that the documents contains or links to something that is executable.

2014 has been headlined as "The Year of the Hack".    unless we start doing things differently 2015 will be more of the same.   Change will be painful as it so often is.   But at some point it becomes the only acceptable option.

As long as you don't pull it after an attack--then there's no forensics trail. =)
