Mainframe Security Part 1: System Integrity
I’m often asked about what installations can do to maximize their data security in an IBM mainframe environment. For those that do not know me, I was one of the people who started the data security initiative in the mainframe environment when I was asked to form the SHARE Security Project in 1972. We worked together to create a series of requirements to be presented to IBM and I did that in 1974. For more details on this, see www.share-sec.com/history.html.When IBM delivered RACF in 1976, it did not meet two of the crucial requirements – protection by default and what we called algorithmic grouping of resources.
