Hello all -

Have people run into a lot, if any questions on security about Mainframes and OS/390? Our organization has them, but when I question anyone on the security of those devices I am met the response of RACF. Being naturally suspicious, I am wondering if anyone works with security still for mainframes? I question it because while mainframe technology is out "there", it doesn't pop up much on the radar for security and I don't think it's discussed here.

Thoughts?

TIA
