Mainframe vs. PC security
I would say this to those who thought mainframes are "inherently" more secure:

It is true that mainframe security is "easier" to maintain and an aggregate network of PCs. Once the mainframe itself is secured, all systems are secured, as opposed to securing all individual PCs in various configurations and network exposures. However, reserves is also true. If mainframe security is breached, the whole system goes down, whereas certain sections of a PC network might still be secured or can be made functional immediately after attacks. It's all about trade-offs and proper security postures for different computer systems.

Mainframe Security-Ness
Ray:  

Thanks for this. It's good to bring attention to the fact that the IBM mainframe needs securing as much as any machine that contains important assets. And since mainframes often run a company's most precious applications, the need to secure it is paramount - and important, too. ;)

Training, where can we get time to run practice workloads on a mainframe
I think the biggest problem is the lack of availability to work on a mainframe and to become familiar with it, one needs time to work on it to take into consideration the commands one has to run to ensure its availability and security. I know there is Z-Linux, ZOS but I can't go to a friend or neighborhood store or online and put the time in to master mainframe security procedures, there is a process of course.

Maybe you can shed some light, other than taking these expensive online classes or going to one of IBM's training facilities (Rockville, Gaithersburg, RTP or ATL).

Give me some of your thoughts.
