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.

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.

Incorporating a Prevention Mindset into Threat Detection and Response
Threat detection and response systems, by definition, are reactive because they have to wait for damage to be done before finding the attack. With a prevention-mindset, security teams can proactively anticipate the attacker's next move, rather than reacting to specific threats or trying to detect the latest techniques in real-time. The report covers areas enterprises should focus on: What positive response looks like. Improving security hygiene. Combining preventive actions with red team efforts.
