I am very intrigued as to how mainframes seem to be much more secure than the servers. Malware targeted are mainframes are very rare.
It is due to security through obscurity? Since few people have access to mainframes and in-depth knowledge on mainframes, it is difficult to develop malware for mainframes.
Or is it due to the architecture of mainframes? Certain characteristics such as read-only memory that make it difficult to penetrate or compromise.
If it is the latter, is it possible to adopt these characteristics for our modern day server architecture?
I have tried googling but it is quite difficult to find material on mainframes in general. Thanks for your response.
