Having spent my entire career with one foot on the "legacy" side of things (mainframe-like systems) and the other on the Wintel side, I can tell you that I've had to deal with any number of problems on the Wintel side that generally just wouldn't happen - and indeed in many cases couldn't happen - on the legacy side. As an example of how things are done on the legacy side, I was once dealing with a piece of Power hardware which could be configured as either a Linux system or an iSeries system. There was a USB port in the hardware which was enabled on Linux systems but disabled on iSeries systems, and AFAIK it couldn't be enabled, either. This puzzled me at first, until I found out how USB ports can be used to attack systems and then it made perfect sense - they had chosen to disable the USB port for security reasons. |
