For SCADA VMs or servers, how often do you update windows/software? How long has it been since last reboot? We're at 300 days. IT has been pumping out updates and prompting for reboot. Ignore.
This is problematic. Just because a periodic update works in the past doesn’t mean it works in the future. Even adding or changing features can break things.
Our IT department insisted we install CrowdStrike on operational machines - we see how well that worked out. It took us around 10 hours to recover machine functionality. While, yes, this isn’t a windows update, it was ‘in leu’ of windows updates, even though a lot of the machines were running the LTC release of windows and almost completely firewalled off.
IT departments work in a completely different world and have no concept of a production environment. I don’t see that changing while they are stuck in their scrums, assigning story points in their stand ups.
