If you spend more than a few hours a month doing patching, if you just flip on automatic updates and hope for the best, then you’re doing it wrong. Patch management software can help you develop and test your plan, test your patches, roll them back when needed. Test “in production”: No, I don’t mean that you should just patch every system without testing. Test a handful of servers and workstations that people actually use, and patch them before the rest of the network. Use reporting: Trust, but verify is the mantra of patch management.
