I have the original IPad Air 2013. I understand that there will be no more IOS updates for this model. What about security updates. Will I be more vulnerable to whatever?
From time to time, Apple releases security updates for devices like yours. A few weeks ago, iOS 12.4.3 has been published, e.g., for iDevices running iOS 12, but not iOS /iPadOS 13. So if your iPad isn‘t on iOS 12.4.3, update it.
