Rapid Security Responses, according to Apple, may require you to restart your
iPhone when they go live and will be downloaded automatically by default.
However, you can disable automatic RSR downloads and simply receive the fixes
with every new iOS software update, as you did in the past. While RSR can be
disabled, it's a good idea to have automatic downloads enabled so that your
device is always running the most up-to-date security software. Rapid Security
