Apple released iOS 26.3.1 (a) on March 17, and the company wrote online that it fixed an issue in WebKit, the engine that powers Safari and other third-party browsers in iOS. This was also the first Background Security Improvement Apple released. Downloading those updates as soon as possible helps keep you and your device safe, and Apple made it easy to keep up with updates with Background Security Improvements in iOS 26.1.
"Background Security Improvements delivers lightweight security releases for components such as the Safari browser, WebKit framework stack and other system libraries that benefit from smaller, ongoing security patches between software updates," Apple wrote online.
This feature reminds me of Apple's Rapid Security Responses the company introduced in 2023. The RSR updates were a way for the company to quickly deploy security fixes to devices, but Apple hasn't issued an RSR since the release of iOS 16.5.1 (c) in July 2023.
Here's how to enable these improvements so they will be installed on your iPhone automatically.
Where to find Security Improvements
1. Tap Settings.
2. Tap Privacy & Security.
3. Tap Background Security Improvements near the bottom of the menu.
4. Tap the toggle next to Automatically Install.
Now your iPhone will download small security updates and install them on your device automatically.
