# iOS 26.3 Security Update Trials New ‘Background Security Enhancements’ System
If you’re using the iOS 26.3 beta, Apple has recently made available a new security update for installation. However, this update does not provide any fixes; it aims to evaluate a new system.
## Update Overview
As the new year rolls in, Apple is anticipated to release additional betas for iOS 26.3, iPadOS 26.3, and beyond. Recently, Apple delivered a distinctive update for beta testers, labeled ‘iOS 26.3 (a)’. This update functions as a trial for the newly restructured ‘Background Security Enhancements’ system.
### Getting the Update
In contrast to standard updates accessible via the Software Update section, this particular one can be found under Privacy & Security ⇾ Background Security Enhancements. This update is part of a significant revision initiated with iOS 26.1, which unveiled the Background Security Enhancements system but has not been deployed by Apple until now.
### Main Features of the Update
The release notes for the iOS 26.3 (a) update specify that this Background Security Enhancement is solely for testing and does not include any security fixes. The installation procedure resembles a regular Software Update, though it is located in a different menu.
After installation, users can choose to remove the update directly from the same Settings screen. If a user decides to uninstall the update, their iPhone will restart, and the security update will be erased.
### Prospective Consequences
This testing phase may suggest that Apple intends to introduce the Background Security Enhancements to all users shortly.
### Update 1/8
Just two days following the initial test security update, Apple issued a subsequent update, ‘iOS 26.3 (b)’, for beta users. Like its predecessor, this update is also strictly for testing and does not include real fixes.
In conclusion, the iOS 26.3 beta is presently in a testing phase for a new security system, with updates available for users to investigate.
