With the rise of mercenary adware and different focused threats, tech giants like Apple, Google, and Microsoft have spent the previous few years making an attempt to determine shield the digital lives of their most at-risk, weak customers around the globe. On cellular, the launch of Apple’s iOS Lockdown Mode in 2022 was one concerted effort to shed nonessential performance in favor of most safety—a trade-off most customers would not wish to make, however that may very well be very value it for a public determine, activist, journalist, or dissident dwelling underneath each day scrutiny and menace of assault. For years, Google has provided a program for the same demographic referred to as Superior Safety that focuses on including extra layers of monitoring and safety to weak customers’ Google accounts, a core piece of many individuals’s digital lives that may very well be devastating if compromised. Now, Google is extending Superior Safety with a collection of options for Android 16.
On Tuesday, the corporate introduced an Superior Safety mode for telephones operating the most recent model of Android. At its core, the mode is designed round imposing sturdy safety settings on all apps and providers to silo information as a lot as attainable and scale back interactions with unsecured internet providers and beforehand unknown, untrusted people. Superior Safety on Android is supposed to be as usable and versatile as attainable, although, leaning on Google’s quickly increasing on-device AI scanning capabilities to supply monitoring and alerts with out having to fully get rid of options. Nonetheless, the mode imposes restrictions that may’t be turned off, like blocking telephones from connecting to historic 2G information networks and disabling Chrome’s Javascript optimizer, which may alter or break some internet performance on some websites.
“There are two lessons of issues that we use to defend the consumer. One is you clearly harden the system, so that you attempt to lock issues down, you forestall many types of assaults,” says Dave Kleidermacher, vp of engineering at Android’s safety and privateness division. “However two is you’ll be able to’t all the time forestall each assault solely. However in the event you can detect that you’ve got been compromised, you’ll be able to take some type of corrective motion. In shopper safety on cellular this detection has by no means actually been a chance, in order that’s one of many huge issues we have accomplished right here.”
This monitoring and detection functionality, generally known as Intrusion Logging, makes use of end-to-end encryption to indelibly retailer logs out of your system within the cloud such that they can not be accessed by Google or any get together apart from you, but additionally in a type that may’t be deleted or modified, even when your system and Google account are compromised.

Logging and system monitoring instruments are widespread on laptops and desktops—to not point out in enterprise IT environments—however providing the capabilities for customers on cellular gadgets is extra uncommon. As with every scheme that takes information off a tool and places it within the cloud, the system does introduce some new dangers, however Google and Google Cloud Providers already run many end-to-end encrypted platforms for customers, and Kleidermacher notes that the power to create indelible logs that may’t be manipulated or deleted by a complicated attacker is invaluable in addressing focused assaults.
“The primary innovation right here is you’ve got an audit log mechanism to detect compromise that’s really immune to system tampering,” he says. “It is bringing intrusion detection to the patron. So in the event you as a shopper suspect an issue and also you’re undecided, you’ll be able to pull the logs down from the cloud. You possibly can share them with a safety professional, you’ll be able to share them with an NGO, and so they can use instruments for evaluation.”
One other characteristic that’s on by default and cannot be turned off in Superior Safety is Android’s Reminiscence Tagging Extension (MTE). The characteristic, which debuted for Google’s Pixel line and is beginning to be adopted in processors on different gadgets, is a {hardware} safety safety associated to how a system manages its reminiscence. If an attacker makes an attempt to take advantage of a reminiscence vulnerability equivalent to a so-called buffer overflow, MTE will trigger the method to fail, stopping the assault in its tracks. Reminiscence corruption bugs are a standard software utilized by hackers, so neutering the complete class of vulnerabilities makes it far more tough to assault a tool.
