With the rise of mercenary spy ware and different focused threats, tech giants like Apple, Google, and Microsoft have spent the previous couple of years making an attempt to determine easy methods to shield the digital lives of their most at-risk, weak customers world wide. 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 need to make, however that could possibly be very price it for a public determine, activist, journalist, or dissident dwelling beneath day by day scrutiny and risk of assault. For years, Google has provided a program for a similar demographic referred to as Superior Safety that focuses on including additional layers of monitoring and safety to weak customers’ Google accounts, a core piece of many individuals’s digital lives that could possibly be devastating if compromised. Now, Google is extending Superior Safety with a set of options for Android 16.
On Tuesday, the corporate introduced an Advanced Protection mode for telephones working the most recent model of Android. At its core, the mode is designed round imposing robust safety settings on all apps and providers to silo knowledge as a lot as attainable and scale back interactions with unsecured net 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 utterly get rid of options. Nonetheless, the mode imposes restrictions that may’t be turned off, like blocking telephones from connecting to historic 2G knowledge networks and disabling Chrome’s Javascript optimizer, which may alter or break some net performance on some websites.
“There are two courses 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 stop many types of assaults,” says Dave Kleidermacher, vice chairman of engineering at Android’s safety and privateness division. “However two is you may’t all the time stop each assault completely. However when you can detect that you’ve got been compromised, you may take some kind of corrective motion. In client safety on cellular this detection has by no means actually been a chance, in order that’s one of many huge issues we have completed 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 social gathering other than you, but additionally in a kind 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 all scheme that takes knowledge 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 classy attacker is invaluable in addressing focused assaults.
“The principle innovation right here is you could have an audit log mechanism to detect compromise that’s really proof against system tampering,” he says. “It is bringing intrusion detection to the buyer. So when you as a client suspect an issue and also you’re unsure, you may pull the logs down from the cloud. You possibly can share them with a safety professional, you may share them with an NGO, they usually 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 reminiscent of a so-called buffer overflow, MTE will trigger the method to fail, stopping the assault in its tracks. Reminiscence corruption bugs are a standard device utilized by hackers, so neutering the whole class of vulnerabilities makes it rather more tough to assault a tool.
