With the rise of mercenary adware and different focused threats, tech giants like Apple, Google, and Microsoft have spent the previous couple of years attempting to determine the right way to defend the digital lives of their most at-risk, susceptible customers world wide. On cell, 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 value it for a public determine, activist, journalist, or dissident dwelling beneath day by 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 susceptible 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 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 doable and cut back interactions with unsecured internet providers and beforehand unknown, untrusted people. Superior Safety on Android is supposed to be as usable and versatile as doable, although, leaning on Google’s quickly increasing on-device AI scanning capabilities to offer monitoring and alerts with out having to utterly eradicate 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 classes of things that we use to defend the user. One is you obviously harden the system, so you try to lock things down, you prevent many forms of attacks,” says Dave Kleidermacher, vice president of engineering at Android’s security and privacy division. “But two is you can’t always prevent every attack entirely. But if you can detect that you’ve been compromised, you can take some sort of corrective action. In consumer security on mobile this detection has never really been a possibility, so that’s one of the big things we’ve done here.”
This monitoring and detection capability, known as Intrusion Logging, uses end-to-end encryption to indelibly store logs from your device in the cloud such that they can’t be accessed by Google or any party aside from you, but also in a form that can’t be deleted or modified, even if your device and Google account are compromised.

Logging and system monitoring tools are common on laptops and desktops—not to mention in enterprise IT environments—but offering the capabilities for consumers on mobile devices is more unusual. As with any scheme that takes data off a device and puts it in the cloud, the system does introduce some new risks, but Google and Google Cloud Services already run many end-to-end encrypted platforms for users, and Kleidermacher notes that the ability to create indelible logs that can’t be manipulated or deleted by a sophisticated attacker is invaluable in addressing targeted attacks.
“The main innovation here is you have an audit log mechanism to detect compromise that is actually resistant to device tampering,” he says. “It’s bringing intrusion detection to the consumer. So if you as a consumer suspect a problem and you’re not sure, you can pull the logs down from the cloud. You can share them with a security expert, you can share them with an NGO, and they can use tools for analysis.”
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 use a reminiscence vulnerability resembling a so-called buffer overflow, MTE will trigger the method to fail, stopping the assault in its tracks. Reminiscence corruption bugs are a typical instrument utilized by hackers, so neutering your complete class of vulnerabilities makes it rather more tough to assault a tool.
