Microsoft Edge for MacOS gets some exciting security updates

Super-Duper Secure Mode for Microsoft Edge browser is developed for macOS. This is a feature that improves browser security without affecting performance by disabling Edge’s “Just-in-Time-Compilation” JavaScript interpreter.

As reported by MSPoweruser, using the JIT engine can improve website performance, but the Microsoft Browser Vulnerability Research Team says its use can be the root of many browser vulnerabilities. It suggests there is.

“Performance and complexity are often costly, and we often bear these costs in the form of security bugs and subsequent patches,” explains Microsoft. “Looking at Common Vulnerabilities and Exposures (CVE) data as of 2019, we can see that approximately 45% of CVEs published for V8 are related to the JIT engine.”

Security support for Mac devices with Edge
Super-Duper Secure Mode may sound like a name made on the fly. Microsoft says it could be called a little more “professional” in the future, but this feature has been around for a while on Windows devices. And it’s already in use for testing in Edge Beta, Dev, and Canary (though behind the experimental flags).

As mentioned in Johnathan Norman’s tweet above, this feature is disabled by default on all Edge Insiders on a few websites such as FaceBook and YouTube due to a corruption issue caused by SDSM. Nevertheless, Microsoft plans to give users control over the features and where they can be applied in future updates.

Microsoft wants Super Duper Secure Mode to be “something that will change the modern exploit environment and significantly increase the cost of an attacker’s exploit.”

There’s still a lot of testing to be done within the Insider channel before it’s generally available on macOS, but if you’re particularly excited, you can try the current version of SuperDuper Secure Mode on Microsoft Insider Canary branch. ..

Extra security for M1-based Macs
SDSM isn’t the only thing Microsoft has prepared for Mac users. The announcement, released on August 25, updated Defender for Endpoint with native support for M1 Macs and Apple Silicones, forcing users to use the Rosetta 2 emulator to run the software.

“This update provides the latest integration pack designed to work seamlessly on M1 and Intel-based Mac devices,” program manager Helen Allas wrote on Microsoft’s official blog.

“With native M1 support, Microsoft Defender for Endpoint on Mac no longer requires the Rosetta2 emulator to work on M1-based Big Sur devices. Microsoft Defender for Endpoint does not explicitly take action on Rosetta2. Rosetta2 takes no action on the device. It is your or your organization’s responsibility to remove devices you no longer need. “

Analysis: Mac users are currently doing well

In the past, Mac owners have used tools like Apple Rosetta to run unoptimized applications, but further development of native support for the new M1 architecture is welcome. .. Although there are applications, emulation often degrades performance because conversion requires valuable computer resources.

Given the frequency of using the web browser, the performance drop is very noticeable and can be a frustrating experience if you rely on emulation to perform the required tasks.

Fortunately, a number of updates and features have been released in recent months since the release of the M1 SoC. This means you can now run many applications that require native emulation. As Apple continues to move from Intel chips to its own custom silicon, users are expected to become less dependent on Rosetta 2.

New products are expected to be available in the coming months (the remarkable new MacBook Pro model is expected to include the powerful new M1X SoC), and Apple’s leading chip supplier, TSMC, has ordered Apple. Is in stock because we give it a priority. Mac users.
