The vulnerability research team of Microsoft Edge explored a new feature called Super-Duper Secure Mode (SDSM). SDSM was close to making Chromium-based Edge more secure without negatively striking achievement.
These include authorizing the new Control-flow Enforcement Technology (CET) in Edge, which extends the process. And in the prospect of adding support for Web Assembly, Arbitrary Code Guard (ACG), and other advance security mitigations.
With the V8 disabling, half of the V8 bugs would be removed. This means fewer security updates and hardly any emergency patches for users.
Microsoft noted that the relief of JIT is not all bad:
“Our tests that measured improvements in power showed a 15% improvement on the average and our generic showed around 11% increase in power depletion. Memory mixed story with negatively impacted tests is showing a 2.3% regression.”
Within few months, Microsoft plans to experiment with its Super-Duper Secure Mode. You will be able to try it out by validating its flag through edge://flags in Edge Canary, Dev, and Beta version.
