The main way to protect Super Duper Secure Mode users from attack is to disable a browser technology known as the Just In Time Engine (JIT), whose role is to accelerate Javascript Work.

According to Johnathan Norman, Microsoft Edge Vulnerability Research Lead, about half of all security issues affecting the V8 JavaScript engine are caused by the JIT. So by disabling JIT, Microsoft is able to dramatically reduce the threat level in one fell swoop.

When activated, Super Duper Secure Mode also enables control-flow enforcement technology (CET), a hardware-based exploit mitigation from Intel, and Arbitrary Code Guard (ACG). Both security features were previously set to Off by default for performance reasons.

“Performance and complexity often come at a cost, and often we bear this cost in the form of security bugs and subsequent patches,” wrote Norman when the new mode was first announced.

“This reduction in attack surface kills half of the bugs we see in exploits and makes each remaining bug more difficult to exploit. In other words, we reduce costs for users but costs for attackers.” increase in.”

Super Duper Secure Mode can be switched on under the Privacy tab in the Edge settings menu.
