In this last time, we have seen many new functions and features in Microsoft Edge with the idea of bringing more security to the browser and enabling Super Duper security mode is one of these. This mode will allow us to improve the security of our browser and computer while we browse the web..
What is Super Duper Security Mode?
Many times, even the best antiviruses can't do all the work and need a little help. Super Duper security mode is a feature that is capable of bringing noticeable security improvements to Microsoft Edge without affecting browser performance.
The Microsoft security team found that the V8 JavaScript engine is to blame for many security vulnerabilities. The JavaScript engine uses "Just-in-Time" (JIT) compilation to speed up JavaScript code on websites, but it also opens up some vulnerabilities..
According to statistics, nearly 45% of the vulnerabilities found in the V8 JavaScript engine and WebAssembly are closely related to JIT. More than half of exploited Chrome vulnerabilities take advantage of these bugs as well.
When enabled, Super Duper safe mode removes the Just-in-Time (JIT) compilation of JavaScript V8. Eliminating in this way, a door for attackers to enter our system..
JIT exists to speed up our browser, but Microsoft says disabling it doesn't always have a negative performance impact. Super Duper gives the possibility of launching Control-flow Enforcement Technology (CET), it is an exploit prevention tool that is based on Intel hardware that improves Edge security much more.
How to activate it
The first thing we will do is open the browser on our computer, regardless of whether we use Linux, Mac or Windows, the process is the same. We click on the three points that are in the upper right corner and in the drop-down menu we will click on “Settings”.
Next, let's head over to “Privacy, Search, and Services” on the left sidebar.
We scroll down until we find the section "Improve your security on the web" and we will have to enable it by clicking on the switch on the right side. In previous versions of Edge, the name of this section will be “Enable security mitigations for a safer browsing experience”.
Here we will have the possibility to choose between the “Balanced” and “Strict” modes. Balancing only affects websites that we don't visit very often. While the strict one applies to all websites.
We can also add exceptions, we can add any site to the list so that Super Duper safe mode does not apply to these websites.
