One way to improve the security of the Google Chrome browser is to enable the “strict site isolation” feature, which allows each process to process pages from only one site, thereby protecting each one separately.
In theory, this should protect you from various risks, like the threat of Meltdown and Specter exploits, but that does not mean that you do not have to update your browser regularly. New versions often contain fixes for various security bugs.
The function of site isolation is experimental. It’s pretty easy to turn on, but there are some nuances related to resource consumption.
How to enable site isolation in Google Chrome
The function “Strict Site Isolation” can be included in Google Chrome for Mac OS, Windows, Linux, Chrome OS and Android.
- Open the Google Chrome browser.
- Enter the following link in the address bar and go to it:
- Find the item “Strict site isolation” and click Enable.
- Click Restart at the bottom of the screen to apply the changes.
When Chrome restarts, the site isolation feature will be active, and the processes of each site will be protected separately.
Here is an explanation of the function “Strict Site Isolation” offered in the settings of Chrome:
Experimental security mode, through which each process can process pages of only one site.
But a more detailed explanation:
Site Isolation is an experimental security feature of the Chrome browser, which provides additional protection against various security bugs. With it, unreliable sites are more difficult to access your account information and even steal it.
Usually sites can not access other sites inside the browser, but sometimes bugs appear in the code, which allow to bypass this protection and make an attack. Team Chrome always tries to fix such bugs as quickly as possible.
Isolation of sites provides additional protection from such attacks. It separates the processes of the pages of each site and protects them separately. It also blocks the access of some sites to information from others. As a result, the site with the virus will be more difficult to steal data from another site, even if it manages to bypass the basic protection.
What are the disadvantages of the ” Site Isolation ” feature in Chrome?
One of the main disadvantages is the large consumption of memory and resources, especially when you have many tabs or windows open.
The function is experimental, so there may be other problems. However, tests showed only one thing – an increase in memory consumption.
The Chrome team warns that some tools may not work perfectly, but this should not be a problem for more users.
