Meltdown and Spectre vulnerabilities affect a large portion of the world computer processors, enabling attacks on a large number of personal and business computers. We’ve already addressed how to handle these vulnerabilities in the Public Cloud. But there are also other possibilities that can help you protect your data from these attacks on your computer. Here’s a little tip on how you can defend from Meltdown and Spectre in Google Chrome.

Google Chrome browser currently offers a feature called “Strict site isolation” that could be defined as the second line of defence against attacks like Meltdown & Spectre. Strict site isolation is a security feature in Chrome that provides additional protection against some types of security bugs.

Due to Meltdown and Spectre vulnerabilities, seemingly innocent sites might be able to access or steal information by just running a crafted JavaScript code. With this Google Chrome feature, it will be harder.

Strict Site Isolation ensures that pages from different websites are always put into different processes, each running in a sandbox that limits what the process is allowed to do. It also blocks the process from receiving certain types of sensitive documents from other sites. As a result, a malicious website will find it more difficult to steal data from other sites, even if it can break some of the rules in its own process.

Enabling Strict Site Isolation to defend from Meltdown and Spectre in Google Chrome

Steps to follow to enable it:

1. On your computer, open Chrome.

2. In the address bar at the top, enter


 and press Enter.

3. Next to “Strict site isolation,” click Enable.
