In one of its latest official blogposts, Google has discussed how its Chrome web browser qualifies against hacks. This comes soon after a report by tech giant Project Zero revealed that attacks through web browsers have increased since 2019.

What about Chrome is anti-hacking?
Google blogpost outlines that Chrome has Site Isolation features which is a multilayer system wherein a single bug is “almost never” powerful or sufficient enough to cause any hack attacks. Additionally, due to this, the hackers would also need to be using multiple bugs that can either compromise the rendered process or get inside the browser, or even inside the OS.

Furthermore, Site Isolation is a high profile security feature offered by Google’s Chrome web browser that boasts an extra level of security against spam from unreliable websites. 

How does Chrome’s anti-hackers feature work?
How the Site Isolation feature in Chrome browser operates is by using the browser’s sandbox for making it even more difficult for malicious websites to hack or steal information from user accounts on other websites. 
This particular process of Site Isolation revolves around putting the pages from various websites into dozens of different processes, wherein each runs into a sandbox that puts limitations on what the processes are allowed to do. In turn, this makes it really tough for suspicious websites to steal data and information from other websites.

As Google describes it, Site Isolation implementation works in the following manner – “Cross-site documents are always put into a different process, whether the navigation is in the current tab, a new tab, or an iframe (i.e., one web page embedded inside another).”

Cross-site data such as JSON, HTML, XML and PDF are not delivered to the web page’s processes unless the server explicitly allows permission using CORS.

Usually, security checks that are in the browser process are able to detect and terminate a misbehaving rendered process on desktop platforms presently.

How can Chrome users stay secure?
In its official blog post, Google has also sounded advice to all its users, guiding them to keep updating their Chrome browser frequently and timely since the bugs that are already patched can be used by attackers to target their older Chrome versions.

Google has said that it is working closely in improvising and strengthening the powerful SIte Isolation feature, with Android being its main focus since the current one prioritizes desktop users. The tech giant has informed that it is also coordinating efforts to add more security layers and make the Chrome web browser shields more unsurpassable. They explained that the extra layers are aimed at making a single bug almost negligibly effective so that it requires multiple chained bugs for casing any potential harm.
