Η ομάδα του Project Fission της Mozilla ετοιμάζεται να εφαρμόσει ένα νέο χαρακτηριστικό ασφάλειας στον Firefox που θα απομονώνει τις ιστοσελίδες. Κάτι παρόμοιο uses και η Google στην έκδοση 67 του προγράμματος περιήγησης Chrome, για να μετριάσει τις side-channel attacks by malicious websites.
The flaws security which the Mozilla Foundation wants to protect the Firefox user from with Project Fission were reported in Google's Project Zero on 3 January of 2018.
The Specter (variants 1 and 2) and Meltdown (variant 3) vulnerabilities allow attackers to abuse CPU data caching time "to leak information. "
The vulnerabilities mentioned above were fixed immediately by Firefox security teams, but it was observed that new attacks through other side-channels can affect Firefox users when they visit a notorious website.
According to Nika Layzell of Mozilla Project Fission:
Our goal is to create a browser that will not only be secure against known security vulnerabilities, but will also have layers of built-in defense against potential future vulnerabilities. To achieve this, we need to refresh the Firefox architecture to support the complete isolation of the site.
We call this the next step in the evolution of Firefox process model "Project Fission". With Project Fission, we will "split the individual", dividing the cross-site iframes into different processes from the parent frame (s.s .: the frame that contains them).
"This means that even if a Specter attack is launched by a malicious website, the data from other sites will generally not be loaded into the same process, so there would be much less data available to the attacker," said Google's Charlie Reis.
The first implementation of Project Fission in Firefox should be seen at the end of February 2019. Let's wait to see if all this affects the performance of the browser.
