Gazelle web browser, announced in 2009, is constructed as a multi
principle operating system and is a more secure browser than the ones already
The research team at Microsoft along with several other researchers at
technology oriented universities has undergone a publication. In the thesis thus
published, a secure web browser and what it should look like has been outlined.
Several security issues have been raised and a subtle hint has been planted
regarding the direction of the Internet Explorer in the future.
The Gazelle Browser: Microsoft proposes a more secure browser in the
name of Gazelle. The Gazelle web browser is the newly proposed browser which is
inbuilt with concepts pertaining to operating systems. Earlier, browsers were
used to show static pages and therefore were not much important. In recent
times, however, browsers have gained much more importance as they are made to
handle complex applications and are required in the field of social networking,
online banking, editing texts and many others.
Websites of today are seen featuring contents from different principals in
one single page. A number of subdomains are featured in one webpage. For
example, YouTube may be considered. A page featuring a YouTube video may also
contain video contents and advertisements from other pages in addition to its
original video content. This presence of different principals within the same
page involves a certain amount of risk as a bad code if drawn from an ad page
can cause the whole page to crash.
With the Gazelle browser the process- per- tab model that is showcased by the
Internet Explorer 8 and Google Chrome is taken to an extreme. Along with this
the new browser is blessed with added functionality. In Gazelle, the operating
system is topped by a browser kernel which manages the different principals and
prevents them from hampering one another. The process of operating system is
sandboxed individually for each of the principals. In this process, plugins are
treated as individual principals and therefore they do not affect the rest of
the page. This is the same with an ad box which has a bad code.
What the research team has to say: The fact that Microsoft proposes
a more secure browser is making news everywhere. The research team has
branded this browser as being strictly for research purposes. Furthermore, it
has been stated that this browser is not about to replace the Internet Explorer
right away. There has not been any statement regarding the commercialization of
the browser in any way whatsoever. Though the Gazelle is being hyped, there are
some disadvantages to it as well. For instance, it functions slower than the
Internet Explorer 8, especially, when opening up new sites.
As per the tech report published by Microsoft on 19th February
2009, this is what the research team has to say about the browser- cum-
operating system: “Our prototype implementation and evaluation experience
indicates that it is realistic to turn an existing browser into a
multi-principal OS that yields significantly stronger security and robustness
with acceptable performance and backward compatibility.”
