SECURELY ISOLATING WEB SITES
In this section, we investigate exactly which security ben-
ets can be achieved by visiting sensitive web sites in a
dierent web browser than non-sensitive web sites. We clas-
sify many common browser-based attacks and show that a
large number of them can be mitigated through the use of
multiple browsers. We then introduce two new mechanisms
in a single browser that can be used to achieve these same
benets, for particular web sites that choose to opt in and
accept the compatibility implications.
