Web Security Projects
We have built a principal-based browser architecture to detect, quarantine, and
prevent various web-borne security threats, which happen within, across, and
outside web principals. We define a web principal, as borrowed from operating
systems, an isolated security container of resources inside the client browser.
To understand the aforementioned web-borne security threats, we have proposed
using crowdsourcing techniques to detect patterns of intra-principal
threats, i.e., add-on cross-site scripting (XSS), as well as vulnerability signatures to
detect patterns of an
outside-principal threat, i.e., drive-by download attacks.
We propose a
two-step prevention mechanism, which first proactively quarantines those
threats, and then, reactively modifies and protects existing infrastructures
from those threats. My proactive approach quarantines XSS attacks inside iframes
to cut off their further propagation path; my reactive
approaches first redefines web browser principal boundaries by a new client-side access
control policy, then make those client-side principals stronger by either
virtualization or proxy, and at last connect those
principals by a secure channel. The classification of the Web security is shown in
