چکیده

Passwords are the linchpin in the security of an increasing number of online services – services that range from social networking to business communication to banking. Given their importance, it is unfortunate that passwords are relatively easily stolen using a number of different types of attack. We introduce HyperPass: an approach and proof-of-concept system that aims to prevent some of these attacks by moving passwords from a user’s normal operating environment into a secure hypervisor. Notably, this is done while maintaining compatibility with existing online services, applications, and operating systems.

Safe Passage for Passwords and Other Sensitive Data

The prevalence of malware such as keyloggers and screen scrapers has made the prospect of providing sensitive information via web pages disconcerting for security-conscious users. We present Bumpy, a system to exclude the legacy operating system and applications from the trusted computing base for sensitive input, without requiring a hypervisor or VMM. Bumpy allows the user to specify strings o...

A Hypervisor Based Security Testbed

We are developing an experimental testbed intended to help support security research. The testbed allows a network of unmodified hosts, running any of several of unmodified operating systems, to execute in a controlled and reproducible manner. The network is implemented on a hypervisor that is instrumented to observe and control security-relevant events. These events are securely logged to a re...
