Zusammenfassung:
Today's software monoculture creates asymmetric threats. An attacker
needs to find only one way in, while defenders need to guard a lot of
ground. Adversaries can fully debug and perfect their attacks on their
own computers, exactly replicating the environment that they will
later be targeting. Software diversity raises the bar to attackers. A
diversification engine automatically generates a large number of
different versions of the same program, potentially one unique version
for every computer. These all behave in exactly the same way from the
perspective of the end-user, but they implement their functionality in
subtly different ways. As a result, a specific attack will succeed on
only a small fraction of targets and a large number of different
attack vectors would be needed to take over a significant percentage
of them. Because an attacker has no way of knowing a priori which
specific attack will succeed on which specific target, this method
also very significantly increases the cost of attacks directed at
specific targets. We have built such a diversification engine which is
now available as a prototype. We can diversify large software
distributions such as the Firefox and Chromium web browsers or a
complete Linux distribution. Some preliminary insights will be
presented as well as some practical issues, such as the problem of
reporting errors when every binary is unique.
Kurzbiographie von Michael Franz
Michael Franz is the director of the Secure Systems and Software
Laboratory at the University of California, Irvine (UCI). He is a Full
Professor of Computer Science in UCI's Donald Bren School of
Information and Computer Sciences and a Full Professor of Electrical
Engineering and Computer Science (by courtesy) in UCI's Henry Samueli
School of Engineering. Prof. Franz was an early pioneer in the areas
of mobile code and dynamic compilation. He created an early
just-in-time compilation system, contributed to the theory and
practice of continuous compilation and optimization, and co-invented
the trace compilation technology that eventually became the JavaScript
engine in Mozilla's Firefox browser. Franz received a
Dr. sc. techn. degree in Computer Science (advisor: Niklaus Wirth) and
a Dipl. Informatik-Ing. ETH degree, both from the Swiss Federal
Institute of Technology, ETH Zurich.
