DESCRIPTION:It is very difficult\, if not impossible\, to guarantee that l
 arge\, complex software programs are free of security vulnerabilities that
  can be exploited by attackers.  Even if only a small part of a large appl
 ication is security-critical\, and this part is carefully constructed and 
 statically analyzed to be secure\, it still executes at runtime with a sea
  of untrusted software.  In particular\, the commodity operating system ma
 y be compromised\, leaving security monitors in applications and middlewar
 e exposed.   We discuss the Bastion architecture whose design goal is to e
 nable trusted software modules to execute securely\, even when there is ma
 lware in the system and the O.S. may be compromised.  Bastion has a proces
 sor-hypervisor Trusted Computing Base\, with hardware trust anchors and me
 chanisms for protecting the hypervisor\, which then protects trusted softw
 are modules in the applications or O.S. space. Together with minimal trust
  chains\, Bastion also provides the architectural equivalents of sealed st
 orage and trustworthy attestation without using an external TPM chip.  We 
 discuss some of its defenses against both software and hardware threats\, 
 and its scalability to multiple trust domains.\n\nSpeaker’s Bio:\nRuby B
 . Lee is the Forrest G. Hamrick Professor of Engineering and Professor of 
 Electrical Engineering at Princeton University\, with an affiliated appoin
 tment in the Computer Science department. She is the director of the Princ
 eton Architecture Laboratory for Multimedia and Security (PALMS). Her curr
 ent research is in security‐aware computer architecture\, secure cloud c
 omputing\, trustworthy and resilient systems\, crypto acceleration\, secur
 e mobile computing\, secure embedded systems and DDoS mitigation. She is a
  Fellow of the Association for Computing Machinery (ACM) and a Fellow of t
 he Institute of Electrical and Electronic Engineers (IEEE). She is often a
 sked to help or co‐lead U.S. national efforts to improve cyber security 
 research. She is also Associate Editor‐in‐Chief of IEEE Micro and Advi
 sory Board member of IEEE Spectrum. She is a member of the Phi Beta Kappa 
 and Alpha Lambda Delta honoraries\, and various Who’s Who. She has been 
 granted over 120 United States and international patents.\nPrior to joinin
 g the Princeton faculty\, Dr. Lee served as chief architect at Hewlett‐P
 ackard\, responsible at different times for processor architecture\, multi
 media architecture and security architecture. She introduced multimedia in
 structions into microprocessors\, was a founding architect of HP’s PA‐
 RISC architecture and instrumental in the design of several generations of
  PA‐RISC processors for commercial and technical systems\, and also co
 ‐led an Intel‐HP IA‐64 architecture team. Concurrent with full‐tim
 e employment at HP\, Dr. Lee also served as Consulting Professor of Electr
 ical Engineering at Stanford University. She has a Ph.D. in Electrical Eng
 ineering and a M.S. in Computer Science\, both from Stanford University\, 
 and an A.B. with distinction from Cornell University.\n
